25-player · Coilfang Reservoir, Zangarmarsh · 6 bosses
The 25-player water raid of Phase 2, home to six bosses culminating in Lady Vashj. A serious step up in coordination — poison management, add control, and the infamous tainted-core relay on Vashj.
25-player · Netherstorm · 4 bosses
The blood elf fortress raid, four bosses ending with Kael'thas Sunstrider — a five-phase gauntlet against his advisors, their weapons, and Kael himself. The definitive Phase 2 progression check.
