Playing fire mage on General Vezax HM encounter

Hey guys

I'm looking for some pointers on playing fire mage on general Vezax encounter and how to not run out of mana fast?


Thanks

if you can i would highly recommend you going arcane on vezax, it is insanely strong. 2xarcane blast ->arcane missle and repeat. I've tried fire once on that fight, but since you cant regen, i would not recommend fire.
