Watchkeeper Gargolmar

Abilities

Surge - Charges a randomly selected party member for 300-600 damage, causes knock down effect on target.

Unprepared - Once Gargolmar reaches 50% HP he will yell for healing from his minions.

Fight

Gargolmar patrols back and forth, make sure to clear the trash and adds throughout his patrol route before engaging him. Once you've double checked the path as clear have the tank pull him, he has two guards as well, Hellfire Watchers, take them out before fighting Gargolmar.

As with the other bosses spread out the ranged classes to prevent multiple members from being hit with the surge/charge attack.

Omor the Unscarred

Abilities

Summon Hound - Omor will summon his fel hunter hound throughout the fight, kill it.

Treacherous Aura - Curse Aura, repeatedly deals 360-440 shadow damage to anyone within 15 yards, removable.

Fight

Spread out around Omor, this allows you to nullify the effect of his 15 yard range aura on all except the melee. Omor will summon his fel hunter pet periodically during the fight, keep a hunter or any other DPS class on hound duty to negate this weak summon.

Besides the pitiful hound summoning and the rather weak aura Omor is a piece of cake, eat him.

Vazruden The Herald

Abilities

Allies - A Dragon and a couple of sentries

Fight

Vazruden is pretty easy, just kill his sentries, him, then move onto the dragon. Keep in mind both sentries can be CC'ed so sheep one, drop the other, then kill the last. Afterwards drop Vazruden before killing his dragon.

Nazan, The Dragon

Abilities

Fireball - Nazan will shoot fireballs at random party members dealing around 850-950 damage. Each fireball will cause a small fire patch at the location it hits dealing 400 damage a second within a small radius.

Fire Cone - Small close range cone attack, hit's whoever has aggro also leaving the fire patch same as the fireball.

Fight

Nazan is killed after Vazruden, the rider, he should be moved to the center of the platform allowing the party to surround him and spread out. Your tank will need to move each time the dragon fires off a cone of fire/fireball to avoid the fire patch, just have him go clockwise/counter-clockwise.

Everyone else just needs to move if he throws a fireball at them, this fight's rather easy.
