READ IF YOU DONT WANT TO WATCH THE VIDEO
TY to Sommi for making this in the comments i edited it a bit
Didn't say it in the video on Why barret has first strike so you can do quick buffs at the start of a fight
barrier or haste u can choose
CLOUD Weapon MATERIA [HardEdge] //w ChainBangle + Gotterdamerung (alternative is Champion Belt)
Prayer + Steadfast block + First strike + Lucky up + Luck up (Boost crit chance) + Healing + Refocus + Parry + HP up + HP up
(If you don't have Gottemsburg item, then replace Re-Focus Materia with anything, example MP-Up)
AERIS MATERIA [Mythril Rod] w// Force Braclet + Circlet
Healing + Fire + Ice + LIghtning + 2x MP-Up + 2x MAgic-Up + Prayer Materia + Revival You could also Replace 1 Magic up with + Magnify Magic That way you could use curaga and you're whole party
BARRETT Materia [Big Bertha] //w Cog Bangle + Crescent Moon Charm
Healing + Prayer + HP-Up + First-Strike + MP-Up + Time-Materia (Haste) + Barrier + Revival + MP-UP
TIFA = Party HoeBag. If someone is out of your party, Copy-Paste all their Materia into TIFA
equipped w/ Metal Knuckles and then Supreme Bracer + Crescent Moon Charm
Fire + Ice + Lightning + 2x MP-Up + Prayer + Healing + First-Strike + HP-Up
Also if u want to make it safer for youre whole party use (Magnify Materia ) this turn any spell into a aoe one so curaga will heal more then 1 person barrier will buff more people same with haste make sure u switch you're materia around depending on the fight be warned tho as this will make the game even easier to complete
