Blackwater Behemoth

Updated on 11/21/2020, 10:18:23
Summoned from depths unknown, the Blackwater Behemoth lurks in an abyss so dark that not even the naga dare to venture into it. Only Azshara is capable of taming the beast, and she has trained it to faithfully guard her treasures.

    Fight Summary

    Before the encounter begins, interact with the Oxygen-Rich Membrane either at the start of the trash towards the boss or nearby the boss platform, this will give you additional swim speed and allow you to breathe underwater.

    When you are underwater you will have the Darkest Depths debuff which will reduce the healing you receive by 100%. To be healed again you will either need to get the Bioluminescence buff or Radiant Biomass.

    On each boss platform there are two Shimmerskin Pufferfish, and when killed it will spawn a large Bioluminescent Cloud. Moving into this cloud will give you the Bioluminesence buff.

    Touching any Jellyfish whilst swimming will apply a 8 second DoT.

    [Heroic] Touching a Jellyfish will apply Bioluminesence to you. Avoid the Jellyfish whilst swimming across.

    Platform 2

    When you arrive here the boss will still be channeling Cavitation. If this cast finishes it will deal heavy raid damage every 2 seconds. However you are able to deal full damage to the boss during this period, and pre-collect Bioluminesence from a pufferfish.

    The rest of the mechanics are the same as Platform 1, however there is an open gap between the two ranged platforms and the melee platform.

    When the boss reaches 100 energy it will move to the final platform.

    Platform 3

    The boss has no energy on this platform and the raid only has the two pufferfish to use. This is the soft enrage of the encounter.

    There are more gaps in the platform and the overall space for the raid is smaller.

    Mythic

    Piercing Barb - The boss will target a ranged player and cast a beam on them. The damage from the beam is split with all players inside of it, however the clump detection is still active so you want to spread out along the beam.

    Tanking Notes

    Class Tips/Tricks

    Vengeance Demon Hunter
