Onyxia's Lair is a level 80 raid dungeon located in the Wyrmbog, Dustwallow Marsh. It is home to Onyxia, the brood mother of the black dragonflight. Onyxia's Lair was originally a level 60, 40-player raid dungeon, only one of two that were available upon release of World of Warcraft (the other being Molten Core). It was re-tuned as a level 80 raid dungeon in patch 3.2.2 in honor of World of Warcraft's 5-year anniversary. Like all other Wrath of the Lich King raid dungeons, it has both 10-man and 25-man modes.
