i'm having troubles beating my mirror in Prophecies. I'm an A/W. no matter what i bring, the Doppelganger's attacks take more off me, and he always ends up poisoning me.
Drop your poison skill, make sure you don't have any assassin interrupts or warrior knockdowns, and just go toe to toe with him. Bring healing signet but don't use it, and bring Temple Strike if you can. Using it blinds him, and it's more or less over.
Not too useful, he'd break out his bow instead of chasing you. As the others have said before bring frenzy and heal sig. Really shouldn't be a problem with those skills. With a combo of Unsuspecting Strike + Fox Fangs + Horns of the Ox he should go down in no time.
I used disrupting stab and shadow refuge. I disrupted his refuge, and made sure to only use refuge right after he used disrupting stab. Other than that I just wailed away for mission and bonus
