The Secrets of Ulduar (25 player)
Defeat every boss in Ulduar in 25-player mode.
The Secrets of Ulduar (25 player) requires defeating every boss in Ulduar on 25-player mode, and notably does not require the hard-mode-only boss Algalon the Observer.
Enter Ulduar and clear all bosses
Enter Ulduar and defeat every boss in the raid. Algalon the Observer is not required for this achievement, so you can skip him entirely.
Defeat Yogg-Saron last
Yogg-Saron is the final boss required for this achievement, as the achievement was first completed worldwide upon a Yogg-Saron kill.
