The Blast Furnace

The Blast Furnace

Blast Furnace

The Blackrock clan’s unique ability to smelt the black ore, a substance so dense that ordinary flame does not even soften it, has always been their most closely-guarded secret. Deep within the Foundry, their furnace contains a primal force as old as Draenor itself, raging within the confines of its prison as it emanates a prenatural heat.

Healing Strategy

Blast furnace

Heat regulatorThis is an add fight of epic proportions. The encounter is split into three phases. In the first phase your goal is to handle adds and carry bombs to the Heat Regulators. Once the Heat Regulators have broken down, you enter phase two where you have to kill four Primal Elementalists that try to control the Heart of the Mountain. Once the Elementalists are dead, you enter phase three where you directly engage Heart of the Mountain and all hell breaks loose. Meanwhile you have to manage the miniboss Foreman Feldspar, adds, bombs and debuffs during the entire fight.

Phase One; SABOTAGE
Objective; Destroy the Heat Regulators

Drop Lit BombsYou start the fight by engaging Foreman Feldspar and the accompanied adds. The raid should split into two group and position themselves on each side of Heart of the Mountain’s prison. On each side of the prison there is a Heat Regulator with a health pool, which should be destroyed with bombs. You acquire the bombs in two ways; either having a Furnace Engineer cast a inv_misc_enggizmos_35Bomb at you or pick up the inv_misc_bomb_05Drop Lit Bombs which the engineers drop once they die. Either way, when a Bomb has been thrown or dropped by the Engineer, it gets a timer. Once the timer goes off it explodes. Players should either carry or pick up bombs to the Heat Regulators before they explode. You drop/explode the bombs with the Extra Action button.

Furnace Engineers will also try to inv_misc_wrench_01Repair the Heat Regulators, and they must be stopped quickly with a stun or an interrupt. Engineers are high priority targets when they try to repair the regulators, otherwise damage-dealers should always prioritize Bellows Operators.

Bellows Operators are the big ogrons that will constantly try to increase the Heat level of the Furnace. If the Operators are allowed to increase the heat level, the Heart of the Mountain’s energy regen will increase and you will get ability_foundryraid_blastwaveBlast from the imprisoned fire elemental more often. Blast is an unavoidable raid-wide damage that the Heart does at 100 energy, which will put the healer’s mana to the test. To avoid completely draining healer’s mana, the Bellow Operators must die quickly. They will continually spawn in the first phase.

DefenseBeside from Furnace Engineers and Bellow Operators, you will also have to deal with Security Guards. These will ramp up the damage on your tanks and also occasionally drop their shields to do inv_shield_32Defense, which creates a safe-zone for any of the add’s allies. Tanks must kite the adds away from the Defense shields to avoid the immunity buff on the adds.

One of the two raid groups will also have to deal with the miniboss Foreman Feldspar. Feldspar has an aura called ability_racial_bloodrageHot Blooded which causes fire damage to neary players. He will also put a debuff called ability_rhyolith_magmaflow_wholeRupture on random players. Once the debuff has reached the end of its duration, it will leave a puddle of magma below the affected player. Players who are affected by Rupture must place these magma pools at the walls of the room to avoid cluttering the entire room.

Feldspar’s third ability is spell_shaman_lavaburstPyroclasm, which does high damage to random players unless it is interrupted!

Once the Heat Regulators have reached 0 health, you will transition to the second phase. Make sure you have as few adds as possible when entering phase two. The Bellows Operators are particularly dangerous. Their frontal cone attack ability_fomor_boss_shoutDeafening Roar, which they only do if they are carried to phase two, could potentially kill players. Make sure the Bellows Operators are killed just before the Heat Regulators are destroyed.

Second Phase; THE HEART EXPOSED
Objective; Kill the four Primal Elementalists

Phase twoOnce you enter phase two, the Heart of the Mountain has escaped its prison but is controlled by four Primal Elementalists (if you haven’t killed Foreman Feldspar yet you must do it quickly in this phase).

Your job is to kill the Elementalists to be able to engage the Heart of the Mountain directly, but it is not as easy as it sounds. The Elementalists have the ability inv_misc_enggizmos_15Damage Shield that makes them immune to all damage. The only way to disable the shields is to kill one of the spawning Slag Elementals within 8 yards of the Elementalist. Once the Slag Elemental dies close to the Elementalist, its shields go down and it is vulnerable to damage. Damage-dealers have a small window to kill the Elementalist before the shields are up again, and you have to repeat the process.

Slag Elemental
Slag Elemental

Slag Elementals will spawn at a steady rate and fixate on a random player. The fixated player must kite the Slag to the Elementalist and stand within the 8 yard range without standing in the fire. When they die, or go dormant, they will also explode, 6bf_explosive_shardSlag Bomb, which causes very high damage to all players within 8 yards. Players who can should avoid the explosion.

The Primal Elementalists will also cast item_earthenmightReactive Earth Shield on themselves that will heal them if it isn’t offensively dispelled within 8 seconds. Purge, Dispel Magic and Tranquilizing Shots are examples of abilities that work.

Security Guards will also continue to spawn in this phase and drop their Defense zones. Slag Elementals gain immunity from Defense (but Primal Elemenatlists don’t), so the whole raid should be attentive to kite out any Slag Elementals from the zones.

Volatile Fire
Player debuffed with Volatile Fire

A new add will also join the fight in this phase; Firecallers. These buggers will cast the debuff spell_fire_lavaspawnVolatile Fire on random players, which will then explode after 12 seconds. Affected players should run out of the raid to avoid spreading damage. They will also try to heal an ally with spell_fire_burnoutCauterize Wound, occasionally on a Primal Elementalist you are trying to kill, which should be interrupted. spell_shaman_lavaburstLava Burst is another spell they cast which hits a random player. This can also be interrupted!

In this phase you can choose to still have the raid split and work on two Primal Elementalists at the same time. The other option is to gather the whole raid to one group and work collectively at one Primal Elementalist at a time. The goal is to be fast enough so that you only need to use one Slag Elemental per Primal Elementalist. This means that damage-dealers must burst when the shields are down, interrupt Firecaller’s Cauterize Wounds and dispel Reactive Earth Shield to avoid having them healed.

Meanwhile, the Heart of the Mountain will continue to do Blast. It will also be chained to a pool in the middle of the room called inv_misc_ring_firelands_3Slag Pool, which increases the Heart’s heat level while it stands in it. The Heart will stand in the Slag Pool the entire second phase, continuously increasing its Heat level which in turn increases the rate which Blast comes out. If you spend too much time in the second phase, the Heat level and the subsequent Blasts will be too much for healers to handle. The second phase must be as short as possible!

Once the four Primal Elementalists are dead, the Heart of the Mountain breaks free and you can engage it directly.

Phase Three; FREEDOM!
Objective; Kill the Heart of the Mountain

Before you focus the Heart of the Mountain, all remaining adds should be killed as quickly as possible. Once they are dead you only have to deal with a few abilities from the Heart of the Mountain.

MeltIt will periodically cast ability_foundryraid_meltMelt on random players, which leaves a pool of magma. These can quickly become a bother for manoeuvring, so players should position themselves so that the magma pools will be placed out of the way for future movement (a.k.a. don’t lock yourself in by a wall of Melt). The raid has to move at a slow rate to avoid the magma pools.

Tanks will have a tank debuff to deal with; inv_ammo_firetarHeat. They should swap at 3 stacks and healers should be really attentive to the tanks, since Heart of the Mountain will still do Blast and it does more damage to players affected by Heat.

In this phase you are racing against the rate of which healers’ mana pools are depleted. Blast will come often and require much healing to counter. If the previous phases were dragged out, healers might not have enough mana for this phase.

Cast Bloodlust, Heroism or Time Warp at the beginning of this phase and kill the Heart of the Mountain before the healers run out of mana.

Mistweaver Specifics 2
Since this is such a long and mana draining fight, you should probably go with Chi Torpedo instead of Rushing Jade Wind. Xuen can be used on the adds, but you will have a more steady healing output from Chi Torpedo, which is good since the damage output from Blast and other abilities will be quite consistent. Also make sure you use your free spells as often as possible. Chi Burst and Zen Sphere could both work and grant additional healing without taxing your mana.

If your raid is struggling with killing adds, especially the Primal Elementalists, Mistweavers should help out in Crane stance. Pool of Mist is the best talent for Stance dancing (but Chi Explosion is better if you want to spend more time in Crane). Rising Sun Kick can do quite a lot of damage, and with Pool of Mist you can burst with the three available stacks of the ability. Your free talent spells can also pack quite a punch.

The best spell for this encounter is however Touch of Death. If you are progressing Blast Furnace, often the main reason for wipes is that the phases are dragged out. Help your raid by quickly finishing off adds such as Bellows Operators and Primal Elementalists with a quick execute.

As for defense, pretty much everything is Fire damage. Use Diffuse Magic to protect yourself from Bombs, Blast and Volatile Fire. Fortifying Brew should also be used whenever you feel that you are in danger.

Serpent Tactics 2

Phase One

  • Heart of the Mountain will do ability_foundryraid_blastwaveBlast each time it reaches 100 energy, which does raid wide damage. The energy rate will increase if the Heat level is increased. Blast will occur during the entire fight and can potentially become really difficult for healers to heal through if the fight is prolonged.
  • If inv_misc_enggizmos_35Bomb is cast on you by the Furnace Engineers, drop it by the Heat Regulators.
  • Pick up any inv_misc_bomb_05Drop Lit Bombs and bring them to the Heat Regulators.
  • If debuffed with ability_rhyolith_magmaflow_wholeRupture, run out to the sides of the room and place the spawning magma pool close to the walls, out of the way.
  • Don’t stand in pools created by Rupture.
  • The tank that also tanks Foreman Feldspar will take extra damage, both from melee attacks and the ability_racial_bloodrageHot Blooded aura.

Phase Two

  • If fixated by Slag Elemental, run to the focused Primal Elementalist and place the Slag close to it without standing in any inv_shield_32Defense zones.
  • If you get the debuff spell_fire_lavaspawnVolatile Fire, run out of the raid before it explodes (12 sec duration).

Phase Three

  • Tanks will take high damage during Blast because of the tank debuff inv_ammo_firetarHeat.
  • Don’t stand in ability_foundryraid_meltMelt pools!
  • Use Diffuse Magic (Talent)Diffuse Magic and Fortifying BrewFortifying Brew to save yourself when the damage from Blast starts to reach dangerous levels.

Crane tactics 2

  • It is really beneficial to start the fight in Crane stance and swap to it at several points in the fight to have a mana regen that can cope with the long and intensive fight.
  • If you are able, help damage-dealers burst down the Primal Elementalist in phase two, once their shields are down.
  • There are many spells a Crane healer could help interrupt;
    • Furnace Engineer’s inv_misc_wrench_01Repair
    • Foreman Feldspar’s spell_shaman_lavaburstPyroclasm
    • Firecaller’s spell_fire_burnoutCauterize Wounds and spell_shaman_lavaburstLava Burst
  • Execute important adds such as Bellows Operators, Engineers and Primal Elementalists with Touch of DeathTouch of Death.
