Things to watch out per role (25 man)

MT
- Tank the red dude in the dead center of the room.
- Call out purges when you see the 10 buffs asap or its gonna hurt.

OT(s)
- Be ready for the Mistress of Pain, its a hard to miss portal (very similar to the one that happens on one of the Ogri'la dailies)
- The Infernal Volcano shoots 3 black/greenish balls in the air, where they land, the Infernal will land.
- The Infernals charge random raid members and then stand there chanelling an AoE. Taunting wont do a damn thing. I don't advise moving to the charge location.
- It is possible to get targeted by Fel Legion. Move away from anyone's path when/if you get it.

Melee DPS
- You will be dpsing the boss all the time during this fight.
- You can (and will) be targeted with Fel Legion. This means you have to run away asap or you'll burn the other melee.
- You can be targeted by the Infernal's charge. At that point I would advice for all melee to move away from the boss to avoid the AoE damage until you can get visual confirmation that an interrupt has occured.
- ^ If you can interrupt the Infernal, do so.

Ranged DPS
- You will be changing targets between boss, Mistress of Pain and Infernal.
- Spread out in a circle around the boss.
- Move away from the Infernal's charge AoE and interrupt from range if possible.
- Count to 3 or 4 and then move away on Fel Legion. (n)

Healers
- If you are healing the OT(s), try and follow them.
- Move away from the Infernal's charge AoE and interrupt from range if possible.
- Move away on Fel Legion.


Make sure you DON'T run away when you have Incenerate Flesh. Green fire at your feet = run, weird red/black fire on your body = stay put.

and when he dies...make sure you heal anyone that still has the Incenerate Flesh debuff. lol

Like the way you have this posted in point format

Keeps it very simple rather than reading paragraph after paragraph and getting confused where there is a lot going on in this fight

I snagged this from TankSpot. The only modification I made was for Ranged with the Green Fire, wait a few seconds before you run to the wall so there is less green crap all over.

In 10-man, if you're at full health, you can count to 6 before moving.

+1 for the format, thanks for the info

Updated post to remind people not to run away when they have Incinerate.

Much more detailed strategy guide that involves Melee going after the adds as well.
