Information

Ignis the Furnace Master is located in the Colossal Forge of the Siege of Ulduar.

The fight will begin as a simple tank 'n spank, where only the spellcasters will need to watch for the 2.7 seconds cast on Flame Jets, and make sure their spells don't get locked out. The tank will need to move out of Scorch and scorched grounds, always facing Ignis away from the raid, and healers will need to be swift healing whoever is in the Slag Pot.

Soon after the beginning of the fight, Ignis will start activating Iron Constructs in the room. Offtank(s) will need to start picking them up, and bringing them over a scorched ground so they can Heat up. After an Iron Construct has become Molten, it should be brought to one of the water pools in the room, and quickly destroyed away from other players and Brittle Constructs. A ranged DPS may been to help Shatter the Brittle Constructs.

Boss Abilities

Constructs

Iron Constructs can be in one of three states once they start their cycle: Heated, Molten, or Brittle. Each follows the other and is brought about by sitting the Iron Construct in a Scorch fire and then, once it is Molten from a full stack of Heat, moving it to Water which will cool it and make it Brittle.

• Heat: Blasts all nearby Iron Constructs with intense heat, increasing their movement speed by 5 and haste by 5. This effect stacks up to 20 times (10 times in normal-mode). If this effect reaches the full stack, the affected Iron Construct will become Molten.

• Molten: The caster becomes Molten, increasing haste by 100%. In addition, Flames errupt out from the caster every second, dealing 4713 to 5287 Fire damage to enemies within 7 yards. Haste increased by 100%. Deals 4713 to 5287 Fire damage to nearby enemies every 1 sec.

• Brittle: The cold water causes molten Iron Constructs to rapidly solidify, rendering them unable to act. In addition, if they are dealt more than 5000 damage during this state, they will shatter, dealing 18850 to 21150 damage to all enemies in a 10 yard radius. Stunned. Chance to receive critical hits increased by 50%. Shatters if dealt 5000 damage or more in a single attack.

• Shatter: Deals 18850 to 21150 Physical damage to all enemies within 18850 to 21150 yards. Damage from this effect ignores armor.

• Strength of the Creator: Increases damage done by 15%. One stack of this buff is applied each time an Iron Construct is summoned, and one stack is removed each time a Brittle Iron Construct is shattered.

10-man

• Scorch: Fires a jet of flame, burning all enemies in front of the caster within 30 yards, dealing 2357 to 2643 Fire damage every half-second for 3 sec. Additionally, the ground is scorched by this effect causing it to catch on fire, dealing 3299 to 3701 Fire damage every second to all enemies within 13 yards. Iron Constructs within this radius will begin to heat up, eventually becoming molten.

• Flame Jets: Stomps the ground causing geysers of flame to erupt under all enemies. These geysers deal 5655 to 6345 Fire damage, knocking the targets into the air and interrupting any spells being cast for 8 sec. In addition, the targets take 1000 Fire damage per second for 8 sec.

• Slag Pot: Charges and grabs a random enemy target, tossing them into the caster's slag pot. The target is unable to attack the caster and takes 3500 Fire damage every second for 10 sec. If the target survives, they are imbued with the magical slag, increasing their haste by 150% for 10 seconds.

• Activate Construct: ?M HP. For every second that a construct is in a Scorch area it gains a stacking speed buff. At 20 stacks it will turn Molten. When Molten it will gain extra haste and deal 2357 to 2643 Fire damage to enemies within 7 yards. Running the construct into water while Molten will turn it Brittle, stunning it, increasing its chance to be critically hit, and causing it to shatter if hit for more than 5000 damage in one attack.

25-man

• Scorch: Fires a jet of flame, burning all enemies in front of the caster within 30 yards, dealing 3770 to 4230 Fire damage every half-second for 3 sec. Additionally, the ground is scorched by this effect causing it to catch on fire, dealing 3299 to 3701 Fire damage every second to all enemies within 13 yards. Iron Constructs within this radius will begin to heat up, eventually becoming molten.

• Flame Jets: Stomps the ground causing geysers of flame to erupt under all enemies. These geysers deal 8483 to 11198 Fire damage, knocking the targets into the air and interrupting any spells being cast for 8 sec. In addition, the targets take 2598 Fire damage per second for 8 sec.

• Slag Pot: Charges and grabs a random enemy target, tossing them into the caster's slag pot. The target is unable to attack the caster and takes 5000 Fire damage every second for 10 sec. If the target survives, they are imbued with the magical slag, increasing their haste by 100% for 10 seconds.

• Activate Construct: 3.81M HP. For every second that a construct is in a Scorch area it gains a stacking speed buff. At 20 stacks it will turn Molten. When Molten it will gain extra haste and deal 4713 to 5287 Fire damage to enemies within 7 yards. Running the construct into water while Molten will turn it Brittle, stunning it, increasing its chance to be critically hit, and causing it to shatter if hit for more than 5000 damage in one attack.

Strategy

• The Ignis encounter is an endurance fight with a soft enrage (not a timer) that makes up the complexity of the fight and affects all members of the raid.

Tanks

Choosing tanks

For all modes, you will need a Main Tank to kite Ignis, and either an off-tank or a very skilled kiting DPS (probably two or even three on 25 man). If you attempt to turn the Iron Constructs molten and destroy them, you'll probably prefer an off-tank because of the mitigation and large buffer of health compared to a DPS. However, if you are going to simply DPS him down immediately (you will need to average about 3500 dps on 10 man for all 5-7 DPS), you can get away with a player who is able to aggro, dodge, and CC the constructs (prot warriors, prot paladin, mages, hunters with a pet, warlocks with a voidwalker, or a druid). Also, the contracts can be snared into place so any kind of druid is the best option.

How to tank

As the main tank, have a hunter misdirect the boss to you, or simply run up and get aggro on him immediately. You should choose and make known which direction or area of the room you're going to kite him so the rest of the raid knows where to position themselves. Some groups choose to strafe him left to right (either across the room, or length wise near the constructs), around the entire room, or around one half of the room; note that he should never be tanked in front of the water if you are going to be destroying the constructs, as scorch will be dispelled. However, this is the optimal location for tanking him to reduce damage on the tank, and keep everyone in the same position throughout the fight.

The second way to tank him is to bring him to the direct center of the room. Have the tank turn him away from the raid and when he scorchs the ground, turn him to the left or right and keep the melee DPS where they are. Then, after then 2nd scorch run aross the boss and tank him in the opposite direction so the 3rd scorch goes to the right or left and the melee DPS can stay where they are. After the 3rd scorch comes, the 1st one should be down by now and you go back to the starting point. If done right, no one should take any damage from contrucsts blowing up nor should they lose Heat stacks. The off tanks should be ready to taunt them to water when they go molten and get out of the way of them blowing up.

Main Tanking - what to look out for

Naxxramas geared tanks (item levels 200 and 213) can take upwards of 25000-30000 damage per hit from Ignis' melee strikes. As the fight goes on, his melee strikes will gain an additional 15% damage from each Iron Construct that is active (eventually, if left unchecked, it will get to the point where you are one shotted). His scorch is a cone that will damage anyone he is facing, so your back should always be away from the raid. Flame Jets will throw you into the air briefly, but since you aren't a caster, your abilities should not become locked. After a scorch has landed on the ground around you, strafe out of it quickly to avoid taking damage and get your melee DPS into a safe spot as well. You should not aggro any constructs unless you wish to cause additional stress to your healers.

Off-tanks and kiters

For the first 15 seconds of the fight, DPS Ignis. He doesn't have a cleave, and scorch won't be fired until 12 seconds into the fight (and you can stand behind him safely). When the first Construct appears, grab aggro and begin moving away from it. The more constructs that are up, the faster they move so eventually they will outrun you if you don't do anything about it. Off-tanks should only take about 1-2k damage per swing, so the damage they deal is negligible, however, since this affects your healers, if you can do something about it you should (as a prot warrior, you can charge constructs and then run past them, or intervene to a close ally to get away from enemies). If you're kiting them and you're not a tank, CCing abilities are vital to your group's survival. Frost Nova, Frost Traps and pet tanks, Void Walkers and destruction warlocks' AOE stun, and druid roots and travel form are all possible solutions, however they tend to only be effective for a few minutes. If your group is going to be destroying the Constructs, make sure you have a healer that can either heal you through scorch, or you have good CCers that can keep the constructs in the flames of scorch long enough to heat it up (moonkins and mages are very handy for that).

Mages or Warlocks assigned to the Construct Squad should immediately wind up their largest spells on the Construct - either Pyroblast for a mage, or Soulfire or Immolate + Conflagration for a warlock.

Healers

Healers need to be on the ball to keep the main tank healed because of the significant melee damage dealt by Ignis. Casters, particularly healers, should take care to stop casting before Ignis uses Flame Jets, otherwise they will be locked out of their spells for 8 seconds. All players should make sure to move out of Scorch areas. Random players will periodically be charged and placed in the Slag Pot attached to Ignis' stomach. Whichever player is charged should be healed through the DoT (they gain a debuff to help identify it on your raid frames). You should instruct your raid members to stack on you for AOE healing.

DPS

As a DPS, your job is to not stand in scorched areas, to call out when you are inside of the Slag Pot, and stand behind Ignis at all times (preferably stacked on your healers for AOE healing). Ranged DPS should be used to destroy Brittle Iron Constructs if your raid decides to kill the adds (only powerful abilities like Chaos Bolt, Frost Fire Bolt, Pyroblast, Aimed Shot, and Starfall should be used to beat the 5000 minimum damage requirement). If you survive being stuck in the Slag Pot, you should use the haste buff as best you can (10 second duration) to fire off your slower, more powerful attacks. Since this fight is heavily reliant on DPS, every DPS member of the party should have a minimum of 3500 DPS (4000+ group average recommended) for the duration of the fight.
