I figured we were allowed to share characters, but not items? If so...
50 Cloud/Tifa/Aerith/Sephiroth/Tyro/Rydia (Ice Whip)
Only personal 5* I own is the ice whip.
Other 5* Genji Helm/Shield. Judgement Staff. Regal Gown
And upgraded 3-4* weapons and armor to 5* like
Maneater, Crystal Sword, Ancient Sword, Rune Axe, Giant Axe, Diamond Knuckles, Moonring Blade, Gold Hairpin, Royal Crown, Thornlet, Rune Armband
I do have a couple other soul break changing items, but they kind of suck atm: Gaia Robe and something else I cant recall.
Spells. Dragon level 2, Shiva level 2, Comet 4 charges, Curaga 8 charges, Cura 8 charges, Lightning Strike 6 charges, Drain strikex2 4 charges, blind attack, blind buster, etc..etc.. all the staples and a few more summons but those are the best. Ill update it later with all the precise info.
