Mistress Sassz'ine, Healer Guide

Patch 7.2.5 Updated
June 27, 2017

Mistress Sassz'ine Dungeon Journal ModelThis page covers a healer-focused strategy for Mistress Sassz'ine in the Tomb of Sargeras. While it's tailored for healers, other roles may also find the information useful. If you have any suggestions or feedback, you can leave a comment below or tweet @PrestonDvorak.

This guide has been updated and maintained based on my own experiences with the fight as well as Dungeon Journal information. I'll continue to update it as-needed.

General Mechanics and Abilities

Normal and Heroic

This is a multi-stage fight with several abilities that are present throughout.

Abilities in all Stages
  • When Hydra Shot is being cast, players must stand in the line from the boss to the targeted player to help mitigate the damage dealt.
    • Being hit applies the Hydra Acid debuff, dealing damage over time, and preventing anyone affected from helping soak for 6-seconds.
  • The tanks will be dealing with Burden of Pain.
    • If the tank with this debuff is taking damage from the boss, it will deal that damage to the entire raid.
  • Sets of three Abyss Stalkers will spawn throughout the fight.
 Stage One - ten thousand fangs
  • Avoid the Slicing Tornado lines that move across the room.
    • On Heroic, there are no gaps between the Torndoes, so they must come in contact with a Concealing Murk to make a gap.
  • Consuming Hunger summons several Razorjaw Waverunner that attach themselves to players, dealing moderate damage over time while using the following abilities.
  • If you have a Razorjaw Waverunner attached to you, stand in the Thundering Shock areas to remove it.
Stage Two - terrors of the deep

During this stage, Sassz'ine summons several large adds to the fight.

  • Ossunet
    • Places Befouling Ink clouds around the room.
      • If touched, these clouds stick to players and deal light damage over time. 
  • Sarukul
    • Appears at the edge of the room and pulls players towards him, dealing moderate group-wide damage.
    • Any players that go within 15-yards of him will be devoured (denoted by a blue circle).
    • Disappears after consuming 3 Befouling Ink clouds on Normal, or 5 Befouling Ink clouds on Heroic.
      • Players with the Befouling Ink debuff should step into the purple circle to "feed" him the ink without taking fatal damage.
  • Vellius
    • Appears at the edge of the room and uses Crashing Wave, dealing heavy damage to players caught in the large line.
Stage Three - vast oceans of wrath

This stage combines spells and adds from the first two stages.

Mythic Differences

  • There will now be Delicious Butterfish around the room for players to pickup.
    • For DPS and Tanks: increases damage done by 2% for each stack.
    • For Healers: increases mana regeneration by 350 mana per second for each stack.
    • Taking any damage causes the fish to fall off and sit on the ground.
      • Any fish on the ground can attract Dread Sharks.
        • Avoid these, they will devour all Butterfish and players within 10-yards.
Stage One - ten thousand fangs
  • Murloc Mash buffs all murlocs for each one not attached to a player.
    • This forces murlocs to be removed in a controlled manner, or requires snares and crowd control.
Stage Three - vast oceans of wrath
  • Murloc Mash is no longer present in this stage as there's no way for players to remove murlocs from themselves.

Healing Strategy

Abilities in all Stages

  • Hydra Shot and the resulting Hydra Acid will deal consistent, moderate damage to affected players throughout the fight.
  • On Heroic, Jaws from the Deep will also deal consistent, moderate damage over time to affected players throughout the fight.

Stage One - ten thousand fangs

  • Players with Razorjaw Waverunner attached to them will need moderate healing over time and should be kept near full health so when they stand in Thundering Shock they don't die.

Stage Two - terrors of the deep

  • Players affected by Befouling Ink will need light healing over time.
  • When Sarukul is present, the group will take moderate damage over time. This may require group-healing cooldowns. 

Stage Three - vast oceans of wrath

  • Players affected by Befouling Ink will need light healing over time.
  • Players with Razorjaw Waverunner attached to them will need moderate healing over time.

Debuffs to Track

  • Hydra Acid causes players to need additional healing over time.
  • Jaws from the Deep also causes players to need additional healing over time.
  • Assuming Razorjaw Waverunners apply a debuff to players they're attached to, this should also be tracked. I'll get the name of the debuff when I remember to check it during the fight.
  • (Optional) Befouling Ink can be tracked because it causes light damage over time. The damage is so light, however, it may not be necessary.

DBM Settings

Below are the DBM settings I'll be using for the Mistress Sassz'ine. You can set them up however you'd like, but these ones should work well as a starting point. Some settings may be Mythic only.

Settings will be added the week Tomb of Sargeras is released.
