Yeah I feel like it would be a nice in-between option for ya, as you mentioned the second phase troubles in your edit. It really is harder to learn a second phase when you’re only getting through the first on every 5th try or so (Laxasia was a pain in the ass for this, I never really got a good feel for phase 2, just managed it somehow on a lucky run with wild and terrified inputs haha)
I think having Sekiro as my first soulslike taught me that there’s a big gap between surviving a phase and really nailing a phase though, so I try to take that with me and get phase 1 to point of just warming up. And looking for more and more windows to inflict damage - it’s amazing how quick some of the fights can be when you find more of them
Haha well as much as that mindset helped me (and yes transformed some Sekiro fights from hard as hell to seeing how quickly I could put them down), a lot of Lies of P still came down to desparate messy scraps for survival. Especially in NG+, I got smashed by that damn green monster so hard
