Heroic ICC25m Valithria Dreamwalker

This time, the portals are red. Also, the clouds do not respawn, so coordination within the portals are important. Heal yourself too, because clouds do damage.
Here are a few more things to note:

Kill order is roughly the same as regular: Skeletons > Suppressors > Mages > Zombies > Abominations.

Cleanse the Gut Spray from tanks, otherwise they will take 50% more damage and get wiped if they are tanking a lot of mobs.

Frostbolt Volley from Skeletons drains 2K mana per cast.

Valithria has a larger health pool and will take more damage, so it is important that healers do not drop stacks!
