A character cannot cast a spell while falling, unless the fall is greater than 500 feet or the spell is an immediate action, such as feather fall. Casting a spell while falling requires a concentration check with a DC equal to 20 + the spell's level. Casting teleport or a similar spell while falling does not end your momentum, it just changes your location, meaning that you still take falling damage, even if you arrive atop a solid surface.

====General Collisions Rules====
Adventurers frequently bash themselves into things through various circumstances. For example, a Barbarian sees a Drow Matriarch with no escorts, so he charges her full speed...only to find the Force Wall in the way.  He smashes into the wall full speed, but how much does that hurt?  This is treated as a collision, which is a more general case of Falling damage.  In this case, since he was in a Charge maneuver which reduced his armor class, he was not considered to be moving cautiously. As a result, he takes 1d6 of damage per ten feet of his speed at the moment of the collision. If he has a base speed of 50 feet and a Haste spell to raise his speed to 80, then he takes 8d6 from this collision. Ouch.  It's made even worse my the Matriarch laughing....
If he was not moving in a precipitous manner, ie, a normal move at his base speed, he would only take 1d6 per thirty feet of his movement at most. In many cases, such a result would cause no damage at all, since that is the reward for moving cautiously. The Game Master adjudicates all cases of collision damage, and are encouraged to keep it fun and interesting, and maybe even show a little mercy.
Collisions are used for many things, such as being swept away down a boulder-strewn gully by a flash flood, or being run over by that huge round stone that rolled out of the ceiling in that lost temple, or when that nobles carriage runs wild down the streets, or even when the hapless adventurer is being dragged along the ground behind a racing horse. Any time an object bangs into an adventurer in an uncontrolled and violent fashion, this can be resolved using these collision rules, which are that the adventurer takes 1d6 per ten feet of speed, and if it's lethal damage, they are knocked prone by the experience.
Note, being dragged by a horse really sucks, you want to get out of that as soon as possible.

Just as characters take damage when they fall more than 10 feet, so too do they take damage when they are hit by falling objects.
 
Just as characters take damage when they fall more than 10 feet, so too do they take damage when they are hit by falling objects. Note that falling object damage is resolved differently from collisions, because falling objects are typically thrown by a bad guy, rather than being environmental hazards.


Objects that fall upon characters deal damage based on their size and the distance they have fallen. Table: Damage from Falling Objects determines the amount of damage dealt by an object based on its size. Note that this assumes that the object is made of dense, heavy material, such as stone. Objects made of lighter materials might deal as little as half the listed damage, subject to GM discretion. For example, a Huge boulder that hits a character deals 6d6 points of damage, whereas a Huge wooden wagon might deal only 3d6 damage. In addition, if an object falls less than 30 feet, it deals half the listed damage. If an object falls more than 150 feet, it deals double the listed damage. Note that a falling object takes the same amount of damage as it deals.

Dropping an object on a creature requires a ranged touch attack. Such attacks generally have a range increment of 20 feet. If an object falls on a creature (instead of being thrown), that creature can make a DC 15 Reflex save to halve the damage if he is aware of the object. Falling objects that are part of a trap use the trap rules instead of these general guidelines.

===Difficult Terrain===
===Difficult Terrain===
Some terrain is too tricky to move through at normal speed.  Such terrain is called "difficult" though this can encompass many scenarios: obstacles, slippery or unstable footing, steep slopes, etc.  When moving through difficult terrain, each square moved into counts as two squares (10 feet), effectively reducing the distance that a character can cover in a move.  Characters cannot run or charge through difficult terrain, nor can they take 5-foot steps.

===Cutting Corners===
===Cutting Corners===
On a square grid, in clear terrain, a character may move into any of the eight squares adjacent to their current square. Moving through an edge is considered "moving straight", and moving through a corner is considered to be "cutting the corner". Cutting a corner may or may not be possible, depending on the nature of any items that fill a square. If the item completely fills the square, such as the corner of a dressed stone hallway, the edge of a door in a flat wall, or a square pillar that fills the space completely, then you cannot cut a corner to skim past that space. If the item fills the space such that you cannot occupy the space (without being incorporeal or other means), but, does not completely fill the space, then you can still cut the corner to move diagonally past it.  Examples are large trees, round pillars, most natural stone walls, etc.

For example, a 30-foot cone with Widen Spell applied grows from a 5x5 square to a 10x10 square.

Standard Ground-Based Movement

Move

Type of Action: Move

A character can move its speed with a move action. For most size-medium creatures, this is 30 feet. Moving like this is a cautious walk, and is primarily used during combat. Characters can only move through unoccupied spaces or spaces occupied by allies, though any move must end in an unoccupied space.


Double Move

Type of Action: Full attack action (standard and a move)

A character can move twice its listed speed by performing a double-move. This is usually done by converting the character's standard action for the round down to a move action, and then using the character's move action to move again. Note that a double-move is treated as a single action, so there is no need for the space between the two move actions to be unoccupied, though the character must (obviously) still be able to move through the space legally.


Run

Type of Action: Full round action

A character may declare a 'run' action as a full-round action. Running allows the character to move up to four times its listed speed in a straight line (or three times its listed speed if it is wearing heavy armor). The character loses any Dexterity bonus to AC unless it has the Run feat. If a character declares a 'run' action, it may not make a 5-foot step during the same round (except with an action point, or a class ability like the prowler's "Shifty").

A character can run for a number of rounds equal to its Constitution score, but after that it must make a DC 10 Constitution check to continue running. The character must check again each round in which it continues to run, and the DC of this check increases by 1 for each check it has made previously. When it fails this check, it must stop running. A character that has run to its limit must rest for 1 minute (10 rounds) before running again. During a rest period, a character can move no faster than a normal move action.

Characters using the 'run' action can't cross difficult terrain. Characters may not use the 'run' action if they cannot see.


5-Foot Step

Type of Action: Free action

A creature can move 5 feet in any round in which it doesn't perform any other kind of movement. Taking this 5-foot step never provokes an attack of opportunity. Creatures cannot take more than one 5-foot step in a round, and cannot take a 5-foot step in the same round in which it moved any distance through its own actions (e.g. moving, charging, spring attack, jab, casting a spell that moves the creature from its starting location, etc.). Standing up from prone is also considered movement, thus disallowing 5-foot steps.

A creature can take a 5-foot step before, during, or after its other actions in the round. A 5-foot step can even be used between attacks during a full attack action.

A creature can only take a 5-foot-step if its movement isn't hampered by difficult terrain or darkness. Any creature with a speed of 5 feet or less can't take a 5-foot step, since moving even 5 feet requires a move action for such a slow creature.

No creature may take a 5-foot step using a form of movement for which it does not have a listed speed.

If a creature has an action point which can be used to grant a move action, it may spend the action point to take a 5-foot step, even if it has previously moved this round, or has already taken a 5-foot step. Using action points in this manner deliberately breaks the normal rules for 5-foot steps, since action points are meant to simulate creatures performing truly heroic deeds.

Some classes (e.g. Prowlers) and races (e.g. Half-Orcs) have special abilities which allow them to make more than one 5-foot step in a single round, or in rounds in which they have already moved. In those cases, follow the rules listed for the race or class to determine how they break the limitations for normal creatures using a 5-foot step. In some cases, the listed rules may also include limitations specific to that class or race using the ability (e.g. the additional 5-foot step may cost a swift or move action to perform).


Crawling

You can crawl 5 feet as a move action. Crawling incurs attacks of opportunity from any attackers who threaten you at any point of your crawl. A crawling character begins and ends the crawling movement with the Prone status condition.


Stepover

If a creature is 2 size categories or larger than a nearby enemy creature, it can effectively ignore that creature when moving (though moving still provokes attacks of opportunity as appropriate). By doing so, the larger creature can step over the smaller creature, ending its move either on or past the smaller creature. Neither creature is considered to be squeezing as a result of a Stepover, because the relative size differences are so great.

Note that a small enough creature can enter a larger creature's space using the Acrobatics rules for moving through an enemy space (Acrobatics check versus the creature's CMD + 5), but can only stop in the creature's space if the larger creature is at least 2 size categories larger.


Overland Movement

Characters covering long distances cross-country use overland movement. Overland movement is measured in miles per hour or miles per day. A day represents 8 hours of actual travel time. For rowed watercraft, a day represents 10 hours of rowing. For a sailing ship, it represents 24 hours.

  • Walk: A character can walk 8 hours in a day of travel without a problem. Walking for longer than that can wear him out (see Forced March, below).
  • Hustle: A character can hustle for 1 hour without a problem. Hustling for a second hour in between sleep cycles deals 1 point of nonlethal damage, and each additional hour deals twice the damage taken during the previous hour of hustling. A character who takes any nonlethal damage from hustling becomes fatigued. A fatigued character can't run or charge and takes a penalty of –2 to Strength and Dexterity. Eliminating the nonlethal damage also eliminates the fatigue.
  • Run: A character can't run for an extended period of time. Attempts to run and rest in cycles effectively work out to a hustle.


+ Table: Movement and Distance

Hustle 3 miles 4 miles 6 miles 8 miles
Run - - - -
One Day
Walk 12 miles 16 miles 24 miles 32 miles
Hustle - - - -
Run - - - -


  • Terrain: The terrain through which a character travels affects the distance he can cover in an hour or a day (see Table: Terrain and Overland Movement). A highway is a straight, major, paved road. A road is typically a dirt track. A trail is like a road, except that it allows only single-file travel and does not benefit a party traveling with vehicles. Trackless terrain is a wild area with no paths.

Plains x1 x1 x3/4

Tundra, frozen x1 x3/4 x3/4


  • Forced March: In a day of normal walking, a character walks for 8 hours. The rest of the daylight time is spent making and breaking camp, resting, and eating. A character can walk for more than 8 hours in a day by making a forced march. For each hour of marching beyond 8 hours, a Constitution check (DC 10, +2 per extra hour) is required. If the check fails, the character takes 1d6 points of nonlethal damage. A character who takes any nonlethal damage from a forced march becomes fatigued. Eliminating the nonlethal damage also eliminates the fatigue. It's possible for a character to march into unconsciousness by pushing himself too hard.
  • Mounted Movement: A mount bearing a rider can move at a hustle. The damage it takes when doing so, however, is lethal damage, not nonlethal damage. The creature can also be ridden in a forced march, but its Constitution checks automatically fail, and the damage it takes is lethal damage. Mounts also become fatigued when they take any damage from hustling or forced marches.

Space and Reach

Space

All figures are considered to occupy a given amount of space on the battlefield. Creatures of size Medium and Small take up one 5 foot square. Smaller creatures take up a smaller space: Tiny creatures take up a 2 1/2 by 2 1/2 foot space, Diminutive creatures take up a 1 foot by 1 foot space, and Fine creatures, no matter how tiny, are defined to take up a 1/2 foot by 1/2 foot space.

This means that small creatures can effectively fit multiple creatures into a 5x5 square. The space of smaller creatures were carefully chosen such they neatly "pack" into a 5x5 square. Thus, 4 tiny creatures fit into a five foot square, 25 Diminutive, and 100 Fine creatures could fit into a five foot square. For practical reasons, it is recommended that no more than four creatures be allowed into one space, no matter how tiny.

On the flip side of the coin, big creatures take up more space on the battlefield.

A Size Large creature requires a space 10 feet by ten feet to function without squeezing. A Size Huge creature requires a space 15 feet by 15 feet to function without squeezing. A Size gargantuan creature needs a space 20 feet by 20 feet. A Colossal creature requires a space 25 feet by 25 feet to remain unsqueezed.

Note that creatures can be larger than Colossal, but it is recommended that all figures, no matter how large, be represented by figures with a base no larger than 5x5.


Reach

Reach is how far away a figure can attack another figure with a melee weapon or other melee attack.

Size Medium and Small creatures have a reach of five feet: Namely, they can attack into and thus threaten all squares adjacent to their space.

Size Tiny and smaller figures have no effective reach: They cannot reach into adjacent squares far enough to effectively attack, and thus threaten. For very tiny creatures, they must enter a larger creatures square in order to attack and threaten it. Entering another hostile creatures space requires an Acrobatics roll, no matter the size difference, unless you are the larger creature and you are big enough to perform a Stepover.

Note that a creature always has Reach to all portions of its own space, and therefore can threaten all squares that are within it's space.

Large creatures typically have a longer reach. This is not written in stone, however, and every monster should be referred to in their writeup for what their reach is and how they threaten.

As a rule of thumb, creatures have a reach equal to the side of their space, IE, Large creatures reach ten feet, Huge creatures reach 15 feet, Gargantuan creatures reach 20 feet, and Colossal creatures reach 25 feet.

Flanking

External (Traditional) Flanking

You create a flank state any time you have maneuvered on the battlefield in such a way as to inconvenience your opponent due to the threatening actions of yourself and your allies. Flanking is the most common way in which teamwork with your friends provides you with a tangible in-game benefit.

Flanking only counts for melee attacks within your threatened area. If you do not threaten, you cannot flank or gain benefits from a flank. In order to threaten, you must be proficiently wielding a weapon capable of doing lethal damage in one or more of your hands, and able to perceive the target in some way. Some classes, feats, and racial abilities may present other ways to threaten squares.

When making a melee attack, you get a +2 flanking bonus if your opponent is threatened by another enemy character or creature on its opposite border or opposite corner.

A size Medium or smaller figure has four border squares and four corner squares. The Border squares are the full-edge squares, and the corner squares are the ...er... corner...squares.

A size Large figure has eight border squares (two on each edge) and four corner squares. Any border square on a given side provides flanking to any of the border squares on the other side. Corner squares are of course, the same.

A Size Huge figure (3x3 squares) has twelve border squares (three per edge). A size Gargantuan figure (4x4 squares) has sixteen border squares. A size Colossal figure (5x5 squares) has twenty border squares.

In all cases, any border square provides flank to any other border square, as long as the other border square is on the opposite side of the figure.

Only a creature or character that threatens the defender can help an attacker get a flanking bonus.

Creatures with a reach of 0 feet can't flank an opponent because they don't threaten adjacent squares, only their own internal square.


NOTE 1: Corner squares ONLY flank with the opposite corner squares. Yes, a corner square flank is not as 'good' as a border square flank.

NOTE 2: If a flanker takes up more than 1 square, it gets the flanking bonus if any square it occupies counts for flanking. This may allow a larger figure to threaten both a side and a corner of an enemy.

NOTE 3: If a single square contains more than one figure, and you establish a legal flank to that square, you have all of the figures in that square flanked and gain the flanking bonus against them all.

NOTE 4: Creatures with reach (or reach weapons) don't necessarily have to be adjacent to a creature they're attempting to flank. However, to determine whether they are flanking, they must still be able to trace a line from any corner of their own space to any corner of an ally's space who is also threatening the target creature. Only if this line passes through opposite borders (or opposite corners) of the creature they are attempting to flank, is it a successful flank. As with normal flanks, a line that only passes through adjacent borders of a target creature, or only passes directly along a target creature's border, does not grant a flank. Note that size Large or larger creatures with reach can start this line from any corner of any square they occupy.

Internal Flanking

In cases where there are very large size differences between foes on the field (i.e. 2 size categories or more), it is possible for smaller foes to be 'underneath' a larger figure. If the size difference is large enough to allow this, then neither figure is considered to be squeezing.

A Size Huge creature can share spaces with size Medium creatures.

A Size Gargantuan creature can share spaces with size Large creatures and smaller.

A Size Colossal creature can share spaces with size Huge creatures and smaller.

In all cases, for a smaller creature to enter a larger creature's space requires an Acrobatics roll. However, a larger creature can simply declare that they are performing a Stepover and move right over top of or past a smaller creature, if they are two sizes larger or more.

If a small enough creature is sharing a space with a larger creature, neither is squeezing. The smaller creature can gain internal flanking against the larger creature if he has an ally on any of the larger creature's border or corner squares, or an ally that is also sharing the space of the larger creature.

The larger creature flanks the smaller internal creature if any of the larger creature's allies can get adjacent to the smaller creature.

A creature with a Burrowing speed can tunnel through sand, loose soil, or gravel, but not through stone. Using Burrowing requires only as much concentration as walking, so the creature can attack or cast spells normally. The burrowing creature cannot charge or run. Loose material collapses behind the creature 1 round after it leaves the area. Burrowing does not give the creature the ability to breathe underground, so when passing through loose material, the creature must hold its breath and take only short trips, or else it may suffocate.

Attacks of opportunity against creatures with burrowing rely on the attacking creature's ability to draw line of effect to the square the burrowing creature just left. That is, if the burrowing creature is on the surface, and burrows into the ground, leaving a threatened square, the attacker probably has line of effect and can therefore make an attack of opportunity. However, passing under a creature while burrowing probably does not provoke attacks of opportunity, as the would-be attacker probably can't draw line of effect into the ground (unless he also has a Burrow speed, for example).


Earth Glide

A creature with Earth Glide can tunnel through dirt, rock and other non-magical ground materials. A creature with Earth Glide can make charges while burrowing, but cannot use the 'run' action while burrowing. Creatures with Earth Glide frequently leave behind tunnels that other creatures can use (either because the material they tunnel through is sturdy or because they are dislocating the materials somehow when burrowing); see the individual creature descriptions for details.

Attacks of opportunity against creatures with burrowing rely on the attacking creature's ability to draw line of effect to the square the burrowing creature just left. That is, if the burrowing creature is on the surface, and burrows into the ground, leaving a threatened square, the attacker probably has line of effect and can therefore make an attack of opportunity. However, passing under a creature while burrowing probably does not provoke attacks of opportunity, as the would-be attacker probably can't draw line of effect into the ground (unless he also has a Burrow speed, for example).


Climb

Lesser Climb

A creature with lesser climb has a +8 racial bonus on all Climb checks. The creature must make a Climb check to climb any wall or slope with a DC higher than 0, but it can always choose to take 10, even if rushed or threatened while climbing. The creature retains its Dexterity bonus to Armor Class (if any) while climbing, and opponents get no special bonus to their attacks against it. If a creature with a lesser climb speed chooses to make an accelerated climb as a move action, it moves at double its climb speed (or at its land speed, whichever is slower) and makes a single Climb check at a –5 penalty. If it fails this check, it falls back to its starting position, wasting the move action. A creature with lesser climb cannot use the run action while climbing.


Greater Climb

A creature with greater climb can climb and travel on vertical surfaces or even traverse ceilings with ease. The creature must at least one hand free to climb in this manner. The creature gains a +8 bonus on Climb skill checks; furthermore, it need not make Climb checks to traverse a vertical or horizontal surface (even upside down). A creature with greater climb retains its Dexterity bonus to Armor Class (if any) while climbing, and opponents get no special bonus to their attacks against it. A creature with greater climb cannot use the run action while climbing.


Fly

Lesser Flight

A creature with lesser flight can fly as a move action. It can ascend at half speed and descend at double speed, and its maneuverability is good.

Lesser flight requires only as much concentration as walking, so the subject can attack or cast spells normally. The creature can charge but not run, and it cannot carry aloft more weight than its maximum load, plus any armor it wears. The creature gains no bonus on Fly skill checks. To perform any maneuvers in the air, such as hover, the creature must make Fly skill checks. Any skill checks which are failed result in the creature losing altitude equal to its speed and losing the move action. If the lost altitude results in the creature landing on the ground, the creature lands on the ground, taking no damage.

If a creature with lesser flight is knocked prone, immobilized or denied enough of its actions that it cannot voluntarily move from its starting space, it falls out of the sky. (Note: it doesn't have to move, it just has to be able to move if it wanted to.) The creature immediately loses a number of feet of altitude equal to its fly speed. If this results in the creature landing on the ground, it lands and takes no damage. If the creature is still above the ground, the loss in altitude is subtracted, and then the creature falls the remaining distance to the ground, taking falling damage.

  • Falling Damage: Creatures that fall take 1d6 points of damage per 10 feet fallen, to a maximum of 20d6. Creatures that take lethal damage from a fall land in a prone position.

As a general rule of thumb, creatures with lesser flight cannot take falling damage from failing actions they initiated. Instead, they lose altitude until they land. However, if they are acted upon in such a way as their flight is disrupted, they can take falling damage, but always reduce the height of the falling damage by their fly speed.


Greater Flight

A creature with greater flight can fly as a move action. It can ascend and descend at normal speed and its maneuverability is perfect.

Greater flight requires only as much concentration as walking, so the subject can attack or cast spells normally. The creature can charge but not run, and it cannot carry aloft more weight than its maximum load, plus any armor it wears. The creature gains a +8 bonus on Fly skill checks and is not required to make Fly skill checks to perform any maneuvers in the air, such as hover.

If a creature with greater flight is knocked prone, immobilized or denied enough of its actions that it cannot voluntarily move from its starting space, it falls out of the sky. (Note: it doesn't have to move, it just has to be able to move if it wanted to.) Regardless of altitude, it floats to the ground, taking no falling damage.

A creature with greater flight never takes falling damage, even if knocked unconscious or denied all actions. Instead, it floats quickly to the ground. Of course, if it is transformed into something which no longer has greater flight (such as stone, or a bunny) all bets are off.


Swim

A creature with a swim speed can move through water at its indicated speed without making Swim checks. It gains a +8 racial bonus on any Swim check to perform a special action or avoid a hazard. The creature can always choose to take 10 on a Swim check, even if distracted or endangered when swimming. Such a creature can use the run action while swimming, provided that it swims in a straight line.


Teleport

Some creatures can teleport natively as a move action. This is not the same as casting a spell such as Dimension Door, since it does not require the creature to cast, concentrate or otherwise engage in prestidigitation. Teleportation is the act of moving instantly between two spaces without crossing the intervening space. A creature with teleport must be able to see his destination in order to teleport. Note that line of effect is not required, so a creature can teleport through a portcullis, or over a bottomless chasm. The distance of a teleport is measured using the straightest line between the starting point and the desired destination point.

Creatures with a teleport speed will never teleport into a solid object. If their destination somehow becomes filled with solidity (or they are seeing an illusion which makes them think their destination is safe), they are instead shunted to the first unoccupied space along the path they teleported. If all spaces between their starting space and their destination space are solid, the teleport fails and the move action is wasted.

Teleportation does not provoke attacks of opportunity from nearby enemies, either from leaving the starting square or from appearing in the destination square.

A creature with a teleport speed that attempts to teleport into open air will fall to the ground immediately at the end of their turn. Because the falling only occurs when its turn ends, a creature with a teleport speed could choose a mid-way point in mid-air for one teleport, then take a second move action to make another teleport to a spot on safe ground. Similarly, a teleporting creature could teleport up to a flying creature and attack it, assuming it was willing to suffer the falling damage afterwards. (See Falling below for details.)

A creature with a teleport speed cannot charge or run with the teleport movement action. However, creatures with a teleport speed may take feats as though they were able to cast Dimension Door, some of which allow them to perform charge actions and other fun things.


Special Movement Rules

Encumbrance

If your character is carrying enough weight, their movement will be slowed. There are three categories of encumbrance, Light, Medium, and Heavy. The pound value of these categories are determined by the character's Strength score on the Carrying Capacity Table.

Each of the encumbrance categories affects your movement exactly as the armor of the same name category. Namely, Medium encumbrance reduces your movement by five feet if your base move is above 20 feet, and Heavy encumbrance reduces your movement by ten feet if your base move is above 20 feet and five feet otherwise. Note that these movement penalties stack!

For example: Wearing heavy armor and carrying enough weight to place you in Medium encumbrance reduces your movement by 15 feet if your base move is above twenty feet or ten feet if your move is twenty feet or below.

If these penalties reduce your base move to zero, you can no longer use a move action to move. You must now use a standard action to move five feet, and can move no more than five feet per round unless you use an action point to take two standard actions in a round.

In addition to the above effects, weight-based encumbrance lowers your speed when you take a Run maneuver. Medium weight encumbrance lowers your Run multiplier to x4. Heavy weight encumbrance lowers your Run multiplier to x3.


Squeezing

If you end your turn in the same space as another creature, and each of you normally takes up the full space, you are both considered to be squeezing. Squeezing can only occur if the two creatures sharing a space both agree to allow that to happen, or one creature is unable to prevent it (such as being unconscious or stunned). Even if one of the two creatures sharing a space is prone, both creatures are treated as squeezing. However, if one of the creatures is dead, the squeezing rules do not apply. Instead, the dead creature is treated as rough terrain (GM's may elect to ignore the 'dead creatures are rough terrain' rule, since it's kind of annoying to keep track of).

Squeezing can also occur when a character tries to fit through a space that is designed for creatures one size category smaller than he is, but wider than his head. No creature can pass through a space narrower than its head (unless it has some special ability allowing it to break this rule). An example of a narrow space might be a door designed for size-small creatures. A medium-sized creature could fit through there, but their ability to attack or defend themselves while doing so would be greatly impaired. A large-sized creature couldn't fit through the size-small door at all.

While squeezing, a creature suffers a -4 penalty to attack rolls and a -4 penalty to AC.


Falling

Creatures that fall take 1d6 points of damage per 10 feet fallen, to a maximum of 20d6. Creatures that take lethal damage from a fall land in a prone position.

If a character deliberately jumps instead of merely slipping or falling, the damage is the same but the first 1d6 is nonlethal damage. A DC 15 Acrobatics check allows the character to avoid any damage from the first 10 feet fallen and converts any damage from the second 10 feet to nonlethal damage. Thus, a character who slips from a ledge 30 feet up takes 3d6 damage. If the same character deliberately jumps, he takes 1d6 points of nonlethal damage and 2d6 points of lethal damage. And if the character leaps down with a successful Acrobatics check, he takes only 1d6 points of nonlethal damage and 1d6 points of lethal damage from the plunge.

Falls onto yielding surfaces (soft ground, mud) also convert the first 1d6 of damage to nonlethal damage. This reduction is cumulative with reduced damage due to deliberate jumps and the Acrobatics skill.

A character cannot cast a spell while falling, unless the fall is greater than 500 feet or the spell is an immediate action, such as feather fall. Casting a spell while falling requires a concentration check with a DC equal to 20 + the spell's level. Casting teleport or a similar spell while falling does not end your momentum, it just changes your location, meaning that you still take falling damage, even if you arrive atop a solid surface.


General Collisions Rules

Adventurers frequently bash themselves into things through various circumstances. For example, a Barbarian sees a Drow Matriarch with no escorts, so he charges her full speed...only to find the Force Wall in the way. He smashes into the wall full speed, but how much does that hurt? This is treated as a collision, which is a more general case of Falling damage. In this case, since he was in a Charge maneuver which reduced his armor class, he was not considered to be moving cautiously. As a result, he takes 1d6 of damage per ten feet of his speed at the moment of the collision. If he has a base speed of 50 feet and a Haste spell to raise his speed to 80, then he takes 8d6 from this collision. Ouch. It's made even worse my the Matriarch laughing....

If he was not moving in a precipitous manner, ie, a normal move at his base speed, he would only take 1d6 per thirty feet of his movement at most. In many cases, such a result would cause no damage at all, since that is the reward for moving cautiously. The Game Master adjudicates all cases of collision damage, and are encouraged to keep it fun and interesting, and maybe even show a little mercy.

Collisions are used for many things, such as being swept away down a boulder-strewn gully by a flash flood, or being run over by that huge round stone that rolled out of the ceiling in that lost temple, or when that nobles carriage runs wild down the streets, or even when the hapless adventurer is being dragged along the ground behind a racing horse. Any time an object bangs into an adventurer in an uncontrolled and violent fashion, this can be resolved using these collision rules, which are that the adventurer takes 1d6 per ten feet of speed, and if it's lethal damage, they are knocked prone by the experience.

Note, being dragged by a horse really sucks, you want to get out of that as soon as possible.


Falling into Water

Falls into water are handled somewhat differently. If the water is at least 10 feet deep, the first 20 feet of falling do no damage. The next 20 feet do nonlethal damage (1d3 per 10-foot increment). Beyond that, falling damage is lethal damage (1d6 per additional 10-foot increment).

Characters who deliberately dive into water take no damage on a successful DC 15 Swim check or DC 15 Acrobatics check, so long as the water is at least 10 feet deep for every 30 feet fallen. The DC of the check, however, increases by 5 for every 50 feet of the dive.


Falling Objects

+ Table: Damage from Falling Objects
Object Size Damage
Tiny 1d6
Small 2d6
Medium 3d6
Large 4d6
Huge 6d6
Gargantuan 8d6
Colossal 10d6


Just as characters take damage when they fall more than 10 feet, so too do they take damage when they are hit by falling objects. Note that falling object damage is resolved differently from collisions, because falling objects are typically thrown by a bad guy, rather than being environmental hazards.

Objects that fall upon characters deal damage based on their size and the distance they have fallen. Table: Damage from Falling Objects determines the amount of damage dealt by an object based on its size. Note that this assumes that the object is made of dense, heavy material, such as stone. Objects made of lighter materials might deal as little as half the listed damage, subject to GM discretion. For example, a Huge boulder that hits a character deals 6d6 points of damage, whereas a Huge wooden wagon might deal only 3d6 damage. In addition, if an object falls less than 30 feet, it deals half the listed damage. If an object falls more than 150 feet, it deals double the listed damage. Note that a falling object takes the same amount of damage as it deals.

Dropping an object on or throwing and object at a creature requires a ranged touch attack. Such attacks generally have a range increment of 20 feet. If an object falls on a creature (instead of being thrown), that creature can make a DC 15 Reflex save to halve the damage if he is aware of the object. Falling objects that are part of a trap use the trap rules instead of these general guidelines.


Difficult Terrain

Some terrain is too tricky to move through at normal speed. Such terrain is called "difficult" though this can encompass many scenarios: obstacles, slippery or unstable footing, steep slopes, etc. When moving through difficult terrain, each square moved into counts as two squares (10 feet), effectively reducing the distance that a character can cover in a move. Characters cannot run or charge through difficult terrain, nor can they take 5-foot steps.


Nearly Impassable Terrain

Sometimes the terrain is so difficult that you must clamber over it on hands and knees, rather than just carefully navigating it. Examples include junk-strewn rooms, vine-choked jungles, or waist-deep bogs. A creature wishing to move through such terrain must use a full-round action to move 5 feet. This is not treated as a 5-foot step and does provoke attacks of opportunity. Creatures attempting to move through nearly impassable terrain cannot run or charge through such terrain, nor can they maintain any stances, including stealth.

Note that nearly impassable terrain is not the same as impassable terrain, such as walls, locked doors or closed portcullises. Impassable terrain is considered to also be blocked if the space is filled with a solid object such a wall, pillar, statue, etc.

Some nearly impassable terrain may allow an acrobatics or climb check to move more than 5 feet per full-round action, at the GM's discretion. As a general rule, however, spending a full round to move 5 feet does not require any sort of skill check.


Impassable Terrain

Impassable terrain is terrain it is impossible to move into without such things as incorporeal powers, burrowing, earth glide, extremely small size, extremely large size, etc. Note that teleport can move through impassable terrain as long as line of sight and line of effect rules are satisfied. Further note that many types of impassable terrain also block line of sight and/or line of effect. The DM adjudicates any unusual cases. Examples of impassable terrain include solid walls, natural stone or dirt, doors, shutters, gates, and portcullises, roofs and roads, pillars, columns, and statues, etc. In addition, many environmental hazards are classed as impassable terrain. Lava, for example, is usually impassable because of the extreme heat and the fact that it is extremely difficult to walk upon a liquid surface, no matter how dense. (Note that it is possible to defeat this with epic acrobatics.)

Note that even though many abilities exist which may defeat impassable terrain, in all cases a referee may declare that terrain is impassable by any means, and such declarations stand. In general, DM's should strive to avoid situations which call for rulings, but occasionally it is necessary for smooth gameplay.


Cutting Corners

On a square grid, in clear terrain, a character may move into any of the eight squares adjacent to their current square. Moving through an edge is considered "moving straight", and moving through a corner is considered to be "cutting the corner". Cutting a corner may or may not be possible, depending on the nature of any items that fill a square. If the item completely fills the square, such as the corner of a dressed stone hallway, the edge of a door in a flat wall, or a square pillar that fills the space completely, then you cannot cut a corner to skim past that space. If the item fills the space such that you cannot occupy the space (without being incorporeal or other means), but, does not completely fill the space, then you can still cut the corner to move diagonally past it. Examples are large trees, round pillars, most natural stone walls, etc.


Blocked Squares

A blocked square is one that is occupied by an object large enough to interfere with other objects moving into that square. This mainly applies to large weaponry that requires a great deal of space to use. All walls create blocked squares, as do trees and pillars. Low objects such as chests, tables, thrones, caskets, railings, and the like, generally impede or even prevent movement, but do NOT create a blocked square, since the weapon in question can be swung above the low object without trouble.

A blocked square is usually considered impassable terrain, but not always. An example is a square next to an open stone staircase, a balcony, stepped floors, sinkholes and pits, etc. The DM should rule on all unusual cases.


Occupied Squares

An occupied square is any square which falls within the allocated space for a creature's Size. Medium and smaller creatures Occupy one square. Large creatures occupy 4 squares, huge creatures occupy nine squares, gargantuan creatures occupy sixteen squares and colossal creatures occupy twenty-five squares. Note that occupied squares are NOT blocked, impassable, nearly impassable, or even difficult terrain simply because they are occupied. To enter another creatures squares is not simple, but is possible. Refer to the sections on squeezing, stepover, acrobatics, internal flanking, threatened area, etc.



Threatened Area

To threaten an area, a creature must be capable of inflicting harm upon a foe in a legal fashion as a reactive action, namely, be able to take attacks of opportunity. Usually this requires a creature to be proficiently wielding a melee weapon or possess natural attacks. Ranged attacks almost never threaten squares, and if they do, require special abilities or feats to do so.

Creatures who can make legal attacks of opportunity threaten all spaces they have Reach to and all spaces they occupy. Yes, moving around inside the space of a hostile creature provokes attacks of opportunity, so be careful when seeking that internal flank.



Forced Movement

Most forced movement is handled via the Combat Maneuver system, but there is an added class of "automatic" forced movement which is occasionally available via spells, class abilities, monster powers, etc. All forced movement allows the attacking creature to move an enemy one or more squares from its current location.

It is not normally possible to resist forced movement at all, unless you have a special power or ability which specifically opposes such movement. No matter how the forced movement is inflicted, either by Combat Manuevers, spells, class abilities, etc, all forced movement is resisted by any special powers or abilities that resist forced movement. Such resistance applies after CMB vs CMD rolls are resolved. Note that forced movement reductions stack, so if a character has a means of reducing forced movement from more than one source, such as a class ability or magic item, the character uses the sum of the reductions offered.

Forced movement ignores the penalties to movement for rough terrain, but must be into unoccupied squares of a size and shape equal to the creature being forcibly moved. If there are no unoccupied squares available for the creature to be legally forced into, the forced movement does not take place.

A creature subjected to forced movement may, at any time during the forced movement, elect to fall prone, immediately ending the forced movement. This tactic is especially useful to avoid being forced into a hazardous square, such as a pit or a trap. Creatures which are immune to prone can still use this option and are not prone afterwards, making them very nearly immune to forced movement. Monsters with roles that render them immune to status conditions can use this tactic, for example. Tank role monsters are immune to all status conditions, so they can use the 'fall prone' election to stop forced movement at any time, and then are not prone.

Forced movement never provokes attacks of opportunity, unless there is a feat or ability in play which pierces this.


Push

A Push is forced movement in which a creature is moved by an attacker in a path away from the attacker. Each square of this forced movement must be further away from the attacker's square(s) than the square being exited. If any squares in the desired path are blocked or occupied by any creatures (friend or foe) the push ends in the square prior to this obstruction.


Pull

A Pull is forced movement in which a creature is moved by an attacker in a path toward the attacker. Each square of this forced movement must be closer to the attacker's square(s) than the square being exited. If any squares in the desired path are blocked or occupied by any creatures (friend or foe) the pull ends in the square prior to this obstruction.


Slide

A Slide is forced movement in which a creature is moved by an attacker in any path the attacker wishes. If any squares in the desired path are blocked or occupied by any creatures (friend or foe) the slide ends in the square prior to this obstruction.


Distance, Movement, and Area of Effect

Accounting for distance and movement is a complex topic, and large amounts of thought went into this. For these variant rules, Pathfinder's Distance, Movement, and Area of Effect rules are the 'standard'. Namely, measure all movement in squares, face-to-face moves are 1 for 1, and diagonal moves are 1, then 2, then 1 for 1. Area of effects are represented by templates and precisely defined.

This approach is simple, but is not very flexible and introduces several issues. For example, there is no template for a 25 foot cone, so how do you determine the area of such a custom area of effect? Why is the template for a sixty foot cone actually eighty feet wide? How do you determine the exact size of a sixty foot cone that has been doubled in size by a meta-magic feat? What about a sixty foot radius circle? Why is the area of a sixty foot line cut in half if it is laid down in a diagonal?

Moreover, these variant rules introduce several high-maneuverability classes, namely, the prowler, the monk, and the brawler. In addition to the maneuver classes, several classes may gain area of effect attacks, such as epic bards and fighters, and of course the spell-casters. In order to make play smoother and more enjoyable in such a fluid environment, it is strongly recommended that the following variant rules be used for measuring distance, movement, and area of effects.

ALL distances and movement are counted as "1 for 1." There is no penalty for moving in diagonal lines. This has the effect of greatly simplifying the work of determining ranges and allows high-maneuverability classes to play much faster.

ALL areas of effect are simplified.

Templates are no longer used for circles or cones. The area of effect for all common cones and circles are reduced to squares, based upon the conversions below. This simplifies placing AOE's considerably, and allows custom sizes or widened spells to be used easily.


Placement Rules

No-range attacks (usually cones) are placed by ensuring that any square of the AOE must have one point of adjacency, either a side or a corner, with one of the attacker's squares. For example, a size Medium wizard uses Burning Hands. This spell has a fifteen-foot-cone area of effect. In these rules, the cone template is not used, and instead the Area of Effect is converted to a three by three square. The location of the effect of the spell must be adjacent to either a side or a corner of one of the caster's squares. Since the wizard is size Medium and thus has only one square, the Burning Hands AOE must be adjacent to either a side or a corner of that square.

A size Huge dragon breathing a sixty foot cone of fire is resolved as follows: A size Huge creature occupies a three by three square. A sixty foot cone is defined as an 8x8 square. The 8x8 square of the area of effect must be placed so that it is 'touching' any edge or corner of the 3x3 square of the dragon's space.

Ranged area of effect attacks are not determined by adjacency to the attacker's square. Instead, they are counted out from a central target point. All 'odd number' areas of effect are centered upon a target square. All 'even number' areas of effect are centered upon an intersection 'targeting cross-hair' formed by four squares.


Conversion of Areas of Effect

Many of the larger areas of effect have been reduced in size to balance the fact that corners are no longer being cut out by the old 3:2 diagonal rules. The total affected area is still usually greater under these variant rules. This reduction also allows for simplification of the Widen Spell metamagic feat, which simply doubles the listed axis values. For example, a 30-foot cone with Widen Spell applied grows from a 5x5 square to a 10x10 square.


Line Areas of Effect

To determine which creatures are struck by a line attack, choose the origin square (any square adjacent to the caster) and any target square within range, and draw a straight line between the center of the two squares. The target square may be closer than the line's maximum range but it may not be further. Note that the line's range is not shortened by choosing a square closer than the maximum range; the effect simply passes through that square to its maximum range. Any square that the line crosses, even partially, is considered to be within the line's area of effect. If there is some doubt that the line has actually passed through a square, rather than just nicking its edge or corner, the GM should generally rule conservatively, (i.e. the line doesn't cross that square), since lines are intended to be somewhat limited in area of effect.


Cone Areas of Effect

    • 15 foot cone becomes a 3x3 square around a target square
    • 30 foot cone becomes a 5x5 square around a target square
    • 60 foot cone becomes an 8x8 square around a target intersection point


Radius Areas of Effect

    • 5 foot radius becomes a 2x2 square around a target intersection point
    • 10 foot radius becomes a 4x4 square around a target intersection point
    • 15 foot radius becomes a 5x5 square around a target square
    • 20 foot radius becomes a 7x7 square around a target square
    • 30 foot radius becomes a 9x9 square around a target square
    • 40 foot radius becomes a 12x12 square around a target intersection point


Three Dimensional Movement

For three dimensional movement, it is strongly recommended to use the above variant rules for counting movement, distance, and areas of effect. The reason is simple: when calculating the range between two objects at different altitudes, using the old rules required trigonometry or guesswork. In the 1 for 1 counting rules, the different altitudes can be ignored, as long as the difference in altitude is equal to or less than the difference between the figures.

For example, a ranger wants to shoot an orc who is hiding thirty feet high in a tree. In these rules, as long as the ranger is thirty feet or more away from the base of the tree, the range is simply defined as the range to the tree's square. If the ranger is closer than thirty feet to the base of the tree, the range is simply thirty feet, no matter where he moves around the base of the tree. This is a tremendous simplification and makes gameplay much faster and smoother.

For this reason, it is strongly recommended that referees enforce 'altitude ceilings' in three dimensional encounters. This is readily accomplished inside large buildings and caves, etc. Outdoors, it is usually simplest to abstract 'up' and 'down', so that the maximum distance between two combatants is always defined as the distance between their figures on the map. Alternatively, the referee may rule by fiat that cloud cover, or a tree canopy, or hazardous smoke/vapor, etc, limits the maximum altitude at which combat is possible.

If these rules are followed, then range and area of effect in three-dimensional movement is no different than in 2-dimensional movement. All squares are visualized as cubes. Moving from cube to cube may be done from face-to-face, or edge to edge, or corner to corner. All moves and ranges are counted as 1 for 1.

As a corollary to this, when three dimensional movement is being used, all characters are considered to be represented as cubes in space, not squares on the map. The cube is a number of squares high equal to the number of squares per side of the figure's size.

Thus, a small or medium creature occupies a cube five feet on a side. A large creature occupies a cube ten feet on a side. A huge creature occupies a cube fifteen feet on a side. Larger creatures continue using this same progression. For game balance reasons, the same number of smaller creatures will fill a cube as fill a same size square. Two Small creatures may occupy a five foot cube without squeezing. Four tiny creatures fill a cube, etc. This rule is to prevent dozens and dozens of enemies from filling a single space.

This system makes it much easier to accommodate feats of derring-do. For example, how high up is a Huge Elephant's back? Fifteen feet! So if a player character jumps to the back of an elephant, that is how far away they are from the ground. The bottom of the character's cube rests upon the top of the elephants cube, and reach and range are determined accordingly.

All cubes that border either a side, edge, or corner are considered adjacent in three dimensional movement.

Reach now affects all adjacent cubes, including the one above your head (and beneath your feet) as well as the ones above and below your adjacent squares.

Areas of effect, defined above as squares, are simply counted as cubes in three dimensional movement. Odd-sized cubes are centered upon a target cube, even-sized cubes are targeted upon the three-axis intersection of eight cubes.
