This is the only boss in The Dreamrift and is a step up from the bosses in The Voidspire.  This is a fight that involves two "realms".

Phase 1:

• Adds will spawn in the second realm.  In order to reach them, some need to stand in the tank soak (yellow circle).  Alternate soak groups.

• Killing the adds in the second realm forces them into normal realm and start walking towards the boss.  Kill them (again) before they reach the boss and before boss reaches full energy.

Phase 2:

• boss flies up and does lines of breath that leaves fire and adds.  Avoid breath and fire, interrupt, group up and kill adds before end of the phase.
