Love the game but I believe I have some across a bug.
On my second play through I decided I would tell the gnome artificer that I worked for the boss. This got me involved in a fight, which I tried to run away from (Eladrin Monk with Fey Step and 40' of movement). Not only couldn't I escape, but I also couldn't be killed and got stuck in a loop where he just kept attacking me well after he had removed all my hit points.
Very much an edge case but I thought you should know.
