Shadow Creature

'Shadow Creature' is a pattern that can be added to any creature that is a 'Shadowy' variant of a base creature, typically brought from the Plane of Shadows or other dark, insubstantial realm. Shadowy creatures look like their base creature, except they are vague and undefined, shrouded in clinging wisps of shadow-stuff, and even sort of translucent in direct light. A Shadow Creature uses all of the base creature's statistics and abilities except as noted below.

CR

Same as base creature +3.

Size and Type

The creature's Size does not change. It's Type remains the same but it gains the subtype Shadow.

Initiative Modifier

The creature's initiative modifier increases by +4.

Senses

All senses such as scent, tremorsense, keen hearing, etc are unchanged. In addition, all Shadow Creatures gain Blindsense with a range of thirty feet, giving them a +5 on Perception rolls to defeat Stealth and ignoring Invisibility.

Armor Class

No changes.

Hit Dice

Gain +3 hit points per hit die of their adjusted CR.

Defensive Ability

A Shadow Creature gains the following abilities, which may be added to their Bestiary entry:

Aura: - Aura of dim light. Shadow creatures are always shrouded in dim light, granting them 20 percent concealment and rendering precision damage impossible to inflict. Shadow creatures in full darkness create dim light within ten feet of their space. Shadow creatures in normal light lower lighting conditions to dim light within ten feet of their space. No natural or magical source of light or darkness overcomes this effect.

SR: - Same as Base Creature

Special Defenses: None

Immunities: Same as the base creature.

Weaknesses: Same as Base Creature, plus:

Vulnerable to light or positive energy damage.

Out of Combat

Same as base creature, except utterly, completely weird. Shadow creatures are noticeably recognizeable as their base creature, but skewed, odd, and wrong. They eat strange food, act in weird and unsettling ways, have strange and unsettling greetings and talk in a freakishly disjointed cadence. They are understandable and recognizable, just...wrong.

Speed

Same as Base Creature.

Melee Attacks

A Shadow Creature retains all the base creature's attacks and gains an untyped +3 hit with all attacks. However, a Shadow creature makes all of their attacks as touch attacks. If the base creature already had a touch attack, that attack is now made at a +3 untyped bonus to hit.

Damage

No change.

Space and Reach

No Changes.

Offensive Ability

No Changes.

Ability Scores

No changes.

Maneuver Offense and Maneuver Defense

Gain an untyped -5 penalty on Maneuver Offense, but also gain an untyped +5 bonus on Maneuver Defense.

Skills

The GM may add one skill for flavor, and should pick something weird and strange, like Profession: Flenser.
