Stance

An effect type. When a character uses a stance power, the character assumes a stance of some kind.

Duration: A stance lasts until the character assumes another stance or until the character falls unconscious or dies. A stance also ends at the end of the encounter, unless the stance can be assumed at will.

One per Turn: A character can assume no more than one stance per turn.
