Effect Rolls boulder, causes damage

A rolling boulder trap is a trap that can cause a boulder to roll towards you and hit you.

Effects

The trap has two parts. The actual trap is a switch which, when activated by stepping on it, sets a nearby boulder rolling toward you. The path between the boulder and the trap must be clear,[1] though the boulder will pass through some dungeon features like fountains. When it hits another boulder, it stops, and the other boulder begins moving. [2]

Being hit with the boulder deals you d20 damage.

Removal

Destroy the boulder, move it beside the trap, or move it out of line with the trap, then activate the trap; a boulder trap only activates if there exists a boulder on one of the two designated launch squares, and activating the trap when there is no suitable boulder will destroy it.[3][4]

Strategy

The existence of these traps can sometimes be inferred by an incongruously placed boulder in a room.
