Flame pit

A Flame pit is an Oubliette trap. It takes 77 Construction to build. A Flame pit hits constant 100-300s while any players are in the trap.

Note: A crystal saw does work when making this, and so the minimum Construction level needed to build a flame pit is 67 construction (evil stew + crystal saw + sculpting chisel) providing you already have an oubliette although the plus six from the stew is so rare it is not worth trying to achieve. You can also use the combination of the crystal saw (+3 lvls) and tea(+1 or +2 depending on your kitchen shelf). Flame pits are popular as a way of killing players in a house, letting them recharge Prayer, Summoning, Special attack and life points, while curing poison at the same time. Also removing skull when pking.
