Valithria Dreamwalker Boss Strategy Guide

This battle is a very heal-intensive fight. Healers must heal Valithria in addition to their own raid members. Start by splitting your raid into three groups. Two of the groups should include your heavy-hitting DPS, with one ranged tank in each of the two groups. They must focus on keeping the adds from getting past them and hitting the third group, which is comprised of your healers.
Have all your healers focus on healing Valithria at first, but you should assign two to pick up raid members as the fight goes on. The amount of damage the raid takes will increase as the battle drags on.
DPS focuses on simply taking the adds down as quickly as possible.
Healers must run into the green portals as often as they are available. Once inside the portal, the healer then floats through the air and collects as many green clouds as possible. These clouds give the healers a valuable buff that regenerates mana and makes their healing more effective.
The two ranged tanks should focus on kiting the Blistering Zombies away from the rest of the raid. When the Blistering Zombies are about to explode, run away if you want to live. The two main tanks should focus on keeping aggro off the rest of the raid, especially the healers. Main tanks should pick up any ads, especially the Risen Archmages and the Glutonous Abominations.
Stay out of the blue portal-like areas that are cast by the Archmages. These do a lot of damage and might kill you.
