Maw of Souls Mythic+ Guide

Instance Breakdown

Recommended Comp for high keys: Bring at least one or two low cooldown interrupts to make the Champions and Mistmenders easier. Your composition for Maw of Souls is otherwise pretty flexible. Melee get chewed on by some of the trash packs but you’ll bring them anyway for the interrupts.
Instance Timer: 24:00
Average # Mobs per pack: 2.8

  • Ymiron, the Fallen King

    Ymiron, tank murderer 

      Maw of Souls: Ymiron

    Dungeon Journal+

    Dark Slash   Single Target   Shadow   

    Screams of the Dead   AoE   Debuff (Fear, Magic)   Shadow   ✔Dodgeable

    Winds of Northrend   AoE   Frost   ✔Avoidance

    Bane   Ground Effect   Shadow   ✔Dodgeable

    Arise, Fallen   Summon Effect


    You should know

    • When Arise, Fallen is cast, you’ll get one skeleton for every Bane globule still active. This means you can greatly reduce or even remove the skeletons by soaking these before the cast. They do deal very heavy damage so you’ll need an immunity like Divine Shield or Aspect of the Turtle to remove them efficiently. This is amazing on Necrotic weeks.
    • Dark Slash is Shadow damage so you’ll want to use anti-magic defensive cooldowns to reduce its impact. Anti-magic shell, Spell Reflect and Empower Wards are all very effective as is anything that gives you more health. Don’t be afraid to reach out to your healer for an external cooldown if necessary. You can expect a Dark Slash every 30-45 seconds and it really hurts.
    • The Skeleton adds cannot be slowed, stunned or knocked back so your tank will have to rely on personal mobility cooldowns to keep incoming damage low.
    • You can get a pet to taunt (or a Moonkin to drop Force of Nature treants) a second before the Dark Slash and they’ll absorb the hit entirely.
  • Harbaron

    What makes his scythe ‘cosmic’ anyway?

    Maw of Souls: Harbaron

    Dungeon Journal+

    Cosmic Scythe   AoE   Arcane   ✔Dodgeable

    Nether Rip   Ground   Shadow   ✔Dodgeable

    Fragment   Summon Effect   Debuff (stun)   Shadow

    Void Snap (Shackled Servitor)   AoE   Shadow   ✔Avoidance   ✔Interruptable


    You should know

    • Nether Rip spawns under random players which means it’s controllable. You won’t really run out of room since it only lasts 30 seconds but avoid cutting off any escape paths or dropping it under the boss if possible.
    • Fragment targets take very heavy damage and are stunned for a short time. Stack up near the boss so that the boss can be cleaved while you burn down the fragment adds. The fragment adds can be stunned and knocked back.
    • Void Snap will ruin your life. It’s a long cast and needs to be interrupted 100% of the time.
    • Cosmic Scythe is a little larger than the animation, just take a few steps back from the boss when he’s casting it. It also hits behind the boss, so don’t think you’re safe there.
  • Helya

    Is it weird that her tentacles hit harder than she does?

    Maw of Souls: Helya

    Dungeon Journal+

    Phase 1

    Rapid Rupture (Destructor Tentacle)  Single Target   Physical   Debuff (DoT)   

    Piercing Tentacle   AoE (6 yards)   Nature   ✔Dodgeable

    Taint of the Sea   AoE   Nature   Debuff (Magic, DoT)   ✔Dispellable

    Turbulent Waters   Ground   Frost   ✔Dodgeable

    Brackwater Barrage   AoE   Frost   ✔Dodgeable

    Phase 2

    Corrupted Below   AoE   Shadow   ✔Dodgeable

    Torrent   AoE   Frost   ✔Interruptable


    You should know

    • The tank will need huge amounts of healing when contesting the Destructor Tentacles. They stack an awful bleed (Rapid Rupture) that’ll require healing even after the tentacle is dead. It’s ok to go into phase 2 with no tank / healing cooldowns so use all of them. The bleed can be removed with Blessing of Protection and if you have access to one you should use it.
    • DPS need to focus Destructors whenever they’re up (Dotting / cleaving the Grasping Tentacles is a good idea).
    • It’s ok to move out of melee range of the destructors if the tank needs to dodge the Brackwater Barrage. You can take 1-2 Smash without too much danger to your party, just make sure nobody else is in melee range.
    • Helya will submerge every ~90 seconds during phase 2 and you’ll need to kill her within two phases most of the time to hit the timer. She stays submerged for about 20 seconds.
    • You can heroism / bloodlust in either phase but I’d recommend doing so in phase 1 if you don’t trust your tank to stay alive and in phase 2 if you want to maximise DPS or will get an extra submerge if you don’t.
