Summary
(A fairly long and complicated encounter. 2 tanks 3 healers for 10 man.)
Phase1: 100% - 70%
.Infest does damage to the entire raid, and gets dispelled when players are above 90% hp. Pre-shielding players helps.
.Shambling Horrors (the big adds) do a frontal cone attack,have an enrage that can and should be tranquilized. The enraged shockewave is dangerous, either dispel the enrage or stun the add when it casts it.
.Dispel Necrotic Plague on the players. On dispel it will jump to another player or to an Add, dispel it until it jumps to the adds. It will then kill the adds. The plague jumps to the nearest unit on dispel. Preferably you would use it to kill the Shambling Horror. (bid add).
.Stop dps on lich and kill the Horror before transition.
Transition phase:
.Spread out and run towards the outer edge of the platform.
.Ranged dps the frost orbs headed towards the raid. They have an easy to see white’ish beam.
.A Raging Spirit will appear above a random player every 20 secs, dps them down, they melee hard.
.Spread out to avoid extra damage from Pain and Suffering.
.Lasts for around 1 minute.
.At the end of the transition the outer edge of the platform will fall off.
Phase 2: 70% - 40%
.No more Ghouls or Horrors, instead a Val’kyr will try to drag a raid member off the edge. Just stay close to the middle and dps it down fast. They can be stunned and slowed.
.Stay out of the dark pool. It grows when it hits a player.
.Soul Reaper does 50k(60k on 25 man) damage on the tank 5 secs after being applied. The offtank has 5 secs to taunt , the main tank can use those 5 secs to pop some cooldowns. Soul Reaper is casted every 30 secs, so manage your cooldowns properly, with each tank taking the hit and using a cooldown every minute.
.Again watch the cooldown on the val’kyr, you don’t want one up as you go into transition.
Phase 3: 40% - 10%
.Run away from the Vile Spirits that explode upon reaching a player.
.Harvest Soul does 40k on 10man , 90k on 25 man on the targeted player. Use a damage reduction cooldown on that player. Then that player will be inside Frostmourne where he will have to help Terenas kill Spirit Warden. They can help him either by dps-ing the Spirit or by healing Terenas.
.Players have 1 minute to kill the Spirit Warden.
Phase 4: 10% - 0%
.The Lich King kills all. But do not release, this is intended.
.Terenas will resurrect all the players, and will hold the Lich “stunned”. Dps him down.
