Skyrim is exhausting sometimes

So there I was, on my level 5 (newly created) mage, just trying to steal a dragon's word. I had Lydia with me, and I was pretty confident that I wouldn't hit her with my dual casted lightning bolts, so she might even survive the encounter.

Unfortunately, the dragon wall I was trying to rob was also the one sheltering the dragon priest Krosis.

Shit.

I discovered this halfway through the fight. After straying too close to the dragon wall, Krosis pop's out (undeteced by me) and summons a frost atronoch, which then greeted me with a hearty high five. To the face.

So the dragon on it's own would have taken me close to 10 minutes to kill.

Krosis, on the other hand, dragged the fight out for an hour and a half.

And all I got was a crappy lockpicking mask...
