I fought in the Sewers, And I left my loots behind me To go looking for some rats to kill, And it wasn't very long
before I encounted this Chosen Hunter who tried to kill me. I fought back, then had to run. I came back and sneak attacked him and got him to near death before he too ran away, into a wall twice, then down a corridor. I later encountered him at full health about 3 minutes later and fought him, but at one point he stopped pursing or fighting or moving. I was able to get him down to near death again like this before he ran into the same wall as before and promptly died.
