Sheena suggestions please?

Wary Fighter + Fortress def, Fortress res, or QR seal and Ignis. That's what held me up for months until I got VF and Aether.

Eventually, the best EP Sheena build is Special Fighter + Aether + QR at max merge.

You can spend months of feathers on her, but 1-1.5 months of orbs is too much for the fodder? I don't see the logic in spending that much on a unit and trying to cheap out on fodder.

I'm hoarding feathers to do a Sheena merge as as well, still need 4 more copies of her though. Definitely gonna go Steady Breath, Wary Fighter, Bonfire, probably ATK smoke. I got lucky and somehow pulled 7 Brave Ikes so I dont mind giving her steady breath. If not I'd give her close defense. All the new fighter skills will have to wait a while until I get lucky enough to pull them. I might just give her a defensive special so she can tank and weaken enemies for the bonus unit to pick off.
