I beat it on like my 3rd go.
but its funny I still haven't beat the 2nd last boss, even though I got to it now on 3 of my characters. (steam says 174 hours but I do leave it running sometimes).
and yet don't think Ive seen anyone else complain about this boss. it cheeses me off too much when a boss 1 hits me and takes along time to get to from bonfire, so I've actually had less attempts than previous bosses like pontiff/dancer.
cheeses me off to the point I basically seem to just make a new character. but I guess I could just summon it so I can see last area(s) of the game.
