Mirror Self

I've passed all of the trials for ascension and only have to face my mirror self in the mesa. My only problem is that my mirror self's casting time seems to be about half what mine is, and she does much more damage with her spells. Any advice for a necro trying to defeat her mirror self?

I wish I'd had a harder time with my W/E to give ya better input, but here is what you might want to do.

Equip one or two spells that you need and make your other spells things that you don't have much attributes in and go in again. It is possible to defeat your "self" but with some it takes time and patience. Go in there and knock your image around with whatever weapon you are carrying and find your niche.

I don't know if that helped much but I hope it made sense. Good luck and happy thrashing.
