Rolling Boulder Trap (CR 10)

Rolling Boulder Trap CR 10

Type mechanical; Perception DC 25; Disable Device DC 20

Trigger location; Reset repair


This trap is typically placed in a 10 foot wide passageway of an ancient tomb and is set to crush those that set it off or seal the intruders inside. The boulder rolls for 40 feet, crushing everyone in the hallway that fail the Reflex save and slams into the wall with the only doorway out sealing inside all those still alive. This prevents any surviving grave robbers from leaving and any future grave robbers from entering. Moving the boulder enough to allow a medium sized creature to slip through the doorway requires 3 successful DC 35 Strength checks. Trap cost: 7,500 gp. Construction DC: Craft (traps) 25.


Rolling boulder (12d6 damage, DC 25 Reflex negates); multiple targets (all targets in a 10-ft. x 40-ft. area)


Skill Craft (traps) DC 25; Cost 7,500 gp
