Tunnels & Trolls : Gristlegrim Room 413--Fire Opal room
This is a standard Gristlegrim room. It has secret doors on all four walls, requiring a level 4 saving roll on either Intelligence of Luck to find and open one.
Delvers could be trapped in this room. If that happens, have Gristlegrim appear and let them buy their way out for everything they own, setting them down in their loin cloths at the Dwarven temple down below.
The room appears empty except for the body of a young elven woman. Her body appears to be badly burned. If the body is searched, delvers will find a gold ring with a fabulously large fire opal set into it. The gem is hypnotically beautiful and worth 4000g.p. It is also cursed. Whoever puts the ring on cannot take it off again. The only way to get it off is to cut off the finger. The wearer of the ring draws all fire attacks to him/herself. The wearer also increases his/her CHR by 10 points.
