Sara’s Abilities (Phase One)

Sara is not attackable in Phase One and casts these spells randomly on the raid and on the Guardians of Yogg-Saron.

• Sara’s Blessing – Heals a friendly target for 27000 to 33000, but causes 60000 Shadow damage over 20 sec.
• Sara’s Anger – Inflicts 12500 Shadow damage every 3 sec, but increases Physical damage done by 12000. Lasts 12 sec.

Keepers’ powers

Talking to the Keepers of Ulduar before the fight will cause them to aid you in the encounter. The less you have helping the harder the encounter will be but better loot will drop and special achievements can be earned. Specific Keeper abilities below:

• Speed of Invention – Increases all damage done by 10% and movement speed by 20%.
• Mimiron also slows the casting speed and attack speed of all mobs in the encounter by 300%/100% respectively.
• Resilience of Nature – Increases all damage done by 10% and healing received from all sources by 20%.
• Freya also conjures Sanity wells allowing you to regain sanity.
• Fury of the Storm – Increases all damage done by 10% and total health by 20%.
• Thorim also finishes off Faceless Ones you bring to 1% HP in Phase Three. Without Thorim the Faceless ones are unkillable.
• Fortitude of Frost – Increases damage done by 10% and reduces damage taken from all sources by 20%.
• Hodir’s Protective Gaze – Allows Hodir to save a friendly target who sustains fatal damage by encasing them in a nearly impenetrable block of ice for 10 seconds. Hodir must rest after performing this action.

Yogg-Saron’s Abilities:

• Dominate Mind – Dominates the mind of the target, temporarily placing them under Yogg-Saron’s control. Also reduces Sanity by 4%.
• Sanity Well – Standing in the well brings you back to your senses, regenerating 20% Sanity every 2 sec. Damage done is reduced by 50% while you remain in the well.
• Psychosis – Inflicts 7500 Shadow damage. Also reduces Sanity by 9%.
• Brain Link – Links the brains of two enemy targets. Afflicted targets suffer 3000 Shadow damage and lose 2% Sanity every 1 sec. whenever they are more than 20 yards apart.
• Malady of the Mind – Inflicts 5000 Shadow damage and causes the enemy target to run in horror for 4 sec, then attempts to jump to another enemy within 10 yds. Also reduces Sanity by 3%.
• Lunatic Gaze – Looking into the maw of madness unhinges your mind, inflicting 5700 to 6300 Shadow damage and reducing Sanity by 4% every 1 sec. for as long as you are facing the caster.
• Induce Madness – Drives all nearby targets insane, reducing Sanity by 100%

Phase One: Have tanks pick Guardians of Yogg-Saron and kite them around the room and make sure you tank then away from the clouds that spawn. Anyone touching the clouds on the ground will spawn a new Guardian of Yogg-Saron, meaning you will eventually get overrun.

Abilities of “Guardians of Yogg-Saron”

• Mind Control: Cast on random players in the raid. Players must be CC’d or else they will destroy your casters/healers.

The Key to this phase is HOW you kill the Guardians. Each Guardian must be killed right next to Sara. After Killing 9 Guardians next to Sara the phase will end Phase 1 bringing you into Phase 2.

• It can be helpful to spawn an extra Guardian intentionally early on to start phase 2 faster as the Guardian spawn rate picks up the longer you remain in phase one.

Phase Two: Make sure you go into this phase with little or no Gaurdians up because you will immediately be overrun by tentacles. If you are using Freya and your sanity gets low, the green beams on the sides of the room will restore your sanity. Make sure to make use of it.

Types of Tentacles:

1.      Crusher Tentacle: Melees hard, has a ton of HP and has an aura that reduces damage done by the raid by 20%, stacks with other crusher tentacles so these must go down fast. Melee-ing these will interrupt their aura but they gain a temporary buff that increases their damage and attack speed when they are hit so this is dangerous if they are being DPS’d.

2.      Corruptor Tentacle: Casts various debuffs, Curse of Doom, Apathy, Draining Poison and Plague. Dispellers will need to be on their A-Game. All of these abilities are interruptible.

3.      Constrictor Tentacle: These have very little HP and appear underneath random players, grab them and hoist them into the air doing damage every few seconds until killed. Healers must heal the player being constricted

Note: Sara will hover above Yogg-Saron’s main body casting various abilities such as Psychosis, Brain Link and Malady of the Mind as well as lasers on the ground much like Kologarn’s eye beam.

Every 90 seconds or so Portals will open into Yogg-Saron’s mind. All melee DPS must take the portals. Do not take the portal if your sanity is low you will lose sanity the longer you are below.

You will see one of three random illusion rooms along with some disguised tentacles and laughing skulls floating around the room.

• The skulls cast Lunatic Gaze so you must strafe around the room with your back to the skulls at all times.
  • The illusion will shatter once you kill all the tentacles in the room.

Melee must then run into the brain room and try to get some DPS on the brain before taking the portal back up. The Brain begins a 60 second induce madness cast when the portals open so the melee must complete their task and get whatever DPS they can on the brain within 60 seconds or they will emerge from Yogg-Saron’s mind insane.

• This Means… You have about 50 Seconds of DPS before you must take the portal, to be safe, or you loose your DPS.

Phase 2 ends when the Brain is killed.

Phase Three: This is burn phase with a 5 minute enrage timer.

• Yogg-Saron will have 16 million HP left on 25-man and 3 million HP on 10-man.

Adds:

• Tentacles: These will stop spawning, any up will remain. Make sure you kill them.
• Faceless Ones: These adds hit very hard will spawn very rapidly in this phase. You must pick up and kill the Faceless ones, while also keeping enough DPS on Yogg-Saron to kill him within 5 minutes.
• Alternate to this: Burn Yogg-Saron extremely fast if you are not using Thorim.

Sara’s abilities continue. Yogg-Saron will begin to cast Lunatic Gaze in this phase so DPS must be ready to avert their eyes. Yogg-Saron will also heal the faceless ones with empowering shadows. It is recommended to save Bloodlust for this phase if you are horde.

• Lunatic Gaze - Looking into the maw of madness unhinges your mind, inflicting 5700 to 6300 Shadow damage and reducing Sanity by 4% every 1 sec. for as long as you are facing the caster.

General Vezax Boss Strategy Guide

Looking for more amazing Ulduar strategies? Check out the complete Ulduar Boss Strategies Guide!

General Vezax is the 12th boss encounter of Ulduar. General Vezax guards the prison holding Yogg-Saron.

General Vezax Abilities

• Health Points: 25,100,000 (heroic), 6,275,250 (normal)
• Shadow Crash – deals 11,310-12,690 shadow damage and knocking back all enemies near the impact point. Leaves a magical area at the impact point for 15 seconds that increases magic damage by 50%, reduces healing by 50%, and reduces mana cost by 30%.
• Searing Flames - deals 13,875-16,125 fire damage to all players within a 20 yard radius. Reduces armor by 75% for 10 seconds. 2 second casting time, can be interrupted.
• Surge of Darkness – increases physical damage by 100% and reduces movement speed by 55% for a 10 second duration. When the General buffs himself with this you  must kite him.
• Aura of Despair - prevents normal mana regeneration through out the fight. You can still gain mana via evocation, mana pots, etc. You can destroy the crystals flying around the room to get mana. These crystals drop a cloud on the ground, which will convert your health into mana.
• Profund of Darkness – deals 500 damage to all enemies and increases shadow damage by 10% per stack. Stacks on the raid (related to achievements)

General Vezax Boss Strategy

For the most part this is a pretty standard tank and spank fight…with a few slight variations. When you engage General Vezax simply start DPS like normal, have your DPS interrupt searing flames as often as possible. When General Vezax casts surge of darkness all DPS should stop, allowing your tank to kite General Vezax around the room. This is a great time for your casters to take advantage of the clouds for mana regeneration. Make sure you are rotating your casters appropriately, it’s important everyone maintains thier mana (particuarlly healers).

Continue to DPS General Vezax until he is about 35% health. Before reaching 35% you’ll want to make sure all your casters have enough mana, if not slow DPS and allow them to get some mana regeneration going. After you take Vezax to 35% he will summon Saronite Animus. Generally you want to simply off tank Saronite Animus and finish off the general. If you want to complete the achievement you need to kill Saronite Animus before Vezax. Continue burning down the General until he’s dead.

General Vezax Hard Mode Strategy

The hard mode is the same type of fight as I’ve detailed above, except you cannot use any of the mana-regeneration clouds for the duration of the fight.’

Hodir Boss Strategy Guide

Looking for more amazing Ulduar strategies? Check out the complete Ulduar Boss Strategy Guide!

Hodir is the 11th boss encounter of Ulduar. He’s located in the Halls of Winter.

Hodir Boss Abilities

• Health Points: 25,000,000 (heroic), 8,400,000 (normal)
• Melee hits on plate for up to 25,000
• Biting Cold – Aura that stacks up, dealing frost damage. Move to dispel the DoT.
• Freeze - Deals 5,550-6,450 frost damage, immobilizing them for 10 seconds. 10 yard radius, dispellable.
• Flash  Freeze – Freezes players in ice blocks, kill these ice blocks immediately. If a player is hit by a 2nd flash freeze they will die.
• Icicles - shards fall from the sky dealing a knockback and 12,000 frost damage to all players within the radius. These also create snowdrifts, which you can stand in to avoid being hit by flash freeze.
• Frozen Blows – self buff, adds 40,000 frost damage to all melee attacks and reduces physical damage by 70%.

Hodir Boss Strategy

Throughout the entire encounter you’ll need to constantly be moving to avoid biting cold. Periodically Hodir will randomly root a member of the raid, all players within a 10 yard radius will also be rooted. Stay spread out as much as possible to avoid large groups being rooted. Priests and paladins will need to be quick on their dispels here to avoid losing anyone.

Be watching for snowflakes pouring down from the ceiling, these indicate that icicles are about to fall. Anyone hit by these will take 12,000 frost damage and get knocked back.

Periodically Hodir will use frozen blows on himself. This essentially turns his damage from physical to frost. When this happens your frost resist tank needs to taunt. Healers should also be prepared to transition to the new tank. When frozen blows falls off the primary tank should taunt him back.

Finally, you’ll want to watch out for flash freeze. These are preceded by two icicles that create a snow mound. These mound of snow will protect the entire raid from being hit by the icicle. Anyone that doesn’t make it to the mound of snow should have their iceblock killed immediately to avoid death.

Hodir Hard Mode Boss Strategy

Defeat Hodir before he can shatter any of the chests in the room. The first chest is shattered at the 3 minute mark

Thorim Boss Strategy

Before the fight even begins you’ll want to split your raid into 2 groups. Group 1 will be the gauntlet group and should be composed of at least 2 tanks, 3 healers and caster DPS. Group 2 will be the Colosseum group and will fight the mobs in the arena area. This group should also have 2 tanks, 3 healers and your melee / hunter dps (due to the silence). The gauntlet group will work their way up to Thorim and the Colosseum group will simply fight the mobs and survive until group 1 makes it to Thorim.

After group 1 completes the gauntlet Thorim will jump down into the Colosseum, group 1 will follow him. At this point it’s a pretty standard tank and spank fight. When Thorim hits a tank with unbalancing strike another tank will need to taunt. Continue pumping out as much DPS as possible. Now it’s just a DPS race against lightning charge, which will 1 shot tanks.

Thorim Hard Mode Strategy

Most are saying the hard mode encounter includes Sif, Thorim’s dead wife. She won’t be tankable and will simply run around producing additional raid damage. Note that this has yet to be confirmed.

Auriaya Boss Strategy

When you pull Auriaya you’ll need 1 tank holding Auriaya and 1 tank managing the adds. The raid should be pilled up with the adds and killing them as quickly as possible. Your main tank who has Auriaya will want to be around 20 yards away with the boss facing the raid. This is due to the sonic screech ability.

After the raid has killed the adds they can begin attacking the boss, ensuring that they are always standing in front of the boss (melee specifically). When the feral spirit spawns you off tank needs to pick him up. After you’ve killed the feral spirit he will drop a seeping feral essence, similar to a void zone…so don’t stand in it.

After you’ve killed the add you can begin attacking the boss again. Shortly the feral sprit will be resurrected and you’ll need to repeat the above steps. Continue dragging the boss around to provide drop areas for the seeping feral essence until you’ve killed the boss.

  • Lightning Tendrils – Stormcaller gains this buff after two of the other bosses have been killed first. Runs around the room very fast and deals 8,000 damage per second to anyone nearby. Should be taunted back to the floor, where you can DPS him.

The Iron Council Boss Strategy

Phase 1 – All 3 Bosses Up

Raid groups can kill the 3 bosses in any order you wish, however, the generally accepted easiest route is Steelbreaker –> Molegeim –> Brundir. Step one in this fight is simply setting up your tanking positions. Steelbreaker and Molgeim should be tanked in the front corners of the room. Due to the overload explosion you must tank Brundir away from the raid, generally towards the back of the room is the optimal position.

Boss Specific Notes

• The tank on Brundir needs to run away from the boss as Overload is going off, minimizing damage.
• Players attacking Brundir should always try to interrupt chain lightning casts.
• Molgeim will drop rune of power throughout the fight underneath Brundir and Steelbreaker. Tanks should reposition these bosses when this occurs to remove them from getting the buff and allow your DPS to get the buff.
• Steelbreaker will be fusion punching your tank. When this occurs he will need additional heals and a dispel.

Phase 2 – 2 Bosses Up

After your raid has killed the first boss the other two bosses will gain new abilities. If you are killing the bosses in the order suggested above then you’ll have Molgeim and Brundir up at this point.

Boss Specific Notes

• Molegeim now has Rune of Death. Massive green AoE rune on the ground, deals 6,000 damage per second to those players standing within it. Move out of it.
• Brundir now has lightning whirl. Randomly tosses lightning bolts at raid members, heal through it.

Phase 3 – 1 Boss Up

At this point only Brundir is left up, so let’s take him down! With Molegeim now dead Brundir gains a new ability, lightning tendrils. Using these tendrils he will lift up into the air. Anyone standing nearby will take massive amounts of nature damage…so, don’t stand near the boss if you’re not a tank.

You can keep Brundir in the same location by rotating taunts with 3 tanks. Thus allowing your range DPS to deal more damage. In addition, Brundir will occasionally drop to the ground, allowing melee DPS a chance to get some DPS in.

At this point it’s simply a matter of continuing to burn Brundir down and keeping heals flowing. Keep it up and you’ll have Brundir down in no time.

The Iron Council Hard Mode Strategy

To complete The Iron Council on hard mode you must kill Steelbreaker last.

Complete strategy for hard mode will be added in the coming days.

XT-002 Deconstructor Boss Strategy Guide

Looking for more amazing Ulduar strategies? Check ou the complete Ulduar Boss Strategy Guide!

XT-002 Deconstructor is the 4th boss of Ulduar. He’s located in the Ulduar scrap yard.

XT-002 Deconstructor Boss Abilities

• Health Points: 17,850,000 (heroic), 5,250,000 (normal)
• Gravity Bomb – Targets a random playing causing them to explode and pull in nearby players after 9 seconds. Creates a gravity well.
• Gravity Well – Created by the gravity bomb on the targeted player, which pulls players within a 10 yard radius into the well, dealing 19,000-21,000 damage.
• Tympanic Tantrum – Deals 10% damage every 1 second for a 12 second duration to the entire raid, dazing all enemies. Cast once per minute.
• Light Bomb – Causes targeted player to deal 2,000-3,000 damage to nearby players while they are attacking, last for 9 seconds.
• Enrages after 8 minutes

XT-002 Deconstructor Boss Strategy

This encounter is a standard tank and spank fight for the most part. The most important aspect of this fight is simply spreading out. After a player gets hit with a gravity bomb or a light bomb that player needs to immediately separate themselves from the group to minimize damage. Furthermore, healers should be on the lookout for tympanic tantrum. This will deal 120% damage to all raid members over 12 seconds, so every raid member will need to at least receive a decent amount of heals. It’s not a bad idea to assign healers to individual groups, as to ensure all players receive a heal.

At 75%, 50%, and 25% XT-002 Deconstructor will stop attacking and spawn adds. There are 3 different kinds of adds.

• XS-013 Scrapbots – these adds will heal XT-002 if they get to him, they must be killed immediately.
• XE-321 Boombots – these adds blow up, dealing damage to friend and foe alike, when they hit 50% health. These can be used to kill the other adds.
• XM-024 Pummelers – Basic mobs, nothing special, you can kill these after boombots and scrapbots have been killed.

After the adds have been killed the fight will continue like before.

XT-002 Deconstructor Hard Mode Strategy

During any of the ad phases XT-002 may be clicked on. Doing so will expose his heart, which may be destroyed. Destroying his heart will increase XT-002′s health and damage by 25% and return him to full health. Exposing and killing the heart at the lower add spawning levels does not increase the quality of loot or open up new achievements, this is a binary hard mode fight.

Razorscale Boss Strategy

Phase 1 – Air Phase

To start phase 1 simply talk to the expedition commander. During this phase you are tasked with defending the dwarven crews while they repair the harpoon launchers. Your primary focus here is killing all of the adds and avoiding the devouring flames that Razorscale will be launching.

As each harpoon launcher is successfully repaired they may be clicked to fire a harpoon at Razorscale. After all 4 turrets have been fired Razorscale will come to the ground. Once on the ground Razorscale will be stunned temporarily, during this time your DPS will want to blow all cooldowns to do as much damage as possible.

After the stun ends Razorscale will fly up into the air again and you’ll repeat the firing process to bring her down.

Phase 2 – Ground Phase

Once you’ve got Razorscale below 50% she will land. During this phase you’ll want your tank to spin her face away from the main raid to avoid flame breaths. At this point the fiight becomes a standard tank and spank fight. Continue to avoid devouring flame and keep DPS up. As flame buffet stacks on your tank he will be taking some serious damage towards the end of the fight, so maximizing your DPS during this phase will be crucial.

Flame Leviathan Boss Strategy

As soon as you engage Flame Leviathan he will randomly target a siege engine vehicle. The driver of this vehicle must kite the boss. Initially it’s very easy to kite, but as time passes Flame Leviathan will begin to pickup speed, making it more difficult.

Every 30 seconds Flame Leviathan will target a new siege engine, which will be tasked with kiting (if a siege engine is not alive he will target a demolisher or chopper). This fight really comes down to the kite and each vehicle fulfilling its role successfully (as described below).

Siege Engine Role

While this kiting is going on other players in siege engines can be doing damage with ram and more importantly using electroshock to interrupt flame jets. However, be prepared to kite as the 30 second kite cycle comes to an end. The passengers of the siege engines should be shooting down pyrite ammo in the air. If there aren’t any pyrite ammo left they may DPS the boss.

Demolisher Role

Demolishers are the bulk of the damage output on this fight. Your demos should be attacking the boss with hurl boulder, hurl pyrite barrel, and launch passenger. In order to maximize damage it’s a good idea to save your hurl pyrite barrel for when the overload circuit has been activated.

Interlude on Catapult Passenger Launch

After your overload circuit wears off you’ll want to have your demolishers launch a single DPS class and a single healer to the back of Flame Leviathan. There are 4 turrets here, after killing a target a button will pop up. You will channel a cast on this button and upon completion Flame Leviathan will be stunned, increase the damage you deal to him by 50%, and reset his movement speed. These players will be knocked off Flame Leviathan and should be promptly picked up by a chopper and returned to a demolisher, in preparation for the upcoming launch.

Choppers Role

Chopper’s are tasked with dropping their flammable oil slicks on the ground in front on Flame Leviathan. This will slow him and deal additional damage if they catch fire. In addition, choppers should be picking up any players that are coming off the back of Flame Leviathan or players that have been launched and missed their targets.
