ICC25HM: Lord Marrowgar

This is the first in a series of guides to the bosses of Icecrown Citadel 25man Heroic Mode. I’ll be adding more of these as time goes on and as we down new bosses.

So, what’s different?

• Bonestorm will probably kill anyone in the epicenter
• Coldflame does more damage, stays up much longer
• Bone spikes occur during Bonestorm

Group composition we used: 2 tanks, 6 healers, 17 DPS.

The trickiest part of this fight is going to be the Bonestorm. You’d think Marrowgar would hit harder on the tanks but, honestly, he doesn’t. He was hitting me for an average of 26k last week, which on a tank pushing 70k hp is a tickle. I’m very comfortable two tanking this fight and freeing up one dps, rather than splitting the Sabre Lash three ways.

Coldflame turns into a fun game of hop-skotch. You and your partner tanks will be spending any non-Bonestorm moment of the fight strafing left or right. Likewise, I usually mark myself and the other tank, and then (because such is privilege of MTing) I call out in vent which way I’m going during each burst of Coldflame. Usually left four times, then right, rinse, repeat, etc.

To make it easier on the rest of the raid, they can just hide in the red circle under Marrowgar. Coldflame trails form just outside it. Tanks could theoretically do this too, but with only the two of us I’m worried about the tight confines of the inner hitbox leading to accidental Sabre Lashings. Plus, strafing is much more fun.

So, like I said: Bonestorm hurts. But, thankfully, it’s easily mitigated by a strategy posted by Rilgon on Stabilized Effort Scope. There is a cast time when Bonestorm is about to happen, so as soon as I see him casting it, I split one way, my co-tank splits the other. We spread to opposite ends of the room along the base of the ice. Likewise, a pre-appointed Hunter goes to one side of the door, and a Boomkin heads to the other. Four points to a square. Everyone else clumps in the middle.

The reason four of us spread out is Marrowgar will generally target the person farthest away from him to park a Bonestorm on top of. If it’s a tank, great; if it’s the boomkin, he can Barkskin; if the hunter, he can use Deterrence.

Ranged need to kill spikes that pop up in Bonestorm ASAP. Coldflame likes to worm its way under those people. If the Hunter or Boomkin that eat Bonestorms get spiked, I throw a Hand of Sacrifice on them to be safe.

If Marrowgar jumps into the middle, I pop Divine Sacrifice (the whole thing, not just Divine Guardian) and soak up some of that damage. Putting your healers in a group with you isn’t a terrible idea to give them some breathing room in those “oh crap” moments.

Honestly, this fight is a cakewalk and you’ll probably one shot it on your first attempt like we did. The hardest part for your raid will be scattering out of the middle of the Bonestorm if Marrowgar dives into the quivering pile your raiders are surely forming.

The lewt!
