I just blew most of my best save for final boss items on Ape pt.2 to try to get the last few hits.
Still died.
Fuck this game I'm out. Sekiro beat me.
I can do ape pt.1 almost no damage at this point but I can't beat pt.2 for the life of me. I can deflect all his shit but none of that matters since you can't kill him by deflection. I can avoid his terror stuff with terror guard but whenever I get in and do damage I take damage. I just can't deal with pt.2. This is the hardest boss in the game easily so far.
This is so odd, Ape p.2 is one of the easiest bosses for me (i know this doesn't help).
Consider that it has only one attack that is truly dangerous, and that's the scream.
Once you learn to recognize that sort of weavy animation of the ape getting its head up to scream (and see the perilous attack symbol), just run (not dodge, run) backwards directly away from it, and wait it out (use that moment to heal if you have to).
Any other perilous attack it has, is something you have to jump (i don't even think it has a grab in p.2), so just jump when you see the symbol, and keep hacking away at it.
When he jumps way up high off screen and the perilous symbol appears, wait for it to start coming down and then jump also, that's also a sweep but it's easy to avoid once you know.
Everything else is just deflectable, so just stay close and spam block, trying to learn the timings of combos will help make it go faster, but spamming usually work good enough at first.
Other important attacks to keep track of:
1) The lunge forward with one swipe (where it ends up on its belly) can be deflected, but it's probably easier to dodge into, so you can punish severely.
2) The one where it gets all vertical with the sword held up high and just topples down on you is the one you gotta look forward to deflect, as it stuns it majorly, and then you can double tap the spear on its open neck/torso for massive posture damage.
3) Its standard combo is the 4 attack "dance-like" thrusts (but are normal attacks) and those are also good and easy to deflect.
4) If you stay close it has a couple of other combos, but they're all sword attacks that you can just spam block to, and if you deflect enough of them, it'll either scream you away, or (ideally) do (2), which is what you want, for the afore mentioned reason.
You don't need anything particular for this fight, but the spear with the pull combo (double tap of R2) helps make it faster.
