So I'm liking +atk/-res SF!Nino so far but I'm wondering what C skill she should use as I don't have any flier buff fodder currently? Right now her set is her default kit but with Desperation 2 replacing Aerobatics. And yes unfortunately I'm stuck with only Desperation 2 currently as I'm having a major shortage when it comes to summoning Shannas. SF!Nino, Ishtar, Micaiah, and Caeda are all currently stuck with Desperation 2 because of it.
When it comes to C skills I do know for certain I have Atk Smoke and Drive Spd options as fodder for SF!Nino but unsure what to give her? There's also a decent chance she'll see use on both flier and mixed teams. Thanks in advanced for any suggestions!
The first skill that comes to mind is actually Karla's Even Spd Wave, sadly, but that's because I think it fits SF!Nino perfectly. Out of those two you mentioned, Drive Spd 3 is way easier to find than Atk Smoke 3, you just need a 4* Tailtyu, so you could try that out if you're willing to spend some extra SP and a Tailtyu. But, to be honest, I think it depends on the team you're trying to build. Do you have any teams in mind?
