Magic Trap

At-will, swift, touch; you create a magic trap in a touched, unoccupied square, choosing one trap effect from the Magic Trap list of your rank or lower. The trap triggers the first time a creature other than you enters the square, and then vanishes. It expires untriggered after 1 hour. You can have active traps equal to your Wisdom modifier (minimum 1); setting another when you are at the limit dispels your oldest trap. You can dismiss any of your traps as a free action.
