Trap Generator

Wind Trap

An area is warded with a detect magic spell. When magic is detected within the spell's radius the trap is triggered which activates huge fans that spin out a powerful gust of wind, pushing away intruders into other hazards. The walls are perforated or mesh and have spikes.

Effect: Targets all creatures within a 20 ft. cone, huge fans begin to spin and blow a strong gust of air, pushing any targets prone and straight out of the area, possibly into other hazards. At level 1 the fans can push about 250 lbs, going up to 3000 lbs at level 20. Objects can be wedged into the fans to jam them, or shredded based on their durability. 3 (1d10)

Trigger: magic detection, activates when magic is detected in an area.

Countermeasures: A spell or other effect that can sense the presence of magic, such as detect magic, reveals an aura of divination magic around the area. A successful dispel magic (DC 10) cast on the area destroys the trap.

Acid Splash 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: +4 to hit (or DC 10) against one target, Casts Acid Splash 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.

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.
