I’ve also been using Kurasame from FF Type-0. I have all of his weapons maxed out. His Hyoro debuff is quite good that stacks if the enemy is confused, asleep, or paralyzed. If an enemy acts with 5 Stacks of his debuff, it will reset back to 1 unless they cannot act then it will remain at 5 stacks after its turn ends. His BT effect also makes it keeps his stacks from going down.
