How this dungeon is generated
3 floors on a 62x62 footprint, about 9 rooms each (sunken rectangular rooms, halls and poison-pool hazard rooms); about 75 mobs placed once, in packs of 2-4 with 1 mini-boss key carrier(s) and 2 elite pack(s) per floor, boss on the last floor; est. full clear 16 min. Layout, mobs and chests are seeded per visit, so every run is new and nothing respawns.
