This is my Story
Yogg-Saron is the final boss encounter of the Ulduar raid dungeon. It is mainly a DPS race, but also requires high situational awareness. Yogg-Saron with no keepers was the hardest boss to defeat in the game before Algalon. The fight is lighter on healing than Mimiron, one healer per five raid members is enough. Extra DPS reduces raid damage taken. Entering Yogg-Saron's room immediately starts the encounter. The fight has three phases, engaging Sara and her guardians first, then defeating the Brain of Yogg-Saron and finally his body. 15 minutes after the first raid member enters Sara's room, Yogg-Saron casts Extinguish All Life, which one-shots the raid.
