Ranger/Necro need help w/ mirrior image

I have tried everything I can think of and can't win I don't even get a 1/8 off my mirrior image off can somebody help me defeat him with some ideas on this matter and I'm on dialup?

First off, put on some skills like Favorable winds that take a long time to cast so he's stuck with them. Along with that seeing as how you're a necro also, throw in things like blood ritiual that takes off a whole lot of health because of the sacrifice. That should help you quite a bit, with the time to add some extra damage, and the fact that he might just sacrifice himself to near death.

If you take sacrifice spells with you make sure you dont take lifetaps, or he will just tap it back out of ya..and absolutly dont take TU lol
