Defeating the mirror

I have a Mo/R and am having a lot of trouble beating my mirror. What kind of skills should I equip?

[EDIT] After posting I realized someone else had posted the same question before. I had searched for mirror, but didn't realize that post was right there.

I was also a Mo/R, so here's what I did. Pack a bunch of Nature Rituals that you do not plan on using. Your mirror will waste his time putting them up (5 second casts, so there's a good bit of time wasted). I think I took 5. Then pack smiting prayers to round out your build. Run right up to him while he is throwing up his rituals and blast him with your smiting. I can't recall exactly which spells I used, but Symbol of Wrath, Balthazar's Aura, Bane Signet would be good...

Vai

Thank you. I did what you said and was able to beat him on my first try.
