The Encounter

Ignis the Furnace Master is a standard tank and spank encounter with the only difference of the iron constructs which need to be heated until they melt and cooled down in water.

Tactic and Setup

He will cast Scorch from time to time, which leaves an ground area of effect. Now your task is to kite the iron constructs into this ground area effect. As long the iron constructs are in this aoe effect, they will get a heating buff. Once the buff stacks up to 20, they will be melting.

When they are melting, they will do damage in a 7 yard area (~5.000 damage every second). So make sure no one stays to close to them. If there are more Iron Constructs active, tank them away from each other.

Now you have to pull/kite them into the water, which turns them brittle. This will stun the iron constructs and increase the critical chance against them by 50% and they will shatter, if they are hit for more than 5.000 damage with a single ability.

Be aware: When the Iron Construct shatters, it will deal around 20.000 damage in 10 yard radius. So no melees should be around it, after they got brittled! Only ranged Damage dealers (preferrably Mage, Warlock or Moonkin who have High-hitting spells)

For every shattered construct, one buff stack will be removed from Ignis, reducing his damage.

Caster should watch for Flame Jets and avoid being hit as it will cause a school lock for 8 seconds (same as counterspell).  That's basically all
