The 3rd phase is killing me, by the time I manage to get back to him after the 2nd phase i'm literally just dead
Might have to give it a break and revisit as ive literally spent days trying to do it!
Ive tried them, they were helpful until I ran out of spirit emblems, and also got no coins left
Take a break and try again after a few days if you're not feeling it.
The first two phases can be perfected enough that you'll have enough leeway for mistakes in the third. Treat them like a spar and work on your timing and responses to what he does. DO NOT LET HIM BREATHE, I cannot stress that enough
Remember it's a rhythm game and stay aggressive, you aren't supposed to let him recover his posture. You can learn his limited responses to your offense as he gets more predictable when pressured and reach the third phase consistently.That's when you'll get him. Just don't be afraid to go in, you might be struggling because you're unnecessarily prolonging the fight by being more passive than you should.
Are you using the lightning reversal in the third phase? Jump, get hit in mid-air and attack, you'll reverse the lightning and do massive posture dmg. He also always opens up with a lunging thrust, be ready to always Mikiri that.
Look up FightingCowboy's guide on YT, you'll notice how he stays on him and even though the guy doesn't have great reflexes and makes mistakes, he still beats him without prosthetics. You don't need anything but your sword for this, it's more manageable than you think, you just probably respond incorrectly to certain attacks and leave dmg on the table. First time it took me like 20 tries to kill him, I went through the game four times and never died to him once after that
There's even enough time to see if he's going for the perilous thrust or sweep in the second phase. He trusts -> Mikiri, he sweeps -> Mario jump him. Don't let him do it for free by just avoiding it, he has to pay with posture damage. But even if you can't react to that, no biggie. You can still win.
You can be even more aggressive than him, I was IIRC
I don't actually agree with him about more patience bit, you can wail on him hard and still have time to parry his response, but I do have slightly above average reflexes and pattern reading to be fair so that definitely helps.
Worst case scenario, just drop it, no point in playing something that causes you grief
Still, I refuse to believe you can't do it after beating Bloodborne + DLC, you've probably haven't learned his moves yet or need to tighten up your parry timing.
Meanwhile, I'm going back to Demon's Souls Remake, play some BGIII and cool your head
