Finally, I get my green mage hero... A bit late because I just promoted Nino too 5* before, but I won't be difficult this time ^^
I was thinking of a build with fury + renewall, but it seems most of build use a tomebreaker.
So, what is the best slot-B for her ?
Julia's main job is as a magic check. Because of her color and high atk and res (even as bane), she can deal with blue mages without inheritance. To expand the list of units Julia can defeat, G. Tomebreaker is optimal as it stops other green mages from doubling and defeating her while she gets two attacks on said mages which puts them in her kill range.
Probably green tomebreaker. In arena, you're most likely to encounter maybe a blue and green mage in one team, so green tomebreaker will stop the green tome user. However, rather than fury, I think you should go for triangle adept, because fast blue mages like Delthea can hit Julia kinda hard, but Triangle adept prevents that, plus she she'll die to anything red anyways.
