My ideal endgame FOnewearl equips for nuking/support are:
Psycho Bridge(for nuking RA techs&tech cost reduction)
Dark Bridge(for Zalure boost&Grants boost)
Glide Divine(for Jellen/Zalure boost)
Glide Divine v00(Simple tech boost)
Tyrell's Parasol(Shifta,Deband,Resta,& [i think]Anti boost)
MotherGarb+(cuts tech costs by 50% and boosts Grants sometimes by 10% iirc)
Adepts (each one cuts tech costs by 25%, i equip 3 total)
v801(to cast techs faster)
Noob/HP(i always carry 4 for that HP boost, which is really needed for FOneys)
Hylian Shield(Rafoie/Razonde/Grants boost)
Rabarta Merge(Rabarta boosted by 35%)
Foie Merge(Foie boosted by 35%,I use for Sil Dragon&Dark Falz final form)
For melee:
Banana Cannon set(for mobs, Blizzard special)
Hundred Souls set(for small mobs or single enemies& vol opt gizonde glitch)
Lindcray set(ranged high atp wep w/spirit special)
Rage De Glace(highest atp mech-type weapon FOneys can use,Blizzard special)
Slicer of Fanatic(mid range demon weapon)
Slice of Vengeance(mid range high atp weapon w/Charge)
TypeME/Mechgun Demon(for high hp enemies close by)
Ultima Reaper(unreduced Hell special,decent atp for mobs&can hit a lot of enemies)
TypeGU/Mechgun Hell(if you dont want to use Megid)
Vivienne set(multi-hit weapon for single enemies/bosses)
Holy Ray(long range arrest weapon)
Bringers Rifle(long range demon wep is better for some situations)
Sacred Cloth(for built-in Cure/Paralysis so you dont have to equip one in the unit slot)
Sonic Team Armor(+80 to all resists&highest def/evp armor in the game)
Kroe's Sweater(+10 ata boost)
Centurion/Battle(+%110 attack increase)
Smartlink(raises ata for long range weps for HU/FO)
V502(raises the chance of special attacks to hit)
Wizard/Resist(+15 to all resists, good for some situations, e.g. Falz 2nd form,Epsilons)
Red Ring(+20ata & boosts to all other stats) or halloween costume series
-Frank the Bunny Costume(built-in Jellen/Zalure boost so you dont have to keep switching to Glide Divine)
-Guardian Angel Costume(built-in Resta/Anti boost so you dont have to keep switching to Tyrells Parasol)
-Bewbs Costume(built-in Trap/Search so you dont have to use one in a unit slot)
Anti-Dark Ring(high EDK boost)
