Slamming Gate

A spring-loaded gate stands open and inviting, its mechanism wound tight behind the frame. Trip the wrong step and it snaps closed, trapping the unwary on the wrong side.

Slam Shut [Reaction]

The trap can be reactivated (or deactivated, if it's active) by flipping a lever hidden in the nearby wall. A character Searching the area finds it with a successful DC 18 Perception check.
