Devil's trap

Devil's trap is trap used on demons. Once in the trap, a demon cannot escape and their powers are nullified.

Effects
Like salt, demons can't escape once inside the trap. They can easily walk into one, but can't get out unless the circle is broken, and they cannot use their powers nor break the circle directly while within it. Despite this, the trap is a drawing, and if the drawing is in any way broken or altered, the trap will lose its power.
