Acid Bucket Trap
A faint, acrid smell wafts through the half-open door.
A bucket filled with acid balances precariously on top of the door. Opening the door triggers a Critical Failure.
Exploration. A Perception check or an examination of the floor reveals pockmarks where the acid has eaten away the stone (or, if the Narrator prefers, the footprints of small creatures that have slipped through the doorway without opening the door further). An Investigation check or an examination of the top of the door reveals the acid-filled bucket.
Keeping Clear. Magic (such as the mage hand cantrip), a long pole, or a similar item can be used to trigger the trap from a distance, resulting in a Success.
- A Medium creature can make an Acrobatics check to slip through the partially open door. A Small creature automatically succeeds on the check.
- A Sleight of Hand check removes the bucket from the door.
Potential Outcomes
Critical Failure or Failure. The bucket spills its contents across the threshold. Each creature within 5 feet of the door when the bucket falls makes a Dexterity saving throw .
On a failure, the creature takes 5 (2d4) acid damage, plus an additional 5 (2d4) acid damage at the end of its next turn. A creature can use an action to wipe off the acid, preventing the damage on the second turn.
Success. The bucket spills acid into an unoccupied space within 5 feet of the door.
Critical Success. The trap is not triggered, and the creature obtains the bucket of acid, which can be thrown up to 20 feet as an improvised ranged weapon. A target hit by the bucket takes 2d4 acid damage, plus an additional 2d4 acid damage at the end of its next turn.
