Trapped Sarcophagus
Surely there must be something valuable inside.
Falling Doors. When the pressure plate is triggered, both doorways into the room are blocked by heavy stone doors, each weighing 2,000 lbs. The switch to raise them again is inside the sarcophagus.
Sarcophagus Lid. When the pressure plate is triggered, the lid explodes off in an intense gust of wind. Any creature on the pressure plate takes 4d10 bludgeoning damage and is knocked prone and pushed back 5 feet. A DC 15 Dexterity save halves the damage and avoids the other effects.
Trap. This trap can be detected by a passive Perception of 15 or with a Perception check to notice the plate. If the trap is not detected, it automatically triggers a critical failure.
- Even if the adventurers notice the trap, there are multiple parts to this puzzle. Rolling or sliding something heavy enough (30 pounds or more) onto the plate will safely trigger the lid portion, but the falling doors still drop without a successful DC 14 Engineering or thieves’ tools check to disarm them.
Potential Outcomes
Critical Failure: The adventurer who stepped onto the plate must roll to avoid the sarcophagus lid. Failure on the saving throw also causes a level of fatigue .
Failure: The adventurer who stepped onto the plate must roll to avoid the sarcophagus lid.
Success: The adventurer disarms the trap.
Critical Success: The adventurers disarm the trap but have the option to leave the trap active for someone else to deal with.
