Nythendra is one of the first bosses in the Emerald Nightmare Raid Instance.

Nythendra was once a member of the Green Dragonflight charged with guarding the world tree, Shaladrassil. When Xavius' corruption of the Nightmare consumed Shaladrassil, it consumed the sleeping guardian as well. Nythendra is now nothing more than a skeletal version of herself, swarming in pestilence, ready to devour anyone or anything foolish enough to enter her lair.



Nythendra is a simple and straightforward alternating two-phase fight, with very few abilities to worry about. Here is a preview of the fight from the Legion Alpha/Beta.



Below is a TL;DR of how to handle Nythendra's abilities, this should be used to familiarize yourself with the boss's abilities, and not as a blueprint for success.



  • Move away from others, towards the edges of the room, while afflicted with Volatile Rot Icon Volatile Rot.


  • In Heroic mode, expect damage to ramp up at the end of Phase One, because of Infested Icon Infested stacking up.
    • In Mythic mode, the stacks no longer reset in Phase Two, resulting in even more damage.
  • Expect damage to ramp up as well at the end of Phase Two, because of the increasing damage of Burst of Corruption Icon Burst of Corruption.


  • Save your cooldowns for Phase Two.


  • When targeted by Rot Icon Rot, place your poison zones next to the edge of the room, preferably in a way that lines are drawn with poison zones from the edge to the boss. You should aim to leave 1/4 of the room free of poison zones, making for an easier Phase Two.
  • In the last beta test, Rot Icon Rot was dealing its damage instantly, making it impossible to stack (especially on Mythic difficulty).
  • Find a spot where there are no Infested Ground Icon Infested Ground poison zones behind you. This way you will not have to move during Phase Two.
  • Do not stand near insects during Heart of the Swarm Icon Heart of the Swarm.
    • In Normal and Heroic modes, it is ok to get hit once or twice.
    • In Mythic mode, damage taken from insects must absolutely be minimised. The encounter is not a DPS race, so it is ok to lose out on damage.
  • When transitioning into Phase Two, find a place to plant, clear of Infested Ground, so that you can focus solely on boss damage or healing before the insects start dealing damage.
  • In Mythic mode, make sure that everyone with over 10 stacks of Infested Icon Infested run into the melee group when Infested Mind Icon Infested Mind is about to be cast. This will make it easy to DPS them down.
