How can N/Mo kill Dopelganger ?

My character is Necromancer/Monk 18 lvl.I have finished 3 missions in desert. So, now I need to kill Dopelganger fo getting accsess to next missions. My current location Augury Rock. I have tried to do that lots of time without success It has killed me during 10 seconds and use my spells against me. Please help me with skill combinations. My character has tormentor armor. I have got onlu 2 elite skills

the dopelganger isn't very hard...it'd probably benefit you for later missions to think of a skill set that can beat it. But to give you a hint...basically load up on skills that have long casting times but do pretty much nothing. Also bring healing breeze as your only heal, if it hasnt been changed your dopelganger won't use healing breeze.

use health scraficing spells...start off with awaken the blood....

health sacrificing, healing breeze (he won't use), useless enchantments (so he lose this degen and could only use it once while gaining nothing), retribution

Also bring scourge sacrifice, so he'll kill himself even faster when sacrificing health.

here's how i got him:

take useless monk enchants wich wont do much for him or you healing breeze and rend enchants before entering use the monk enchants on you when you go in he will use rend enchants and kill himself cast em again and watch him do it again :P

Any Necro primary or secondary can beat the dopelganger in under 10 seconds, and do it with just two spells:

Awaken the Blood
Verata's Aura

The dopple will cast AtB, VA, AtB, VA and die instantly the second time VA is cast.

Remember this: N/* or */N. Two spells. Under 10 sec.

retribution, dark pact, awaken the blood, price of failure

Thats all you need

I do not have access to Verata's Aura skill. It is located in Copperhammer Mines, but I am still in Augury Rock.

I have tried this combination. It is better then before, now I can take 70 % XP from him and then my character die
