So as one of the final bosses in Bloodborne, I found Mergo’s Wet Nurse rather easy. In fact she/he is the only boss I one shot first time through. Even the freakin’ Celestial Emissary killed me once, so believe me when I say I am no pro. The strategy I employed was to just work my way behind the boss and Paul Bunyan the hell out of that ass. Good luck hunter and may the good blood continue to guide your way.
