Magic Missle Trap
A lever is rigged to activate when pulled that activates a magic imbued trap that casts magic missile at the target. The surface is covered with arcane symbols and writings.
Effect: One target, 13 (2d10) force damage
Trigger: lever, activates when the wrong lever is pulled.
Countermeasures: A successful DC 10 Intelligence (Investigation) check allows a character to deduce the trap's presence. A successful DC 10 Dexterity check using thieves' tools disarms the trap, disabling the trigger. Unsuccessfully attempting to pick it triggers the trap. Casting dispel magic (DC 14) will prevent the missiles from firing.
Catapult Trap
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 releases the spell stored within the trapped object. The object is covered in arcane symbols and writing.
Effect: +5 to hit (or DC 14) against one target, Casts Catapult centered on the triggerer
Trigger: lock trigger, activates when opened without the proper key.
Countermeasures: A successful DC 10 Intelligence (Investigation) check allows a character to deduce the trap's presence. A successful DC 10 Dexterity check using thieves' tools disarms the trap, disabling the trigger. Unsuccessfully attempting to pick the lock triggers the trap. Casting dispel magic (DC 14) on the trap will cancel the stored spell.
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) | 4 (1d4) | 5 (2d4) |
| Small (chest, lute) | 5 (1d6) | 10 (3d6) |
| Medium (barrel, chandelier) | 7 (1d8) | 17 (4d8) |
| Large (cart, 10x10 ft. window) | 10 (1d10) | 27 (5d10) |
