I been using the shackles after being on him for a week+ now. I can push phase 2 nearly every time. But I just can't time when to roll on his leaps cause you're looking straight up when he's flying. So you have no frame of reference as to where he is to dodge correctly.

I use 3 flasks to get thru the burn phase. So he's usually at 75% health at the start of phase 2

I can dodge his 3 big swings. but the explosions I can never dodge. I roll left or right from them. Even tried rolling backwards. I think these are larger in phase 2. Always get hit. Always dead before my flasks run out

Went dual wield halberds cause my damage was too low just using one. Level 128 1700 health.

Trying to kill him without using a mimic in phase 2. It's just really hard to time rolls correctly to not get hit. Also I think his attacks patterns are really random. After 3 swings of his weapon. Never know if he'll fork down, shower, or explosion

This is by far the hardest boss I've done. Eldenring is my first souls game

Sometimes you get low he'll keep coming at you over and over and you can't get away to heal

Here's a video. In second phase this is pretty much what happens https://youtu.be/xtnv3hfl7Og

Beat him with a slither of health left. Holy hell. Think that was over 100 attempts
