I agree with Bowler1 -- it seemed unrealistic because there didn't seem to be any real set-up for the fight. I like the premise of the piece though and I thought you did a good job at conveying character.

From the second paragraph onwards, there seemed to be a bit of awkwardness with the flow of your writing too, so you might want to take a look at that. The over-telling with things like "bumped into the massive troll" etc. also knocked me out of the story. It was almost like you were turning to address the reader.
