Pits of Inferno Spa

PoI Spa (sometimes called DT City) is a large room that is found after passing Hall of the Four Ways and Pits of Inferno Levers. It contains creatures such as Diabolic Imps, Nightmares, Defilers, Destroyers, Hellfire Fighters, Phantasms, Dark Torturers, Plaguesmiths, Blightwalkers and Fire Devils.
The creatures here, especially Dark Torturers, drop really great loot, which makes this a good place to gain some profit.
