While simultaneously battling the joys of updated addons and class changes with the launch of 8.1, Vortex took down Mythrax in his final form.
The fight changes in that Mythrax brings along his pal Xalzaix (Not to be confused with Xalilith), a Squidward-looking fellow who casts some of the same annoying beam abilities for which Mythrax was previously known to have a monopoly. Most of the changes involve stacking to place Xalzaix near the boss for cleaving in P1, and successfully managing Void Echoes in proper raid placement.
Great work, everyone! It's time to kill a slug!
