Tar Pit
Level 9
Stealth DC 30 (expert)
Disable Survival DC 25 (expert) to disturb the surface and reveal the tar pit
Capture [Reaction]
Routine (1 action) On its initiative, the tar pit pulls down each creature within it, thick tar adhering to the creature's body. A creature that was submerged up to its waist becomes submerged up to its neck, and a creature that was submerged up to its neck is pulled under and must hold its breath to avoid suffocation. A creature in the tar pit can attempt a DC 33 Athletics check to Climb to either raise itself by one step (if it's submerged to its neck or full submerged) or to move 5 feet if it's submerged only up to its waist. On a critical failure, the creature is pulled down one step.
