Walter said:Getting his tail is much, much harder than taking him down. I tried doing it a number of times before looking up the stats on the weapon that drops and seeing it wasn't worth it for my build, gave up.
I gave up as well, its really hard to score hits on his tail. I was trying with halberds, black knight greatsword, doing vertical swoops, but didn't manage to get his tail once , I tried maybe 20 - 30 times before I gave up and killed the bastard. Still, interesting boss
