As always, remember, these aren't in-depth guides for your heroic raid. They're arming you with just enough knowledge to get your group through the LFR version of the fight, mostly intact.
- Healers, in phase 1, your heals won't heal. Instead there will be colored blobs on the raid frames. Keep them green. They're absorb shields, that you're building by healing.
- He'll do cone-shaped smashes that affect segments of the room. Don't stand in them. Also, after every three smashes, he'll re-explode the three areas he smashed. Don't stand in that.
- Soak purple swirls
- When he goes into Blood Rage, stack up. Run out with the debuff if your healers are struggling.
- Everything hurts more as the fight progresses.
