I was rocking dual great katanas pretty much the whole DLC but this absolute monster made me switch back to my base game weapons to be able to land a couple more hits.

After 10 hours between yesterday and today, I've finally beat him, no summons just me and this insanely poor Twin Princes cosplay on steroids. The only boss that trapped me this hard was Isshin (Sekiro was my first souls game) for about the same amount of time.

This guy doesn't give a single ♥♥♥♥. I managed to get good at dodging consistently almost every single move of his but after all that, it still doesn't feel satisfying. Because I truly think that you got to have some good RNG on the second phase to not get 1/2 free hits from time to time (that cross Slash is just ♥♥♥♥♥♥♥♥, dodge-able but still ♥♥♥♥♥♥♥♥). Depending on where you are, you cannot always fully avoid that 4-slash teleport combo. Oh and if you missed the dodge and he pulls you with the gravitational field? You better be Full HP or have some next level reflexes to dodge that otherwise you're done.
