 === Partial Concealment ===
-Partial Concealment gives the subject of a successful attack a 20% chance that the attacker missed because of the concealment. Make the attack normally &mdash; if the attacker hits, the defender must make a miss chance d% roll to avoid being struck. Multiple concealment conditions do not stack.
+A creature is considered to have partial concealment when the environment or circumstances make it difficult, but not impossible, to perceive the creature.  This can occur because the creature is within a dimly-lit area, and the enemy creatures use standard vision as their primary targeting sense, for example.  Another common occurrence of partial concealment is fog or some other Obscuring effect that interferes with line of sight.
+When a creature has partial concealment, any to-hit roll in which the d20 result is 6 or less on the die is treated as an automatic miss.  This is treated as though the natural die result was a 1.
+There is no separate roll for partial concealment &mdash; it is the same roll as the to-hit roll.  This means that creatures with particularly high armor classes (ACs) rarely gain any benefit from partial concealment, since a natural 6 on the die will nearly always miss them, even without partial concealment.
