WoW Ulduar Raid Guide - Yogg-Saron

 Yogg-Saron, the Old God imprisoned within Ulduar for millennia, has broken free of his prison and corrupted his wardens. Now the only thing that can stop him from ravaging Azeroth and visiting destruction upon all known life is you, and 24 other ragtag raiders. But you don't stand a chance without a guide. This Yogg-Saron boss strategy guide breaks down the encounter and explains how to defeat the madness monster on 10 and 25 man modes, with four Watchers assisting.

The difficulty level of the Yogg-Saron boss encounter is surprising at first. General Vezax is such a pushover you wouldn't think only one boss further into the instance would present such a challenge. But remember, this is an Old God we're talking about. It's supposed to be tough. Months after the Temple of Ahn'Qiraj was released (AQ 40) it was actually revealed that the Cthun Old God boss encounter couldn't be beaten, and it had to be scaled back. So put it in perspective - at least Yogg isn't impossible.

 Fortunately for you, your raid will not be facing off with Yogg-Saron all on its own. They will be receiving assistance from the four freed Watchers - Freya, Mimiron, Hodir, and Thorim. Each of these gives considerable buffs to the raid, as well as abilities that make the fight more manageable. It is possible to kill Yogg-Saron without the assistance of these Watchers, and there are achievements for doing it with only 3, 2, 1, or none of them. One Light in the Darkness is considered to be "hard mode" with improved loot, and Alone in the Darkness only offers up one additional reward - A vanity flying mount that looks like Mimiron's Aerial Command Unit.

Mimiron - Increases all damage done by the raid group by 10%, and movement speed by 20%. During phase two he also shoots a beam at tentacles that reduces their attack speed by 100% and their casting speed by 300%.

Freya - Increases damage done by 10% and healing received by 20%. Also creates Sanity Wells, which are green beams of light that restore Sanity when players stand in them.

Thorim - Increases all damage done by 10% and total HP by 20%. Also uses an ability during phase three which kills Immortal guardians with 1% health.

Hodir - Increases all damage done by 10% and reduces damage taken by 20%. Will also use Hodir's Protective Gaze which will sometimes save a player from death by encasing them in a block of ice.
