Warchief Rend Blackhand

The Rookery and Blackhand Stadium
Cross the Rookery along a cleared edge without walking through the eggs, then continue through the Hall of Blackhand to the Stadium. Bring everyone down into the arena before starting its event. Handle the incoming orcs and dragonkin before Gyth arrives carrying Rend; have the second tank ready for Rend's dismount while the first still holds Gyth.

Abilities

Freeze
Sends out an ice blast that stuns and damages enemies in a cone in front of the caster, then inflicts additional Frost damage every 3 sec. for 10 seconds.
Gyth's Freeze stuns and damages players in a frontal cone. Leave that cone to his tank instead of standing beside the tank when Rend dismounts.

Corrosive Acid Breath
Shoots a cloud of acidic breath at enemies in a cone in front of the caster, reducing their armor and inflicting Nature damage every 5 sec. for 30 seconds.
Keep Gyth's Corrosive Acid Breath directed away from the group; the armor loss and Nature damage make a shared frontal position dangerous.

Flame Breath
Gyth's Flame Breath also hits a frontal cone. Keep his facing stable while the other tank collects Rend.

Whirlwind
Leave Rend's melee area during Whirlwind and return after the spinning attack ends; the second tank should keep him apart from Gyth during the overlap.
Tank- Keep the first tank on Gyth with every frontal breath facing away from the arena group. The second tank collects Rend on dismount and separates him from Gyth without turning the dragon through the healers.
Healer- Account for the armor loss from Gyth's Corrosive Acid Breath and the period when both tanks take hits. Keep a position outside both Gyth's cone and Rend's Whirlwind.
Damage- Finish Gyth while the second tank holds Rend. Stay away from Gyth's front, then withdraw from Rend's Whirlwind instead of continuing melee attacks through it.
