Adds

• Ghostly Priest  - casts Shadow Word: Pain, Circle of Destruction, Cower in Fear and Dark Mending.
• Phantom Mage  - casts Fireball, Frostbolt, Chains of Ice and Flamestrike. Summons Phantom Hallucinations.
  • Phantom Hallucination - same spells as the Phantom Mage. Summoned with the same amount of health. Explodes when killed.

• Spectral Footman - Warrior who can shield bash and enrage.

There'll be 5 waves of adds at first, each wave with more numbers than the last.   Falric becomes active at the 5th wave.   The adds will be proximity aggro'd at first, so tank takes point, kill their healers.

When Falric is active, there's the whole fears and stuff to dispel.   Hopelessness is a debuff that occurs as his health drops, so try not to die as it'll be harder to kill.

After Falric dies, prepare for Marwyn...

• Shared Suffering - Deals 16000 Shadow damage over 12 sec to an enemy target. When removed, it splits the remaining damage to the target and his allies. Instant. Magic debuff. 4,000/3 sec on normal. 10,000/3 sec on Heroic

Adds - Same as Falric

Marwyn's set of adds start spawning when Falric dies, it's a 10 wave gauntlet.   Marwyn will be active at the 10th.   Same type of adds, deal with them again.

First trick is more void zones, stay out of the wells.

Second trick is the Shared Suffering, you might not want to mindlessly cleanse that.    Perfectly healable anyways.   Cleanse it nearer to the end if you want.

The Lich King

• Remorseless Winter - Slows movement speed by 75%. Debuff on the Lich King for the duration of the encounter.
• Remorseless Winter - Deals 7069 to 7931 Frost damage every 1 sec. Cast on players within 10 yards of the Lich King.
• Fury of the Frostmourne - Deals 1,000,000 Shadow damage to all enemies. 2.6 sec cast. Only used if the players fail to escape and the Lich King catches up with them.
• Summon Ice Wall 50,000 yd range — Instant
• Summon Raging Ghoul 10 yd range — Instant - leaps at their targets
• Summon Lumbering Abomination 10 yd range — Instant - Cleave their targets and also spray vomit on their targets.
• Summon Risen Witch Doctor 18 yd range — 1 sec cast - cast Shadow Bolt, Shadow Bolt Volley and Curse of Doom

The goal of this is to escape the Lich King.   If he catches up, you're fucked.

Basically keep moving down the tunnel, Lich King will summon Ice Walls, and you'll have to kill all the adds that appear with that.   Do it fast and keep moving down as soon as the walls open up.
