The release of Midnight pre-patch brought some new tameable pets for hunters, and one of those is an iconic raid boss from Dragonflight. The sixth boss of the Aberrus, the Shadowed Crucible raid, Magmorax, is now available to be tamed.
Magmorax is a hydra, making it a tenacity pet. It’s a great option for players when lust isn’t needed, giving you 
Fortitude of the Bear and 
Endurance Training.
How to Tame Him
Getting your hands on it is very simple. You just have to clear the first six bosses of the raid! You only have to do the raid on normal difficulty, which is very doable.
Rashok may give some difficulty with his tank mechanic for hunters that aren’t geared, but the rest of the bosses should offer very little resistance.
Once you clear Zskarn, jump down to Magmorax’s platform and clear the adds. He’ll jump out of the lava and you can tame him. He’ll respawn shortly after, allowing you to tame him again for a second time.
