There's lot of mistake but for a first clear (6 tries total) that's definitely good enough to showcase how the boss works !
I'm not using Cait FSB6 in P2 because P3 is so bulky that it's better to bruteforce P2 buff and debuff P3 for me lol.
Funfact : Because i use Cait, Edge is overall pretty weak in term of damage since nothing "magical" works with NIN, but he's still does so many hits + AASB Chase that it's not even an issue :')
