Let's skip this fight wing 2 looks easier.

Comment by 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!

Comment by Fishybusiness

Now excuse me but why has Blizzard decided to make encounters that force you to take in certain Classes for Mythic progression? Mind Control 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.

Comment by 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.

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.

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

First off, any mob you used Mind Control on, will receive the Infuriated 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 Furnace Engineer'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 Mind Control on the Furnace Engineer's and manually casting Bomb 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 Mind Control is a good spell to use on the Security Guard. There are two abilities not listed on WoWhead, as well as the permanent passive of Elemental Slayer. The two abilities are a stomp-taunt and a direct damage ability that both only work on Slag Elemental. 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 Slag Elemental is near a Primal Elementalist and then cast the stomp-taunt. Follow up with the Slay Elemental. The guard itself will be hitting for a substitutional amount. Melee should move out of range and let ranged DPS finish the Slag Elemental and let the security guard eat up the Slag Bomb. If this does not finish off the guard he should be nuked down thereafter.

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

Good luck on using Mind Control!

Comment by 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.

Some extra tip:
Slag Elementals spams Burn 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 Fixate, 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 Infuriated once out of MC, immune to taunt and crwod control.

Comment by 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.

Comment by 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.

Comment by 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
