Grim Batol Walkthrough.

Grim Batol

General Umbriss

Normal:  Spread out during this fight, the boss will charge a random person, whomever he charges must move away from where they were standing otherwise the boss will one shot them. Every so often a purple Trogg will come down called a Malignant Trogg. When it is killed it will give a debuff those who where near it that does a high amount of DOT damage. Get the purple one away from the tank and boss and kill it, try and keep it away from you as you kite it, if the boss gets the debuff due to the trogg dying near it he will go into a frenzy which will pretty much 2 shot the tank. AOE any other Trogg down. At the end of the fight he goes into a frenzy, pop heroism and burn him before he kills you.

Heroic: Does the same as normal plus a Ground tremor, move away from the tremor.   

Forgemaster Throngus

Normal and Heroic: Watch for falling rocks, don't stand under them.
He has 3 different weapons, A mace, a Sword, and a shield. He is different depending on the weapon he chooses at random

The Mace: He is slowed, kite him around, range need to watch agro in this phase. He will also drop fire paths on the ground, don't stand in them and move away if they come at you. He will jump on random people and impale them, healers need to heal those who are impaled.

The Sword: Does massive damage to the tank, also casts a debuff on the tank which needs to be dispelled as soon as its up.

The Shield: He will face a direction and cast a flame cannon in front of him, get out of it and go behind him, it can kill anyone in it for more then 2-3 sec, he will change direction so keep moving and stay behind him. He also casts flares that will hit the group for mild damage, heal through this.


Drahga Shadowburner

Normal and heroic: He can be tanked easy, every so often he will summon a fire add that will chase a random player. They must be slowed or rooted and then killed before they reach their target, if they reach them they will do a large fire attack that can kill the target and possibly those near him.
He will eventually jump on a Twilight Dragon, he will do the same summoning ability as before, but the dragon now also drops flame pools on the ground as well as a focus breath that must be moved out of.
After she gets to around 20% health she will ditch the Warlock and fly away, goes back to phase one, kill him.

Erudax

Normal and Heroic: The boss will target a player at random and cast Binding shadows, that player needs to move from where they were standing, if they do not they will be hit for quite a bit of damage and heal the boss.  Always tank him in the middle, he will do a knockback that will also give you a debuff that will increase damage taken by 100% for 3 seconds. So use the time it takes for him to run up to you after the knockback to let the debuff drop. He will eventually start casting Shadow gale, when he does this a purple circle will show up somewhere in the area, everyone needs to be in it, it acts as the eye to the gale.  After he finishes casting Gale, he will summon two faceless one adds, split DPS and kill them before they finish channeling on the eggs, they can be slowed, so try that before they reach the eggs. If the eggs hatch they spawn Dragon adds that will heal the boss, take them down if they spawn, note that too many of those will make this fight last longer than your healers mana pool.
Make sure to attack him as much as you can when he casts Gale, he takes lot of damage during this.
Make sure as soon as the gale ends that you spread out fast, otherwise the binding shadows can hit the whole group which will heal him to full.
