The Dragons of Nightmare make up the fifth boss in the Emerald Nightmare Raid Instance.

The Emerald Dream was entrusted to Ysera for safekeeping, and the mightiest of her green dragon brood were assigned to stand watch over four portals that connected directly to Azeroth. But even before the Cataclysm, these dragons began to show signs of corruption. Now, the path to the Nightmare's core runs through the dragons' lair.



The fight against the Dragons of Nightmare can seem daunting at first, because there are 4 dragons (Ysondre, Emeriss, Lethon, and Taerar), which have a shared health pool and several abilities (some shared, some not shared).

In reality, things are much simpler, because the raid only ever faces 2 dragons at a time, one of them being always Ysondre. Moreover, the raid needs to be split in two groups, each facing a single dragon. So most raid members are dealing with one Dragon at a time.

Here is a preview of the fight from the Legion Alpha/Beta.





  • Swap dragon with the other tank at 7 stacks of the Mark.
  • Do not get Corrupted Breath Icon Corrupted Breath cast at the raid.
  • Pickup adds, except Dread Horrors (unless many spawn).


  • Dispel everything! (root from Call Defiled Spirit Icon Call Defiled Spirit, sleep from Seeping Fog Icon Seeping Fog, and Shadow Burst Icon Shadow Burst in Heroic mode).
  • Save healing cooldowns for where the raid messes up and spawn extra adds or takes extra damage.


  • DPS the bosses and any add that spawns, especially spirits from Siphon Spirit Icon Siphon Spirit, which cannot be allowed to reach Lethon.
  • Interrupt the casts of Corruption Icon Corruption from Essences of Corruption.
  • Stand on top of the flower from Nightmare Blast Icon Nightmare Blast if no one else is, in order to prevent Dread Horrors from spawning.


Move away from all the ground effects. The only one that cannot be avoided is Call Defiled Spirit Icon Call Defiled Spirit.

In Mythic mode, the fight feels the same as in Heroic mode, except for players entering portals to deal with the Lumbering Mindgorger.


Mythic-only: Lumbering Mindgorger

Make a small team of DPS players and 1 healer to deal with the Lumbering Mindgorger. They need to have good burst DPS and a short-cooldown interrupt.
