Low lvl m/n doppleganger

Hey, I'm lvl 14, got rushed through, and I'm having some trouble killing my mirror. I was told to use illusion of weakness and backfire, or just a lot of sac skills. Any suggestions?

Thx. Sapper

Try combining Backfire with Sac skills. Awaken the Blood helps speed along the process.

Remember, you're not supposed to cast anything.

I beat at level 13. I brought abunch of hexes that slowed foes and shatter hex. When it starts, run right up next to dopple. He'll start rotating through hexing you. You simply Shatter Hex to damage him. Took me 3 Shatters I think. Just don't bring backfire if you do it this way, or you're dead.

Sacraficial skills+awaken the blood
Illusion of Weakness to speed up the process

YOU DONT USE ANY SKILLS,let dopple kill himself (speed the process by hitting him)
