Owl is annoying me. 10 tries I think. I have him beat in my head. It's just the execution that I have to get right. What I find somewhat annoying is, sometimes if you miss a deflect on the first part of a combo, it's hard/impossible? to time the next and successive deflects.
Other than that and learning not to get dusted (heh), he has ginormous "do damage to me" windows.
Some attacks deflecting actually seems counterproductive. Like his big overhand slash. You deflect but it still staggers you back and you both recover about the same time. Versus dodging which lets you deal some damage. An example where dodging is the superior choice over deflect and jump.
Also part of the game seems to be 'learn which attacks have hyperarmor and which don't." Like Genichiro you can stumble him in the middle of many opening attacks, and some of his rush attacks and tool start ups. But others, no. Like Genichiro, when I again reminded myself to be aggressive and just get in his face, I started noticing all the times he could be interrupted before he starts something up. Figuring out which is which and what you can and can't do is part of the challenge, but also sometimes part of the annoyance. Even though it's like every other From Soft game in spirit, the pace at which it happens tends to amp up your anger.
Also apparently everyone is laughing at Gamespot because one of their writers thinks Sekiro not having an easy mode is "disrespectful" to its fans. It's probably just some clickbait nonsense more than anything, but a few journo outlets have complained about the difficulty. I dunno, I can profess that I have a lot of weird ego invested in my performance in Sekiro, more than Dark Souls PvE. My attitude to how I do in Sekiro kind of reminds me my attitude in PvP, it kind of triggers me the same way.
Also also, and maybe this is me reading too much in to it, but in the above fight having to avoid using that one specific move has kind of shown me...against standard sword bearing opponents, using partially charged strikes to change up your timing actually seems to fuck with them a little bit.
Like, the game knows exactly how fast you can throw your combo, and it has responses built around that conceit. So let's say you're doing the three hit R1 combo. Game knows that, if the first one hits it can block or deflect up the second, then do its return attack. But if after the first hit you start charging the second, the boss AI goes "well ok then I'll attack now" and right as he starts to move you let go of that charged attack and you go in to a normal strike rather than the full charged thrust attack. Since the boss is now committed to an attack animation, your follow up strike hits, and hopefully, based on the attack they're doing, stumbles them. And instead of just immediately R1ing again, which will cause them to go in to the block/deflect routine, you hesitate again.
It's this weird timing you occasionally stumble in to it when, I feel like, you've finally had enough of a bosses' shit and/or remembered/realized that you need to be aggressive, and you walk up and just start wailing on them like you have no fucks left to give.
