Hi guys, a newbie here and I've got quite a few questions.
So I read a few guides about making a stronger medals by fusing the same type of medals together.
Currently I have two 3*Valor Form Sora and another two 4*Valor Form Sora medals.
If I were to fuse them, should I start fusing the 3* ones first then evolve it to 4* so I can fuse it alongside with the rest of the 4*?
Ooorr...
Should I just evolve all the 3* into 4* immediately then just fuse them all together afterwards?
Another question would be should I max ALL of their level first? D:
