This page covers a healer-focused strategy for Fetid Devourer in Uldir. 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

• The tanks will be dealing with Thrashing Terror, with every fourth attack triggering Terrible Thrash on the player closest to the tank. Ideally, this will be the the second tank.
• At 100% energy, avoid the Rotting Regurgitation cone as the boss turns to cast it towards a random player.
• Corruption Corpuscles will periodically spawn in the alcoves around the room.
  • These must be killed before Enticing Essence finishes casting.
    • If the cast completes, the boss will run to the Corpuscle and Consume Corruption, healing and gaining energy.
  • Avoid standing in the stream of waste near these.
• Players affected by Malodorous Miasma will need light healing over time.
  • When this expires, the player is affected by Putrid Paroxysm and will need moderate to heavy healing over time.
  • This effect is applied to random players throughout the fight as well as any players hit by Rotting Regurgitation or the waste stream near Corruption Corpuscles.
• On Heroic, Shockwave Stomp deals moderate damage to the group and knocks players back a large distance.
• At 50% health, Fetid Frenzy increases the bosses' damage dealt and damage taken.

Mythic Differences

• When affected by Malodorous Miasma and Putrid Paroxysm, move away from other players to prevent spreading the effects.
• One of the Corruption Corpuscles will instead be a Mutated Mass.
  • These have more health and cast Enticing Essence more slowly.
