guard a little later than you think you have to; unlocking the camera might help your timing too

I'm playing on version 1.8, first playtrough lvl 85, hardest difficulity. I'm trying to defeat the boss without the star fragment help.

How to perfect parry him? I can't seem to get the timing right, it's weird

he has a fall down animation where his body drops to the ground. I can dodge it by running away and pressing the dodge button but it's often hit/miss. If you parry him he should get stunned by this attack but it's almost impossible for me to hit it at right time.

absolute defence and absolute counter atack have way more parry frame if you struggling.
athough it is tied to using greatsword of fate handle or umbrella.

just have to keep trying and adjusting the timing. You can use perfect parry grindstone to get through part of it, but not all of it. Or weapon w absolute defense/ counter skill.

A lot of the slower attacks, like the fall, you try letting it pass a bit more and parry later. But there def are some quick ones that you have to watch out for, like when he swings with his smaller spear.

for that fall, I look at the animation and check for a specific part, he is heavily leaned forward and about to crash, but not quite there, then I press. ( his fall starts slow then begins to acelerate). The fall animation is really noticable, just keep adjusting and looking for specific parts. If you pull off the guard and nothing happens, you need to wait more. If you dont get to guard and just get hit, you need to be earlier. Its more generous than you think imo. Once you see it, you can be consistent kinda fast.

also, you can break his horn ( the head or hand one) you can create a weakspot.

No need to guard, it's another dodge boss. Dodge into his body and attack.

You do want to parry his fury attacks though. They leave him wide open for a lot of attacks.
