Mortis Fatal Solo with a mage HD

Was pvp-ing, and Redja asked to record mortis infernal or fatal. There is no way I can do infernal with my stats, but fatal is doable. Unfortunately, recording comes with a lag. I failed to stay in the mortis hitbox so he doesnt deal damage, so had to use some heavy healing with potions) to redja: no rocket science here. kill the dragon in few phases so you have a bunch of potions on the ground for later use when fighting mortis, kill the knights fast, stay in the mortis hitbox when moving around him like recommended by Wigger. But soloing him as a mage is not feasible and even if I ever manage to kill him at infernal, it would not be sustainable and come at a huge price. better farm with a tank in a glass canon mode, much much faster.
