Ok, my N/E went to duel my doppleganger yesterday, but he had skills that I did not!
When I went in, he started shooting ARROWS at me! Each of which hit for about 25% of my hit points!!! Needless to say, I didn't last very long. I wasn't even carrying a bow!

I re-entered a number of times with different skill sets, trying to beat him down as well as bumping up my armor against those arrows. I was doing better, then he started using HEALING SIGNET!!!!! UGH!

Is it my mistake, or is the doppleganger supposed to be a duplicate of your own character?
I finally entered with only 3 skills equipped, all elementalist. Stone daggers, obsidian flame, and one of the armor enhancements. With just these skills equipped, he no longer shot arrows at me and I was able to defeat him.
I had also previously tried doing the necro sacrifice-himself-to-death trick, but he never sacrificed, just kept shooting arrows!

Is this normal, or did something get whacked out?
Any thoughts?
