Magmorax

Magmorax was raised by Neltharion from an early age, and his loyalty to him is matched only by his greed. The Lavahydra guards the path to the deepest chambers of the Crucible of Shadows, where its master's secrets are safe from prying eyes.

Heroic Changes
Players soaking puddles now stack a 15s DoT that quickly deals a lot of damage. Reaching 25 stacks of this DoT kills you instantly.
Mythic Changes
The stacking DoT from soaking the puddles is now permanent and persists through death. You can go up to 40 stacks before being incinerated.
When Magmorax casts Molten Spittle, 1 player gets a bomb that needs to be soaked to split the damage and reduce the size of the puddle that spawns from it.
