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".  Adds will spawn in the shadow realm with shields on them, moving towards the boss.  Don't let them get to the boss!

Phase 1:

• Bloodlust on pull.

• (HEROIC: split raid into two groups)

• Pull boss to the edge of the platform.

• Adds will spawn in the second realm.  In order to reach them, 5 players/a group need to stand in the tank soak (yellow circle).  (Alternate soak groups on Heroic).

• In shadow realm, tank collects all adds away from the boss and everyone nukes down their shields.

• Breaking their shields sends them into normal realm and start walking towards the boss, and leaves puddles on the floor - avoid.

• Those in normal realm kill them before they reach the boss and before boss reaches full energy.

• Interrupt Haunting Essence, tank and focus Colossal Horror.

• Consuming Miasma debuff - blue circles - this gets rid of yellow puddles when dispelled.  Use mitigation/heals to clear puddles.

• TANKS have boss face away from the raid for Rending Tear.

• When the boss gets to 100 energy, it casts Consume and eats any adds left up.  Knockback.  Then ..

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.

• After three breath drive-bys, boss smashes back down, doing huge damage, knocking everyone up and consuming any remaining adds.  Make sure all adds are dead before this!  Then back to P1 - drag to edge of platform again.
