Playstyle
Fetid Devourer deals entirely Physical damage, almost entirely from melees (or Terrible Thrash Terrible Thrash).
There is no forced tank swap on this fight. This encounter does require two tanks due to Terrible Thrash — every fourth melee, the boss will attack the nearest person to the tank for 300% of a normal melee. The two tanks must be on top of each other at all times. Earthwarden does not work against Terrible Thrash.
When the Corruption Corpuscles spawn, it may be optimal to drag the boss to one of them to maximize cleave. Otherwise, tank the boss in the center of the room to minimize travel time.
Catweavable: No
Mythic
It is recommended that the boss be dragged on top of the Mutated Mass for maximum DPS.
Tips and Tricks
Use Stampeding Roar during Rotting Regurgitation to help the raid manage their movement, or when Corruption Corpuscles spawn.
You can use Skull Bash or Wild Charge during Shockwave Stomp to quickly return to the boss, although keep your co-tank’s movement options in mind as well; if they are not able to keep up with you, it’s better to get knocked back with them.
Tanking Terrible Thrash
While guardians are more suited to the main tank role due to gaining resources from being melee’d and their high uptime active mitigation, it is completely viable to have Guardian tank the Terrible Thrash mechanic.
If you are the designated off tank, you will be taking a Terrible Thrash every 6 seconds. You must be topped off before each one, and have at a bare minimum 1 stack of Ironfur (ideally 2 or more). To be extra safe, you should cover any Thrashes where you only have 1 stack with Barkskin or an external cooldown, and if you can’t have Ironfur up for a Thrash use Survival Instincts.
To get the most out of Bristling Fur, you should use it right before Terrible Thrash so that it covers two casts. Bristling Fur will cap your Rage both times you get hit, which will help you maintain your 2 stacks of Ironfur.
Be aware of Fetid’s spell queueing as well; Terrible Thrash is one of the lowest priority spells, meaning he can (and will) cast any of his other abilities before Terrible Thrash even though the timers indicate Terrible Thrash is coming next. If you can, try and avoid spending Rage/using cooldowns until he actually starts the Terrible Thrash cast.
Use the downtime during the Consume Corruption cast to catch up on Rage generation.
