Halazzi - Lynx Avatar
This boss has a tiny amount of hp, roughly 600k. This is a 2 phase encounter that rotates (similar to Nightbane) every 25%.
Phase 1 -
He hits quite hard and also does a Mother Shahraz type of ability like Saber Lash that if it hits more than 1 person the damage received by each person is much less than if it were to hit only 1. Once you get him to 75 % he will go into phase 2.
Phase 2 -
During this phase he will transform back into his Shaman form and spawn a Spirit of the Lynx that has approx 200k hp. Also during this phase he will drop a nasty totem known as: Corrupted Lightning Totem that does chain lightning for approx 5k, maybe some nat res is not a bad idea, but not a necessity. The last ability of this phase is a Flame Shock that he will do randomly to 1 target.
Basically tank and spank in phase 1. When phase 2 occurs, 1 tank stays on the Shaman and the other tank takes the Spirit. You need to dps down the Spirit as fast as possible so you will not stay in phase 2, too long because of the nasty totems.
Kill the totems when they spawn (similar to Tidvalas during the Fathom Lord Karathress encounter in SSC), cleanse people if needed. Rinse and repeat till dead.
