Mage/Dark Wizard Build for CoW

I need to fight the Corrupter of Worlds for the Temple of Legends quest (as a lvl 68 mage), is there a specific build/strategy I should use?
I have around 11LE (don’t judge i’m poor)

Edit: I am currently Riftwalker

you might be able to do it with this build
try to stay distant and use a meteor - heal spell cycle, while using melee to charge winded. you can use a def pot or something if you have it available

another option if you dont wanna use morph for some reason
