Ignición will target a random player; after several seconds, that player will detonate, dealing moderate damage to players within 5 yards.

The Slag Behemoth throws a Bomba volcánica at a random player, which knocks back and damages all players near the point of impact.

The Bomba volcánica also creates a spike at the impact location, which blocks line of sight.

The Slag Behemoth will emit a Ola explosiva, dealing heavy raid-wide damage. Players can avoid this damage by line-of-sighting the boss behind a spike created by the Bomba volcánica.

Phase 1: Destroy the Regulador de calors on either side of the Blast Furnace

Phase 2: Defeat the four Elementalista primigenias who have captured the Heart of the Mountain

Phase 3: Defeat the Heart of the Mountain

Guardia de seguridadIngeniero del hornobefore initiating the fight, players should assign 1 tank, half the DPS, and half the healers to each side of the room

Each tank will take one Security Guard and one Furnace Engineer with them to their half of the room, and one of the tanks will need to pick up Foreman Feldspar.

If there are an uneven number of healers, have the extra healer follow Foreman Feldspar and heal the tank who is tanking him. While the raid is getting into position, and before any higher-priority targets spawn, players can spend some time damaging Foreman Feldspar.

Reventar

This deals unavoidable raid-wide damage and healers must be prepared to heal through it while still managing the healing tasks created by the other mechanics of each phase.

The rate at which the Heart of the Mountain gains Energy is influenced by his Heat level, which appears as an Alternate Power bar on the Heart of the Mountain's unit frame; the amount of Heat the Heart of the Mountain gains is determined by how well the players handle the mechanics of the first phase.

0-24 Heat: Reventar occurs every 30 seconds

25-49 Heat: Reventar occurs every 20 seconds

50-74 Heat: Reventar occurs every 15 seconds

75-99 Heat: Reventar occurs every 12 seconds

100 Heat: Reventar occurs every 10 seconds

Return to Table of ContentsPhase 1: SabotageBombaBomba

Furnace Engineers will target random non-tank players and cast Bomba on them.

Upon dying, Furnace Engineers Tirar bombas encendidas, creating a Grupo de bombas encendidas that contains three armed Bombas. Players can loot the bag to obtain a Bomba.

Security Guard - Frequently drops a shield on the ground, creating a zone of Defensa in which enemy creatures take 99% less damage

Bellows Operator - Increases the Heart of the Mountain's Heat levels; once Regulators die, Operators must be tanked, and will use Rugido ensordecedor

As long as Regulators are alive, Bellows Operators are not affected by the Security Guards' Defensa

Foreman Feldspar (mini-boss) - Creates Ruptura zones under random players' feet; targets random players with Piroestallido; deals moderate damage to nearby players with Sangre caliente

Foreman Feldspar > Bellows Operator > Furnace Engineer > Security GuardReturn to Table of ContentsTank Responsibilities

Pick up one Security Guard and one Furnace Engineer at the start of the fight and drag them to your assigned location

One tank should take Foreman Feldspar as well, and tank him until Ruptura zones are too cumbersome in that side of the room

If Ruptura becomes too invasive, tanks can meet in the middle of the room to pass Feldspar off

Move enemies out of Defensa zones

If Heat Regulators die while Bellows Operators are still alive, tanks must pick up the Bellows Operators and face them away from the raid to prevent Rugido ensordecedor damage

Damage-Dealer Responsibilities

If targeted by Bomba, or after looting the Cluster of Lit bombs, run to the nearest Heat Regulator and use the Extra Action Button

If targeted by Ruptura, move away from the raid to create the Ruptura zone

Interrupt the Furnace Engineers' Reparar and Feldspar's Piroestallido

Use personal damage-reduction cooldowns if targeted by Bomba just before, or after, a Reventar

Healer Responsibilities

Watch the Heart of the Mountain's Energy bar to predict the timing of Reventar, and use cooldowns or strong AoE healing abilities to counter it

Players with Bomba will take moderate to heavy single-target damage when the Bomba detonates

The half of the raid that is near Foreman Feldspar will take additional periodic damage from Sangre caliente, as well as Ruptura and Piroestallido damage, and will require additional healing

The Feldspar tank will take heavy damage when afflicted with several stacks of Fundir armadura, and may require external CDs

If targeted by Bomba, run to the nearest Heat Regulator and use the Extra Action Button

If targeted by Ruptura, move away from the raid to create the Ruptura zone

Return to Table of ContentsPhase 2: The Heart Exposed

The Primal Elementalists have a Escudo de daño which makes them immune to damage

Players can remove this shield by killing a Elemental de escoria within 8 yards of a Primal Elementalist

One Slag Elemental spawns approximately every 45 seconds

Slag Elementals Fijar random players; the targeted player must kite the Slag Elemental to the Primal Elementalist

Slag Elementals cast Bomba de escoria when they die, dealing damage to nearby players, so ranged DPS should be assigned to kill them at the appropriate time

The Primal Elementalist will gain Escudos inutilizados, becoming vulnerable to damage for a brief window of time

Tank Security Guards and Firecallers a bit away from the current Primal Elementalist target, so the Elementalist is not affected by Defensa

Primal Elementalists and Slag Elementals cannot be tanked

Interrupt Firecallers' Cauterizar heridas and Ráfaga de lava casts when possible; Firecallers can be stunned

Damage-Dealer Responsibilities

Ranged DPS should kill Slag Elementals while they are close to the current Primal Elementalist target to remove the Escudo de daño

Melee DPS should kill Firecallers and Security Guards until a Primal Elementalist becomes vulnerable to damage

Focus all damage on a Primal Elementalist when its Escudo de daño is removed

Interrupt or dispel the Flamecallers' Cauterizar heridas, particularly if it is being cast on the current Primal Elementalist target

Dispel the Primal Elementalists' Escudo de tierra reactivo before it begins to heal

When targeted by a Slag Elemental's Fijar, kite the Elemental to the current Primal Elementalist target

Use a personal survivability CD to mitigate a Slag Elemental's Quemar attack, especially near Reventar

If targeted by Fuego volátil, move away from the raid to avoid injuring other players

Healer Responsibilities

Tanks will take heavy damage and will need dedicated healing

Watch the Heart of the Mountain's Energy bar to predict the timing of Reventar, and use cooldowns or strong AoE healing abilities to counter it

When targeted by a Slag Elemental's Fijar, kite the Elemental to the current Primal Elementalist target

Use a personal survivability CD to mitigate a Slag Elemental's Quemar attack, especially near Reventar

If targeted by Fuego volátil, move away from the raid to avoid injuring other players

Return to Table of ContentsPhase 3: Freedom!FundirFundirFundirReventarAnsia de sangreHeroísmoDistorsión temporalTank Responsibilities

Move the Heart of the Mountain away from any patches of Fundir that spawn nearby

Drag the Heart of the Mountain to clearer areas of the room as Fundir begins to fill up the available space

The off-tank should taunt when the current tank reaches 3 stacks of Calor, or when the off-tank's Calor stacks fall off

Damage-Dealer Responsibilities

Ranged DPS should spread out to limit movement for Fundir

Move quickly out of Fundir if it spawns beneath you

Use personal damage-reduction CDs when Reventar and Fundir damage overlap

Use DPS CDs to defeat the Heart of the Mountain quickly before healers are overrun

Healer Responsibilities

Tanks will take heavy peroidic damage from Calor and may require CDs and dedicated healing

Players who move slowly out of Fundir will take heavy damage

Reventar will occur frequently; coordinate raid CDs to cope with this heavy damage

Return to Table of ContentsLooking For Raid Difficulty

In Phase 1, only 5 Bombas are necessary to destroy each Heat Regulator. Bellows Operators also give the Heart of the Mountain less Heat while they are alive.

In Phase 2, Primal Elementalists are not protected by Escudo de daño, and can simply be killed. Slag Elementals do not spawn.

In Phase 3, Reventars occur less frequently - approximately once every 20-30 seconds. Additionally, the Heart of the Mountain's Fundir pools do not grow in size the way they do in higher difficulties.

Ansia de sangreHeroísmoDistorsión temporalReturn to Table of ContentsMythic DifficultyEscoria endurecida

The only way this can be countered is by having Priests in the raid cast Control mental on the Security Guards; they can then use the Security Guard's Asesinar a elemental ability to remove the Escoria endurecida buff from the Slag Elementals. This allows players to quickly kill the Slag Elementals and break through the Primal Elementalists' Escudo de daño.

This means Reventars will come more frequently during this phase than on lower difficulty levels, and players must defeat Primal Elementalists quickly to save healer mana, which will be needed for the final phase of the encounter.

The raid should be sure to chain Escudos inutilizados phases together on each Primal Elementalist to speed this phase up, and may wish to use Ansia de sangre/Heroísmo/Distorsión temporal here, although it may only help with one Primal Elementalist.

If players allow the Heat to accumulate too quickly in Phase 1, healers will be unable to keep up during Phase 2.

The raid must defeat Bellows Operators swiftly in Phase 1, and destroy Regulators as quickly as possible, to control Phase 2 Blast damage.

Bomba

Players must react very quickly to use an entire Cluster of Lit Bombs.

Additionally, the Bellows Operators will abandon their bellows duties and require tanking upon reaching 50% health, whether the Heat Regulators are disabled or not.

Let's skip this fight wing 2 looks easier.

Comentario de Shrugtal

This fight looks like it's full of a ton of interesting mechanics as opposed to the usual format of handle two mechanics, kill adds and avoid "fire". Can't wait, great guide!

Comentario de 1424640

Now excuse me but why has Blizzard decided to make encounters that force you to take in certain Classes for Mythic progression? Control mental being necessary for the fight on Mythic, and really useful on lower difficulties seems a bit unfair to other Classes. Im not saying this is completely wrong, but it seems a weird thing to do.

Comentario de Keasha

Having two priests for especially P1 is god-mode. Using Dominate Mind will help you spread the bombs in your raid faster and allow to advance into P2 quicker.

If you are having trouble with this fight, search youtube for blast furnace guide live server.
I can't post links yet, because I am new, but I made a thorough guide with a video of a kill on youtube. Hopefully you can find it and good luck killing him.

Comentario de Casn

Notes regearding LFR difficulty are moslty wrong. Heat Regulators on LFR have 499k hp (unless I noticed it wrong and it's 399k) so take 5 bombs, and clusters still drop.
During phase 2 I don't think I've seen even single Slag Elemental, so probably not only shields but also elementals are removed.
During phase 3 Heart does go Superheated, and according to tooltip blasts occur every 6 seconds. Note that at LFR this does not cause so significant raid damage.

As a side note, on LFR Security Guards can be CCed to break their Defense, unless it's not possible to CC them on higher difficulties, that is better way of handling them than moving out.

Comentario de FriendlyFacts

For all you priests out there making full use of their Control mental, there are a few catches to this.

First off, any mob you used Control mental on, will receive the Exasperante buff afterwards. This is permanent and not removable. In other words, you can only mind control a mob once and it should be nuked to death shortly after to avoid unnecessary damage.

Since the first phase is more about control instead of a mad dash to get the Heat Regulator's down, mind controlling the Ingeniero del horno's is generally a waste of effort. However, it does help to end a phase, so with some training and communication you can "force" the phase transition by using Control mental on the Ingeniero del horno's and manually casting Bomba on designated targets. This'll ensure a phase transition when you want it - in a perfect scenario when you've cleared most of the mobs and before new reinforcements arrive.

When the second phase arrives Control mental is a good spell to use on the Guardia de seguridad. There are two abilities not listed on WoWhead, as well as the permanent passive of Mataelementales. The two abilities are a stomp-taunt and a direct damage ability that both only work on Elemental de escoria. The perfect strategy is to mind control a security guard when an elemental is at low health. (Mythic difficulty will do this at full health as to remove the buff). Make sure the Elemental de escoria is near a Elementalista primigenia and then cast the stomp-taunt. Follow up with the Asesinar a elemental. The guard itself will be hitting for a substitutional amount. Melee should move out of range and let ranged DPS finish the Elemental de escoria and let the security guard eat up the Bomba de escoria. If this does not finish off the guard he should be nuked down thereafter.

Clamafuegos's are the final mob that are susceptible to Control mental. Their noteworthy ability of Cauterizar heridas is useless when used on players. However, it can still cast Ráfaga de lava which has a mana cost. It's possible to drain his mana this way, but it only stops future Ráfaga de lava casts for a short while. The primary use of using Control mental on the Clamafuegos is stalling all other instant spellcasts of the Clamafuegos which are not available to the player.

Good luck on using Control mental!

Comentario de AveryZan

I only did this on normal and this was earlier on, it may not work this way any more but it's worth looking into. That defense ability security guards do doesn't seem to work for stationary targets like the bellows/ elementalists (they seem to take full damage while it's up and in it as far as I can tell). Feel free to test and see if you come to the same conclusion.

Comentario de 1194084

Some extra tip:
Elemental de escorias spams Quemar and stay in one place while casting Burn. If you want it to move, just interrupt Burn. The Slag elemental will move towards the player it Fijar, but it cannot do any melee attack.

If you are an MC Priest, move MCed adds near the tank before you drop MC because this makes it easier for tanks to gain threat while adds gain Exasperante once out of MC, immune to taunt and crwod control.

Comentario de xJAMA33x

This really sucks that you have to have a Priest will you on Mythic difficulty for Phase 2: The Heart Exposed. Hope it gets changed sometime in the future so it is easier for people who don't have a Priest.

Comentario de Crook1d

This seems to have been nerfed heavily with patch 7.3.5 on mythic difficulty.

Last week at ilvl 969 it was difficult to solo as a Rogue due to the CD of Bribe (MC). The 5 minute window was rough. I was all prepared for the same thing this week and it was a joke. You don't even need the elementals to DPS the Primal Elementalists even though doing so will be quicker and the elementals don't need their buff removed to damage them adequately.

I don't know if this was intended but it was a joy to solo.

Quick note: make sure you create an LFG group and set the loot to "Group Loot" or "Free for All" otherwise it will automatically be on personal loot even for mythic. This screwed me out of some transmog on the first boss before realizing the 7.3.5 personal loot changes effected even Mythic content for WOD.

Comentario de Ayemes

Since 7.3.5 landed this has been soloable without a priest. The hp scaling has allowed enough damage to be done to negate the damage debuff from the elementalists in phase 2. It will probably still be safe to take a friend for the extra dps but it no longer has to be a priest
