So, I was done playing for the night and decided to goof off a bit. So I saved and then went to blowup Ancano (in the college of Winterhold) because he bugs me.
I gave him both barrels of my Fire Spell and he just stood there. Shot him till he knelt down and then after a bit he came back up ready for more.
I did not think too much of it until I leveled up my Destruction skill by doing this.
So my question is... will anyone in Skyrim care? Is it just because this guy is a jerk that no one seems to mind that I flambé him? (Doubtful)
Or can you practice on any essential character with out fear of getting in trouble?
Here is a screen shot of me blasting him. If you look close, you can see that there is someone sitting in the background (by the window) and he does not care. (In case it matters, I am at the "Get the Staff" part of the Winterhold quest.)
