At the north end of a long combustion diverting tube, this strangely diamond shaped chamber doesn’t have a door in the traditional sense, but instead has a narrow entrance that can be squeezed into but is very difficult to leave. DC STR 21. Every 3 rounds the chamber is filled with superheated metaline if the machinery in 3.9 is functioning. Inside the room a plasma elemental has become trapped (it is just a dill). While it is technically “fed” every time the combustion event occurs it will attack anyone that enters, believing them to be its jailor.
