General Bjarngrim

1. The hardest part of this fight is pulling him. You need to pull him when his buff is off.
2. The tank must face him away from the party and the melee must move during his whirlwind.
3. He does a mortal strike, so healers need to be topping the tank off at all times.
4. Kill down the adds fast, they will heal him.

Volkhan

1. Nothing special here besides his summoning of golems. The golems will freeze at 1% health, when he is casting his stomp you need to run very far. The golems will shatter and do very heavy damage to everyone.

Ionar

1. Have the group spread out to avoid ball of lighting which is cast on a party member and hits anyone within 10 yards.
2. When he splits into lightning balls make sure everyone stays away from them.

Loken

1. You need to watch out for his lighting dot, it will jump to nearby members.
2. The hardest part of the fight is when he casts Lightning Nova, at this point everyone has to stop dpsing and run very far away, the tank included. If you do not get out of range you can die pretty easily, if you get this down he isn't too hard.
