Do I spam raid the 30 stamina quest and fuse it with 4* Zabuza's or do I turn these 4* to 5* then fuse them together? Would I yield an efficient luck stat gain?
PS: 4* Zabuza, when fused with same 4*, it only gains 1 luck per enchance. Do I turn them to 5* first then fuse to get a higher luck stat gain?
