Thread: Question on Break Limit-mechanic

I want to use "Break Limit" on a weapon.

Is it helpful to level both weapons to their maximum level and then fusing them to receive a better result?

And as I am already asking a probably dumb question, here is another one. Why are some eidolons and weapons labeld at +x? Did those items just roll better or are there certain mechanics to get a better item?

Doesn't matter what level you break limit something results are the same in the end.

+X gives bonus stats. For every +1, you get +1 ATK and +3 HP. Stacks up to +99 and can be transfer through using that as enhance material on the unit/weapon you want it on. Kamihimes can get the +X bonus from weapons.
