Add a Prayer for PC's Trapped in Mystic's Room
Similar in spirit to the prayer for pickaxes in the elemental temples, there could be an expensive prayer for players trapped in the dwarven mystic's room. If the PC doesn't have a means of teleportation, the prayer would grant a 0 charge wand of teleportation (chaotic gods maybe would grant a 0 charge wand of destruction). Obviously, this is a pretty rare situation, but I think it would be a fun little detail.
