Positioning

Since Drest’agath is stationary, your tank should just face her away, and everyone should be spread around the room. Move to the adds you need to kill as they spawn.

Strategy

  • You start out fighting Drest’agath and two Eyes of Drest’agath
  • Tanks need to be on Drest’agath the entire fight. The adds don’t require a tank
    • Tanks will swap when Volatile Seed is applied
    • When you get seed, move to the adds, preferably a Tentacle if possible
  • Players afflicted with Mutterings of Insanity need to move towards the edge of the room
    • Everyone else needs to make sure they aren’t in the giant swirlie
  • Damage should be focused on the adds, as anything you do to the boss will just be healed up
  • Healers should use a raid CD every time the boss casts Throes of Agony
  • Make sure to get out of the purple graphic for Entropic Crash
  • Make sure to dodge Void Glare, both from the boss AND any Eye adds which are alive
  • The tank afflicted with Volatile Seed should try and have it explode on as many of the adds as possible
  • In general, you want melee DPS to nuke the Tentacle, and ranged DPS to nuke the Maw
    • You’ll need 1-2 healers to be within the cloud for the Tentacle to keep the melee DPS alive
    • Once the Tentacle or Maw dies, those DPS players then move to any remaining Eyes
  • About 25 seconds into the fight, you’ll have 3 adds spawn. One Eye, one Tentacle, one Maw
    • Try to hold off killing the initial 2 Eyes you start with. You want to kill the 2 Eyes and 1-2 of the newly spawned adds around the same time
      • Each add you kill drops 5 puddles of Ichor, and they last 25 seconds
      • Once you kill enough adds that every DPS player can get an Ichor , everyone should run over a puddle to get their Ichor debuff
      • Follow this up with Bloodlust, and a hard nuke phase on the boss
    • Ignore any remaining adds until the Ichor debuffs drop, then swap and kill them
  • From that point on, kill adds as they spawn. Make sure all Ichor puddles get soaked. 
    • Prioritize letting DPS who have their cooldowns available to soak puddles
    • Soaking puddles, and then letting people with Ichor nuke the boss, is priority
    • Whenever you don’t have Ichor, work on killing off add
