Ignis the Furnace Master - Ulduar boss guide

Tactics for Ignis, Lord of the Forges in Ulduar 10/25 for WoW 3.3.5a: iron creatures, Burn and Heat, Smelting, Brittle and Icing, Slag ladle, zerg strategy and full loot.
Review
Ignis is a fire giant who, on Loken's orders, riveted iron to Veranus (she became Razorwing) and forged Kologarn. Optional boss without hardmode, usually fights second or third. Single-phase battle: the tank leads the boss around the hall, the healers pull out the victims of the Slag Bucket, and the off-tank drives the iron creatures through the fire into the water to smash them and remove stacks of Creator Power from Ignis. With enough weight, all the fuss with the creatures is ignored and the boss simply zerks.
- The Burn and Fire Stream cast is directed at the current target, so the boss is ALWAYS facing away from the raid - a 30-meter cone.
- Fire Stream: cast for 2.7 sec, throws up and locks the school for 6 sec - casters interrupt the cast in advance, rather than pray.
- A tank in water extinguishes the Burn instantly: convenient for the zerg, but then the creatures have nowhere to gain Heat. Choose one.
- The Frost threshold is different: 5000 damage with one hit in spell 10 (spell 62382) and 3000 in spell 25 (spell 67114). If you don’t achieve it, the fragility will fall off and it will all happen again.
- Achievement “Stokin' the Furnace” - kill Ignis in 4 minutes; in the script this is a timed achievement at the start of the battle.
- Achievement “Shattered” - shatter two creatures within 5 seconds (in the script there is exactly 5000 ms between two Icings).
- Desecrated ground unholy-DK extinguishes the Burn under creation - do not place unholy-DK on adds.
- Ignis significantly reduces fire damage: it makes sense for fire mages to go to FFB.
Combat phases
The combat is single-phase, but with two parallel conveyors. First: the main tank keeps Ignis facing away from the raid, takes him away from the scorched earth and worriesBurn every 20 sec andFire Stream every 25 sec while the healers pull outSlag ladle every 24 sec. Second: every 40 sec (10) / 30 sec (25) Ignis activates one iron creature and receives a stack ofCreator's Powers (+20% damage). Off-tank drags the creature into a puddleBurn → 10 stacksHeat → Melting → into the water →Brittleness → range hits 5000+ (3000+ in 25) →Icing, the creature scatters and a stack falls from Ignis.
- The boss always faces away from the raid
- Interrupt your castes beforeWith a stream of fire
- Heal the victimSlag ladle
- Cycle creation → fire → water → finish off
- Fresh puddleBurn under adds
Abilities
Positioning
Classic: The main tank drives Ignis in a circle or triangle at the water's edge, facing straight away from the raid, leaving Burn puddles a mile away. Range and heals stand in the water or at the very edge. The off-tank works as a shuttle: picks up the creature → into the nearest puddle → into the water → moves away → the assigned range finishes off. Zerg option: the tank stands right in the water, the Burn goes out on the spot, the adds are simply collected in a heap and not touched at all.
Role Tips
- Don't plant unholy-DK on adds: Corrupted Earth extinguishesBurn under creation andHeat not dialing.
- DK's Ice Shackles and Warrior's Stunning Strike make it much easier to guide a creature through a puddle.
- After Ignis's dash for a scoop victim, he often ends up in a stupid position - return him immediately while the cone is not facing the raid.
- If you want zerg, tank the boss in the water:Burn goes out on the spot, but then the creatures have nowhere to typeHeat, and stacksCreator's Powers will accumulate.
- Slag ladle requires an individual: 4500 (6000 in 25) damage per second for 10 seconds - without focused healing, the rag cannot survive.
- Stand in the water: after the aggro is released, the red-hot creatures will come running to you, and OT will finish the cycle faster.
- StuckeyCreator's Powers they accelerate the physics on the MT like an avalanche - if the adds are not hit, plan the tank’s CD in advance.
- Cancel cast beforeFire stream:Locking the school for 6 seconds in the middle of the bucket kills the raid.
- Don't waste damage on iron creatures - they are only killed byIcing, everything else goes into milk.
- One designated range with a big poke finishesBrittleness: 5000+ with one attack in 10, 3000+ in 25.
- It makes sense for fire mages to go into Ice Arrow: Ignis has noticeable resistance to fire.
- Rogi: Cloak of Shadows removes the bucket pillbox completely. Magi: Ice block. Paladins: the shield will save you, but will ruin your achievement.
- Opening the Rogue and Druid's Faerie Sense on the boss is a very noticeable increase for melee.
