Take a Seat! [reaction] Trigger A creature steps on the track; Effect The chair rockets forward along the track and slams into the triggering creature, dealing 3d8+15 bludgeoning damage. A creature who succeeds at a DC 22 Reflex save takes no damage and moves out of the chair's path into a random adjacent square not containing the track. A creature who fails this saving throw is knocked into the chair's seat and immediately captured by the armrests, becoming grabbed (restrained on a critical failure; Escape DC 26).
Reset The trap resets automatically over 2 rounds if the chair is unoccupied.
