Legendaries: [Thraxsi's Tricksy Treads] & [Will of Valeera]

Nythendra mechanically is a very simple boss. She repeats the same two phases. Active and Heart of the Swarm.

--While active she casts 3 abilities. [Rot], [Volatile Rot], and [Infested Breath] which all leave pools of [infested Ground].

[Rot] - Deals ticking damage and at the end of the debuff leaves a pool of [Infested Ground]
[Volatile Rot] Tank debuff, deals high ticking damage and then explodes for even more damage and also leaves several pools of [Infested Ground]
[Infested Breath] Targeted cone-shaped Breath. Bait the breath into a wall to save space on [Infested Ground]

--While in the Heart of the Swarm Phase Nythendra will briefly collapse and all [Infested Ground] pools will make their way back to Nythendra. In this phase you can try to roll for better buffs and heal yourself to full HP.

During this the only thing that occurs is [Burst of Corruption].

[Burst of Corruption] - Periodically insects will grow to abnormal size and pulse damage in an 8yd radius every few seconds. Each time you are hit it leaves a debuff that increases subsequent hits by 25%. Just stay clear of them as best you can, but more importantly focus DPS on the boss.


And that is the boss fight, it repeats the entire process until you kill her or she kills you. The enrage timer is 10 minutes and 10 seconds.


As a personal note. Crushing Blows are really punishing, so pray that you don't get Crushed a lot, especially when Volatile Rot is exploding. Also you can't vanish at all on this boss so Mantle of the Master Assassin is not viable. Since we're pushing hard for DPS the next viable legendary is Thraxsi's Tricksy Treads.
Which means Sprint is both a Defensive CD and Offensive CD, how wonderful :)
