Rolling Stone Cylinder Trap
Level 6Hazard (Complex)Abilities
A lever at the top of the south tower is pulled
Effect A thick column of stone drops from above the gate, then uses crushing roll. The rolling stone cylinder trap rolls initiative.
Requirements The rolling stone cylinder is not Immobilized
Effect The rolling stone cylinder trap moves its Speed west along the bridge. Creatures it moves past or lands on take 5d6 bludgeoning damage and are forced to move west to the first available space (DC 27 reflex). Creatures who critically succeed at the Reflex save are not damaged but are still moved west. If the rolling stone tries to move into a non-creature obstruction, such as a wall or barricade, it deals bludgeoning damage
A 10-foot-long, 5-foot-thick column of stone thuds to the ground, just in front of the bridge. It immediately starts to roll down the bridge, quickly picking up speed.
