Just when I was having fun and the game was finally opening up, Sekiro closes off all paths and drops another wall of a boss in front of you. Seriously, fuck SPOILER, not only is he another beefy multi-phase boss, he also either oneshots you or (if you ground out for HP upgrades) one-combos you if you make a single mistake all fight. I've died to him a good 60-70 times, I have all his combos down to memory, but it doesn't matter when I need to chip him down over thirty + hits per bar while he only needs to hit me twice to murder me and every attack stunlocks you if you don't block it. Heck, even if you perfecly deflect his full combo he leaves you with the posture bar half-filled.
And sure, this may be par for the course on soulsborne games, but again other soulsborne games don't punish you if you fucking die more than twice.
