Overwhelming Power must be tanked by a single Tank, while the other two are handled by the second Tank.

Make sure to always interrupt Chain Lightning.

Fusion Punch has a cast time, and it should be interrupted immediately, otherwise, it will likely kill the Tank.

Mages should always Spellsteal Shield of Runes or it should be dispelled if there is no mage in the group.

Ranged and healers should be spread out when Rune of Death is about to happen to avoid having too many people on top of it when it spawns. It has a big area of effect.

Tanks should move bosses Rune of Power, and DPS should try to stand on top of it to increase their damage.

When doing the Hard Mode, tank swap before Overwhelming Power expires, as it will kill any players in a radius around the tank.

Stormcaller Brundir is the easiest boss to kill last. His ultimate ability, to summon Lightning Elemental, is easily avoidable, and his first Supercharge mechanic, Lightning Whirl, is interruptible.

Lifebinder's Gift Summon - Summons an Eonar's Gift, which uses Lifebinding Heal after ~12 seconds, healing Freya and her allies for 30-60% of their maximum health. Eonar's Gift's Pheromones negates the effect of Conservator's Grip on nearby players.

Summon Allies of Nature - Summons one of the three following waves of adds every minute. A total of 6 waves will be summoned. Killing any of the adds reduces the number of stacks of Freya's Attuned to Nature.

Ancient Conservator - Reduces Freya's Attuned to Nature by 30 stacks. Applies Conservator's Grip when he spawns, preventing players from attacking or casting spells. Getting under one of the many Healthy Spores or an Eonar's Gift negates the effect. He will also debuff players with Nature's Fury, which causes the debuffed player to damage nearby allies for moderate Nature damage every 2 seconds for 10 seconds.

Nature Bomb - Summons immobile Nature Bombs around the feet of random raid members. The bombs use Nature Bomb after a few seconds, inflicting moderate Nature damage to enemies within 10 yards and knocking them back. Use frequently.

Summon Allies of Nature

Move away from Sunbeam.

Ranged DPS (and Melee if possible) prioritize killing Eonar's Gift. If Eonar's Gift lives for 12 seconds, it will heal all Allies of Nature and Freya.

Allies of Nature

Detonating Lasher

Death Knight's Gorefiend's Grasp is extremely helpful with these Allies, as you can pile them together easily and AoE them down.

Melee be aware, they cleave with Flame Lash while alive and Detonate upon death.

Elemental Adds

All three adds, Ancient Water Spirit, Storm Lasher, and Snaplasher must die within 12 seconds of each other, or they will revive.

Be mindful that Ancient Water Spirit will run away with Tidal Wave, reducing damage taken by being too far and

Ancient Conservator

Due to Conservator's Grip, Ancient Conservator should be tanked underneath a Healthy Spore to prevent that effect. Ranged and Healers should find other Healthy Spore, not necessarily in melee range.

Players might need to leave their Healthy Spore if they are affected by Nature's Fury near allies.

Emergency Mode

Fiery Explosions - Mimiron will randomly select 3 players, who will explode soon. A fire will spawn from each explosion (for a total of 3 fires). The fires will slowly chase raid members and may switch targets on the way. Used during all phases.

Flame Suppression (Phase 1) - 60 seconds after engaging, Mimiron will flood his chambers and douse all currently spawned fires.

Frost Bomb (Phase 2, Phase 4) - Spawns a Frost Bomb in one of the triptychs of the room. The Frost Bomb will grow for several seconds and then explode, dousing all flames in that triptych and knocking players back.

The Descent into MadnessGeneral Vezax

Aura of Despair - Prevents most mana regeneration methods. Melee attack speed is reduced by 20% for all raid members as well.

Shadow Crash - Shoots a shadow missile towards a random target (preferring Ranged), inflicting 11,310 to 12,690 Shadow damage to the target and anyone in a 10-yard radius. A dark puddle spawns under the area of impact, increasing magical damage by 100%, decreasing casting speed by 100%, and healing done and mana cost by 75%.

Mark of the Faceless - Applies a Mark of the Faceless to a random raid member (preferring ranged), causing them to drain a moderate amount of hit points every 1 second, for 10 seconds, from other nearby players. Vezax will heal for 20 times more health than he has drained.

Searing Flames - Inflicts high Fire damage to everybody in the room, and reduces their armor by 75%. Can be interrupted.

Surge of Darkness - Increases Vezax's damage by 100%, but decreases his movement speed by 55%, for 10 seconds. Cast every 60-70 seconds.

Saronite Vapors - Throughout the encounter Saronite Vapors will appear at random locations. Killing them drops a green pool that restores mana to all standing on it, but also deals scaling shadow damage the longer the player stands on it.

Saronite Barrier - Reduces all damage taken by 99%. Cast if 6 Saronite Vapors spawn and not a single one of them is destroyed. Vezax will also summon a Saronite Animus. The Barrier disappears when the Animus dies.

Saronite Animus - Casts Profound Darkness frequently, which does 750 Shadow damage to the entire raid and increases the Shadow damage taken by 10%.

The most important factor in this fight is the lack of Mana to all Healers, due to Aura of Despair. Healing done should be efficient, and damage taken avoided.

Avoid Shadow Crash. It creates a shadow in the location it will drop.

Players targeted by Mark of the Faceless should move out of the group to avoid healing the boss.

The group should have a 3-stage interrupt rotation for Searing Flames, with two people assigned for every interrupt, should the other fail. Letting one cast off costs a lot of Mana on your healers. Warning: it is a fast cast.

Tanks should use strong defensive cooldowns for Surge of Darkness.

Saronite Vapors should be killed efficiently to replenish healers' Mana.

Saronite Barrier - Reduces all damage taken by 99%. Cast if 6 Saronite Vapors spawn and not a single one of them is destroyed. Vezax will also summon a Saronite Animus. The Barrier disappears when the Animus dies.

Saronite Animus - Casts Profound Darkness frequently, which does 750 Shadow damage to the entire raid and increases the Shadow damage taken by 10%.

I Love the Smell of Saronite in the Morning Glory Achievement - Defeat General Vezax in Ulduar after defeating the Saronite Animus.

Shadowdodger - Defeat General Vezax in Ulduar without any raid member being hit by Shadow Crash.

Yogg-SaronUlduar

The Keepers of Ulduar

Hodir - Buffs the raid with Fortitude of Frost, which increases damage done by 10% and reduces damage taken by 20%. He can also use Hodir's Protective Gaze to save a player from what would otherwise be a killing blow. This spell has a 25-second cooldown.
Mimiron - Buffs the raid with Speed of Invention, which increases damage done by 10% and movement speed by 20%. He can also use Destabilization Matrix to reduce the attack speed by 100% and casting speed by 300% of all Crusher and Corruptor Tentacles during Phase 2.

Psychosis - Inflicts moderate Shadow damage and reduces Sanity by 12%. Cast on a random raid member.
Malady of the Mind - Inflicts low Shadow damage, causes a fear effect for 4 seconds, and attempts to jump on another player within 10 yards after the effect is over. Also reduces Sanity by 3%.
Brain Link - Connects two random targets with a beam, causing them to suffer low Shadow damage and 2% Sanity loss every 1 second they are more than 20 yards away from each other. Lasts 30 seconds, or until one of the players dies or enters a portal.
Death Ray - Summons 4 Death Orbs, each inflicting high damage per second to players standing in them.
Descend Into Madness - Approximately every 90 seconds, 4-10 portals will open to Brain of Yogg-Saron. Players taking them may be hit by Lunatic Gaze if they face the laughing skulls around the room.
The Brain Chamber - Players inside the illusions will need to quickly kill the fake NPCs (e.g., Suit of Armor) inside, which will open a passage to the brain room. Attacking the brain will cause Shattered Illusion, which stuns all tentacles outside the brain room. As soon as the portals open, Induce Madness is cast—players need to leave the brain room through portals in it before the cast is over.

Phase 2: Tentacles

Cast Apathy, which reduces attack, casting and movement speed by 60% for 20 seconds (Magic effect); Black Plague, which stuns the target for 2 seconds every 3 seconds (Disease); Curse of Doom, which inflicts 20,000 Shadow damage after 12 seconds (Curse); Draining Poison, which inflicts 3,500 Nature damage and drains 1,400 mana every 3 seconds for 18 seconds.

Phase 3: An Old God

Shadow Beacon - Targets an Immortal Guardian for Empowering Shadows.
Empowering Shadows - Regenerates Hit points every 1 second, for 20 seconds to nearby allies. Cast on the Shadow Beacon 10 seconds after the buff is applied.

Deafening Roar - Inflicts moderate Physical damage and silences the raid for 4 seconds. Only cast with at least one Keeper not active.

Phase 1 - Sara the Ally

There are two main strategies for groups on Phase 1: You either will stay at the entrance of the room, far from all Gas Clouds, or the group will walk around the Gas Clouds grouped up together. The second method requires your whole group to be coordinated so as not to trigger extra Guardian of Yogg-Saron.

The Main Tank should grab all Guardian of Yogg-Saron available at the moment, while the Off-Tank taunts them off when they get low on health and moves them near Sara, to damage her. Phase 2 starts as she reaches 1 HP.

There should be Ranged DPS assigned to help the Off-Tank kill low health Guardian of Yogg-Saron.

Phase 2 - Sara the Enemy

Phase 2 introduces the main mechanic of the fight: Sanity. It basically limits the number of mechanics you can be targeted by and can ignore, as all mechanics will decrease your Sanity by a small amount. If you reach 0 Sanity, you lose your will to Yogg-Saron.

If you have Freya helping you, make sure to run to Sanity Wells if your Sanity gets too low.

Ranged and Healers should try to stay spread out around the room so it is easier to avoid players with Malady of the Mind.

Brain Link targets should stick together for its duration, unless entering into a Brain Portal. Coordinate your movement while under its effect to minimize Sanity lost.

Don't run over Death Rays.

4-10 players should be assigned beforehand to enter the Brain Room. They should be assigned general directions around Yogg-Saron so they can enter their portals as fast as possible.

If you're assigned to go inside the Brain Room, save all your DPS cooldowns for its second part. Kill all illusions as fast as possible and avoid looking at Lunatic Gaze. You have 1 minute total from the moment the Brain Room opens to complete it; if you fail to leave, you will fall under Yogg-Saron's will.

Kill Constrictor Tentacle as fast as possible to minimize Sanity lost.

The second priority during Phase 2 are the Corruptor Tentacles, make sure to interrupt them as much as possible and remove as many negative effects as possible.

The last priority during Phase 2 are Crusher Tentacles, they need to be tanked and are usually killed during the Brain Paralysis that happens when the Brain is exposed.

Once the Brain is brought to 30% HP, Phase 3 starts.

Phase 3 - An Old God

Never face Yogg during Lunatic Gaze to avoid losing Sanity.

The raid should kill off any tentacles left from Phase 2 entering this phase.

Immortal Guardian will spawn periodically during this Phase. They should be picked up by Tanks and cleaved down by the raid. As their name suggests, they are immortal. Unless you have Thorim aiding you! He can kill them with Titanic Storm.

If Thorim is not aiding your group, you still should keep Immortal Guardian at low health points as it reduces their damage done due to Empowered.

Tanks should rotate defensive cooldowns every time Yogg-Saron casts Empowering Shadows on the Immortal Guardian, as they will be healed back to full HP and start hitting harder.

If at least 1 Keeper is missing, Yogg-Saron will cast Deafening Roar, interrupting all spell casting.

If you have Freya helping you, make sure to run to Sanity Wells if your Sanity gets too low.

Big Bang - Inflicts deadly Physical damage to anyone not standing inside a Black Hole. Removes players from Black Holes.

Ascend to the Heavens - Inflicts deadly damage to all enemies. Cast 6 minutes after engaging him. Equivalent to Berserk.

Collapsing Star - Summoned periodically during Phase 1. They lose 1% health each second and cast Black Hole Explosion as they die, which inflicts high Shadow damage to the entire raid. They leave Black Hole on the ground as they die.

Black Hole - Spawned by dying Collapsing Star. Players standing in a Black Hole are shifted to the Worm Hole dimension, taking low Arcane damage every 1 second spent shifted. Dark Matters populate the Worm Hole. If a Living Constellation enters a Black Hole, both despawn.

Living Constellation - Spawned in threes periodically during Phase 1. Attack with Arcane Barrage, which inflicts moderate Arcane damage. If a Living Constellation enters a Black Hole, both despawn.

Dark Matter - Spawned inside Worm Hole dimension during Phase 1. Attack any raid member who enters a Black Hole. Spawned periodically from Black Holes during Phase 2.

Phase 1 - 100% to 20%

Tanks can get destroyed in this fight; always have a dedicated Tank Healer and communicate Tank-swaps clearly.

During Phase 1, four Collapsing Star will periodically spawn. They lose life over time and will die at the same time if no damage is dealt to them. You must assign a couple of ranged DPS to kill them one by one, making sure no one is near them as they spawn a Black Hole upon death.

Never kill a Collapsing Star when Cosmic Smash is happening, as their damage combined is likely to kill someone.

Living Constellation will periodically spawn on Phase 1 and should be used to close unnecessary Black Holes. They destroy Black Holes when they enter them. Be mindful not to do that during Big Bang as it might close a Black Hole that was being used by someone.

Tanks will swap when the 5th stack of Phase Punch happens, as it will phase the other tank. Whenever that happens, the tank is sent to the Black Hole dimension for 10 seconds.

Every 1m30s Big Bang will happen. Everyone but one person should run inside Black Holes. One person must stay out and endure the damage from Big Bang. Good candidates for this are Tanks with strong external cooldowns, like Pain Suppression or any person with Guardian Spirit. Death Knights are good candidates, with Anti-Magic Shell and Icebound Fortitude.
Should Big Bang not hit someone, the Raid Destroyer will immediately cast Ascend to the Heavens, terminating the encounter.

Big BangAscend to the HeavensPhase 2 - 20% to 0%

Phase 2 retains all mechanics from Phase one besides Living Constellations and Collapsing Stars. All existing Collapsing Stars and Black Holes will disappear, and four Black Holes will spawn permanently at the four cardinal points of the room. Dark Matter adds, normally found inside Black Holes, will now come out and need to be tanked by whoever isn't tanking the Raid Destroyer.

"Mimiron engineered this clockwork giant, who dominates the scrapyard area in Ulduar. XT-002 considers himself to be his inventor's son, causing the machine to behave like a young boy.

Teron Gorefiend periodically marks a player with Shadow of Death, killing them instantly. The slain player then returns as a Vengeful Spirit, with the unique ability to hinder and destroy Shadowy Construct that will otherwise decimate other players."

WOW :O

Are there any rewards besides 930 gear and the 500 badge quest for doing this?

Comment by Ryawy

Mark of the Faceless doesn't scale properly right now. It siphons 5000 from players near the target, which is more or less a 1-shot at the moment. My group had all of our ranged spread out in a semicircle (Holy paladins included) and we didn't have a problem. At normal Nathria ilvl, Surge of Darkness didn't hurt our tank enough to need to kite.
