You should
test Barbed Crescent extensively because a quick check of the spell against fully leveled Abyssea mobs
suggests that the floored accuracy does not apply to said spell anymore. Although only one cast landed the debuff without cruor buffs, using cruor buffs (No atmas) seemed to have a consistent landing rate. The difference between no cruor buffs and cruor buffs is roughly 35mACC within Heroes zones.
If that is what's necessary to land some of these spells now, that's much better than floored magic accuracy. That said,
needs more testing, but the
preliminary results look great for barbed crescent.
