Investiture of Flame Trap

This trap is activated when a creature touches its surface, which releases the spell stored within the trapped object. The object is covered in arcane symbols and writing.

Effect: +7 to hit against one target, Casts Investiture of Flame centered on the trigger with DC 14 (if relevant)

Trigger: touch trigger, activates when surface is touched by a creature.

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 surface. A successful dispel magic (DC 14) cast on the surface destroys the trap.

Casting dispel magic (DC 10) on the trap will cancel the stored spell.

Flamethrower Turret

This trap is activated when an intruder steps on a hidden pressure plate that activates pipes in the walls that spew flames. The area is unusually warm and has exposed pipes or perforated walls.

Effect: Targets all creatures within a 20 ft. cone, DC 14 DEX save or take 55 (10d10) fire damage

Trigger: pressure plate, activates when 20 or more pounds are placed on it.

Countermeasures: A successful DC 10 Wisdom (Perception) check will spot the pressure plate, and wedging an iron spike or other object under the pressure plate prevents the trap from activating.

Destroying the trap will rupture the pipes and spray flames over the area. Water can't adequately douse the flames, but clay or stone (such as with Stone Shape) can be used to block the geysers.

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.
