The Dire Sanctum (West Wing — Corrupted Library)
Dungeon, levels 39–49, 3 heroes, 4 bosses: abilities, loot and drop chances of every boss.
In the heart of the dead elven city chills a marble library-treasury, bound by fel magic. Floating books rustle on their own in the cold blue light, ghostly elven figures glide between the shelves, and demonic golems guard the ward-runes. The knowledge for which an entire city once died is still here—and the demonic altar in the far hall is still hot. Read quickly, strike first.
