Ah, *that* dude! If you dont mind a bit of spoilers:
The "renew" move to clear debuffs and "suppression" skill (that you get from defeating A.X.S.U in combat) should help a lot in this fight! Also spacebar helps you quick pause :D
ohhhhhh ok alright yeah no won't lie i had never used the pause mechanic in the fights at all and that actually helped alot. I was able to get through thanks to you!
