Clouder

The north wall of room 7/22 writhes more than the other plant walls on the floor. If an individual walks across the room, fully visible, briar vines snake from the wall and attempt to grab them. On a successful Save vs Paralysis, the adventurer avoids the vines. On failure, they take piercing damage and are pulled into the briar wall. From there, they emerge from another briar wall of the GM's choice, with a good default choice being the central stairwell for the floor.
