Mo/El - Ascend.. wtf impossible?

How the hell does a Monk be able to beat the mirror.
All I got is a staff.
Tried using some Elementalist skills but that mirror always outdamages me.

I ascended before but that was with a Ranger.

Ive ascended with my Mo/E. I think i refunded all my points into fire magic. And I brought like 3 or 4 skills with me. I used I think it was lightning javelin or something to disrupt, and meteor and fire storm. I entered and he was casting meteor or firestorm right off so I hit him with the lightning disrupt skill and knocked him down. Then I hit him with meteor which knocked him down again and then I hit him wiht firestorm. Then I hit the lightning disrupt skill again and one more fire spell and the whole thing lasted like 10 seconds. Its easy you just have to find the right skills to use.

I did this on my first try. Put your fire skills up to 12 or so, and only bring orison for healing. Use aoe's and just outdamage him. Eventually he'll try to heal, but you just keep doing damage.

Bring lot of weak enchantmen that wont help him and like 1 or 2 damaging skills.. don't bring heal.
you can finish him up while he waste his time casting enchantment that wont help him at all.

Thank you all for the nice replies.
