A flame pit is an Oubliette trap. It takes 77 Construction to build. A Flame pit hits constant 1-3s while any players are in the trap; a lever must be built in the throne room above for the flame pit to deal damage.

It can be built at 69 Construction, provided that the player gets a +5 boost from a spicy stew and uses a crystal saw for the remaining three levels. It is popular for killing players in the prison, as it deals consistent damage compared to the tentacle pool and the rocnar.
