This fight is the first boss encounter in Icecrown Citidel and is pretty easy if executed right. Basically your going to want to run in and have the tanks turn him around faced away from the raid and stack on top of each other, the damage the boss does will be dispersed between them. Tank healing on this fight is where most of the heals will be going so be ready for that and Trees make sure you keep a couple hots on the tank at all times.

Next thing will be the bone spikes, they are pretty easy to deal with you will only get 1 spike in 10 man and you will get 3 spikes in 25 man. You will not need to deal with these immediatly, if a fire spawns under someone who is spiked... Lets just say it won't be very fun healing through that. So all dps switches to the spikes when they happen. A good macro that all dps should have is /tar Bone Spike

During the bone storm phase you are going to want to make sure you place your healers throughout the room. while his bone storm doesn't do too much damage a dps could easily die if they are on the oposite side of the room as a healer.

In the Heroic mode of this encounter he of course has all his same abilities, however he now hits a lot harder. In our group we decided to stack all dps and healers in melee range, then have the tanks dodge the fires with a 3 point movement rotation. This works well and I would suggest it for your raid for sure.

The first difference I would like to point out is with the Coldflame. I did not notice him using any more then usual however you will notice that it lasts a hell of a lot longer and will be everywhere as well as of course it will do more damage.

The Bone Spike Graveyard does the same amount of damage as in every other version of this fight, 9,000 initial damage and 10% of health for every second its up. The problem with this in the heroic version however is that he doesn't stop casting bone spikes just because he's in Bone Storm, and yes you will take damage from bone storm while your spiked. Unlike in the normal mode the bone storm damage is not insignificant, it really hurts. He will also do 1 extra charge at someone in the Heroic version of the fight.

The execution of this fight has to be tight until we have the gear (or they put the added damage and healing buff for ICC) to blow through this. The way we did it was we spread out around the small circle in the middle of the room about 5 seconds before bone storm happened and our lovely priest Oopo put shields on everyone. If anyone does not spread out early then their bubbles will break early, and thus not be very helpful. We all stay within this general area so that all healers can help heal all raid members and if one gets Bone Spiked then the others can pick up the slack while they are broken out. You can not spread out too far because if your not in range of at least 2 healers you will more then likely die.

The one piece of advice that I would give everyone above all else is to concentrate on execution during the bone storm phase. If you execute everything right its not that hard to keep the raid up but if you have anyone who doesn't know what their doing the healers won't be able to help them
