This fight requires good EQ, because of the phase 3.
P1: Sara cannot be attacked directly. The only way to damage her is the AoE damage from dying Guardians of Yogg-Saron. In order to end the phase, you have to kill 8 Guardians close to Sara. You can speed up the appearance of adds by touching green-yellow clouds. Some dmg can be avoided by using Twilight Ward.
P2: In this phase, you will need a bit of luck. Quickly kill any remaining Guardians from phase 1. Your Sanity will drop to about 30. Before the appearance of portals to the Mind's Eye, you'll have to deal with two waves of tentacles. The first wave will consist of Constrictor Tentacle (/tar macro is useful here), Corruptor Tentacle and Crusher Tentacle. The second wave will consist of Constrictor Tentacle and Corruptor Tentacle. Corruptor Tentacle is a priority. If it manages to cast Black Plague (24sec debuff, which periodically stuns for 2sec), you probably wipe it. Before the appearance of portals, all tentacles must be destroyed. Remember to avoid the green beams. After using the portal, your task will be to put Corruption on every neutral NPC while not facing Laughing Skull. Your minion has to be close to you, when going through the portal, otherwise it will not pass through it. Then you have to destroy Brain of Yogg-Saron, before it finishes Induce Madness cast. In addition, you need 1000 Demonic Fury for phase 3, so you have to be very fast in this realm.
P3: Nuke phase. Go to the back of the Boss and let your minion to tank adds. When Lunatic Gaze is casts, you have to turn away from the Boss. Watch out for Sanity, because if it drops to 0, you will become insane. Pop up all offensive cooldowns and pray that you do not become a victim of Black Plague. Yogg-Saron must die before Immortal Guardians will start to heal. Good Luck and Have Fun!
