Firefight Trap CR 8
Type magical; Perception DC 32; Disable Device DC 32
Trigger touch (door); Reset automatic after 1 hour
Effect Two wall of fire spells (CL 7th) divide the room and summons three Large fire elementals that last for 13 rounds, as per summon monster VII (CL 13th).
If anyone touches the trigger (door) without saying the proper password, the doors instantly close and lock. To reopen them, three switches must be flipped simultaneously—locking mechanisms keep them from flipping individually. Doing so unlocks the doors, but also springs the second half of the trap. Immediately upon the throwing of switches, two walls of fire divide the room and three fire elementals appear, one near each switch, and attack the nearest creatures. As soon as the fire elementals are destroyed or disappear, the walls of fire end and the trap becomes dormant for 1 hour.
