Icecrown Citadel 10m: Heroic Lord Marrowgar: Overview/Phase One

ICC Lord Marrowgar SQ

The Heroic mode for Lord Marrowgar is fairly straight forward and the general setup of the raid goes mostly unchanged. In this guide I will only cover what is important and anything else you should honestly know if you're doing Heroic modes. Depending on the class, gear, and players' abilities you'll want 2-3 healers, 2 tanks, and the rest dps. As for the positioning, have your raid stand at the back of Lord Marrowgar just inside the red circle that appears when he is selected. If you have a hunter, they will need a bit more range and should stand to the side so they are easily visable to the raid and range can switch to their Bone Spike easier and faster. Standing inside the red ring will also cause the tanks to see more flames than usual and they should cordinate which direction to strafe in and move in sync.

  • This is one of the easier Heroic modes and the main changes are increased health pool for Marrowgar, increased damage from Bone Storm damage and other abilities, and Bone Spikes during the Bone Storm phase.
  • Phase one is extremely simple and dps just needs to focus on breaking out Bone Spiked targets as quickly as possible and burning down the boss as much as they can.

Icecrown Citadel 10m: Lord Marrowgar: Phase Two & Recap

  • When phase two or the whirlwind Bone Storm phase is about to transition, healers need to be HoT'ing up the raid, throwing out shields if possible, and topping off the tanks. If you have a hunter, Marrowgar will head for them first giving the rest of the raid a chance to flee but, don't scatter like crazy. The raid needs to stay relatively close together or you will get a random person spiked in BFE with noone to save or heal them. AoE healing can be very effective here. Travel somewhat in a group away from Marrowgar's whirlwind until the phase transitions back to phase one.
  • At around 20% and just after transitioning back into phase one, pop Blood Lust or Heroism and nuke Lord Marrowgar.
  • Just to simplify and recap heroic key points.
  • Phase One:
    Raid stack on Marrowgar's back.
    Tanks strafe in sync out of cold flames.
    Around 20% pop BL or Heroism

    Phase One to Two Transition:
    Pre-HoT raid and top off tanks

    Phase Two:
    Stay away from the Whirlwinding Bone Storm
    Stay semi-grouped up and AoE heal
    Immediately kill Bone Spikes

    Phase Two Back to One Transition:
    Tanks must pick up together
    Good time to pop tank cds
    Helps to have a Hunter MD
    and most importantly, have fun!
