Hellfire assault can be looked as the new Galakras fight.
There are a few things worth going over.
Our goal is to break the door that leads us to epic phat loot. The way we do this is by killing alot of adds and different siege vehicles.
Types of adds
Siegemaster Tar'mak - has different abbilities and will be burned down (focused) at the start of the fight
Iron dragoon - Random add, cleave it with the rest of the adds
Hulking Beserker - Big beserker, the two tanks will be tank swapping since he has a debuff, cleave with the rest of the mobs.
Gorebound Felcasters (PRIORITY) - these adds cast different abilities, the main one being the volley, we want that interrupted asap to avoid raid wide damage. at 30% HP the add will transform into a metamorphis and start doing uninterruptable volleys until it dies. these adds will be marked with a skull and will have prio so as soon as it turns we kill it.
Note that WE DO NOT want to have two metamorphised adds up at the same time, so if there's two felcasters up we push one down and kill it before killing the next one.
Engineer - Small goblin creatures that will be cleaved with the rest of the adds. The difference here is that the engineers will be casting bombs on the ground so make sure you get away from those before they explode.
Siege engines (PRIORITY) - These siege engines only goal is to stop us from breaching the door, meaning that the will try to stop the cannons we are using. These together with the felcasters will always be our priority, mainly siege engines though. There are different types, and will get explained in the raid rather than here (Please do read up on them in the dungeon journal)
Way we deal with the fight
The fight is done in two phases.
Phase 1 starts off with siegemaster Tar'mak and one each of the adds, we will nuke down Tar'mak (HEROISM) before dealing with the rest of the adds, after that we kill the adds in the order we need to starting phase 2
Phase 2 is a simple Galakras add fight, we deal with the various adds in the order and priorities. every 45-60 seconds a siege engine will show up, we will nuke the siege engines. The siege engines are dropping ammunition that we need for our cannons. We will most likely have Ollopa picking these up or Zerach. we simply rince and repeat until the door is broken and we have beaten the encounter
Siege Engine (when up)
NOTE: Beserkers, Engineers and dragoons will be cleaved down.
simple straight fight with alot of adds, as long as we make sure that we kill felcasters nice and easy along with siege engines it will be a easy kill.
