Ok I have kh Riku and kh Riku black coat both at 6* and max 5 yellow five stars , now I have few 3 and 4 star doubles and planning to take them to 6* so I can fuse them into my 6* to get those I guess you guys call them guilt ? Should I fuse one at a time or all together ? And what % am I. Looking at ?
Thanks in advance
