Still playing Nioh 2. I'm at the Depths of the Underworld, the very hardest section of the game. I'm on Floor 13 out of a total of 30. At this point in the game, each floor ends with 2 successive boss fights, and the bosses have life drain on their attacks. My gear has let me cruise through a majority of the game, but holy shit is this becoming tough now. I'm either going to have to redo my build, really start to get better at recognizing all boss patterns, or hope that the upgrading perks that I haven't gotten yet are substantial.
I'm just glad I've made it this far without resorting to a build guide or anything.
