Elemental Boss Guides – Icecrown Citadel – Lord Marrowgar Heroic

April 22, 2010 2 comments

This guide (and all following heroic or hard mode encounter guides) will assume that you are familiar with the fight on the normal level of difficulty. You can read my tactics for this encounter here.

Lord Marrowgar gains a significant increase in health on heroic mode:-

  • 10 Man Normal – 6,972,500 health
  • 10 Man Heroic – 10,500,000

Aside from the obvious differences in health pools, Lord Marrowgar’s abilities also deal more damage:-

  • 10 Man Normal – Coldflame – Deals 6,000 Frost Damage per Second for Three Seconds
  • 10 Man Heroic – Coldflame – Deals 8,000 Frost Damage per Second for Eight Seconds

His bonestorm ability now causes additional damage over time in the form of a bleed effect.

Phase One

We use identical positioning to the normal mode encounter.

It is vital that everyone stacks under Marrowgar. This allows for very fast removal of players from the bone spikes without your melee needing to run around the room. When correctly positioned like this, the coldflame will cause no problems in this phase of the fight. One thing to note, particularly when you begin to regroup after a bonestorm phase. As you’re in melee range it’s vital that you do not stand infront of Lord Marrowgar, his saber lash ability hurts. If marking the tanks ensures that your DPS always find the back of Lord Marrowgar then do so to avoid unnecessary DPS or healer deaths.

We use heroism as soon as every is in position and burn as much as we can in this first phase. The priority for all DPS should remain the bone spikes.

Phase Two

Due to the significantly increased damage of Bone Storm in heroic mode, it’s vital that your raid move away from Marrowgar just before phase two begins. All the boss mods provide timers for the incoming Bone Storm phase. He also emotes just before the transition with:-

  • Lord Marrowgar creates a whirling storm of bone!

Aside from the increase in damage dealt by Bone Storm and Cold Flame in this phase, there is one primarily difference between heroic and normal modes of the encounter. Throughout phase two on heroic mode, player will still be impaled by the Bone Spikes. As healing will be pushed due to the increase in damage from other sources, it’s vital that the DPS burn these spikes down fast.

Positioning in Phase Two

We make one slight difference to the positioning in the second phase of this encounter from the normal mode. Due to the increased damage taken by the entire raid, healing becomes very pressed. We have a lot of problems in our early tries with people running out of range of healers and thus dying.

In the centre of Lord Marrowgar’s room is a circle pattern on the ground. We stay within this during phase two. This ensures two things. Firstly, the bone spikes don’t occur on people so far away that the DPS have no chance of hitting them before the impaled person dies. Secondly, no one should be out of range of your healers. (For reference, we use three healers on this encounter.)

You will still get coldflame in phase two. Your melee DPS can’t always be expected to reach the bone spike due to flames and because of this, it is essential that your ranged DPS are fast and bringing down the spikes.

As with the normal mode, phase one and two alternate until Lord Marrowgar is dead.


As with the normal version of this encounter, no specific totems are required. For elemental shamans that are free to use fire DPS totems, the advantage of this positioning is that you don’t have to worry about range to the boss.


There is a lot of incoming raid damage on the heroic version of this encounter and it’s vital that you’re aware of this, even as a DPS. If you’re used to being able to continue DPS despite the bone storm on the normal version, be ready to move on the heroic version as it does a lot more damage. As an elemental shaman, your primary concerns during this encounter are:-

  • Being correctly positioned during phase one
  • Switch DPS to the bone spikes as soon as they appear in both phases
  • Avoid the bone storm during phase two
  • Avoid the cold flames. During phase one, these shouldn’t be much of a problem due to the positioning. In phase two, you’ll find them a much larger problem, particularly as you also need to be in range of the spikes to DPS them

At the time of writing, Decimation have just two more heroic modes left in Icecrown Citadel; Sindragosa and the Lich King. Never the less, this is still the hard mode that causes us the most stress (and annoyance) on a weekly basis. Be aware that while the mechanics barely change, the increase in raid wide damage is considerable and as a DPS, you should be doing as much as possible to avoid excess damage to ease the healer stress.
