Piranha Tank
A trigger is hidden within a treasure chest's lock, or in something else that a creature might open. Opening the chest without the proper key opens the floor into a water tank filled with hungry piranhas. The floor is covered in rectangular panels, about 3x6' to camouflage the trap.
Effect: Targets all creatures within a 10 ft. square area, targets are dropped into a water tank filled with starving piranha which swarm and bite, dealing 23 (4d10) piercing damage each round.
Trigger: lock trigger, activates when opened without the proper key.
Countermeasures: A successful DC 15 Intelligence (Investigation) check allows a character to deduce the trap's presence. A successful DC 15 Dexterity check using thieves' tools disarms the trap, disabling the trigger. Unsuccessfully attempting to pick the lock triggers the trap.
The piranhas will eventually get full after they've consumed 2 full-sized bodies worth of meat. Freezing the water will kill the piranha and allow safe passage over top.Guillotine Blade
A door or chest is rigged to activate when opened, which drops a guillotine blade from a slit in the ceiling. There are slits in the ceiling camouflaged with vines or chains.
Effect: +12 to hit against one target, 24 (4d10) slashing damage
Trigger: door, activates when a door or chest is opened.
Countermeasures: Spotting the attached wire is a DC 15 Wisdom (Perception) check. A successful DC 15 Dexterity check using thieves' tools breaks the wire attached to the door harmlessly. A character without thieves' tools can attempt this check with disadvantage using any edged weapon or edged tool. On a failed check, the trap triggers.
Destroying Traps
Traps can be damaged and destroyed, sometimes to good or bad effect. Pipes containing fire or poison will rupture and spray over the area, while mechanisms can be rendered inoperable with enough force. Determine the HP and AC of your traps based on the tables below. Sometimes a fragile trap is more dangerous than a resilient one if destroying it will fill the corridor with acid.
| Substance | AC |
|---|---|
| Cloth, paper, rope | 11 |
| Crystal, glass, ice | 13 |
| Wood, bone | 15 |
| Stone | 17 |
| Iron, steel | 19 |
| Mithral | 21 |
| Adamantine | 23 |
| Size | HP (Fragile) | HP (Resilient) |
|---|---|---|
| Tiny (bottle, lock) | 3 (1d4) | 4 (2d4) |
| Small (chest, lute) | 1 (1d6) | 11 (3d6) |
| Medium (barrel, chandelier) | 2 (1d8) | 13 (4d8) |
| Large (cart, 10x10 ft. window) | 2 (1d10) | 34 (5d10) |
