I made an alt and have brave hector and Celica on main. Which ones of Veronica and ephraim should I pick?
It honestly depends on what you need in your team. Veronica is great especially in Arena (and Aether Raids I suppose) and essentially acts as a colourless mage, but if you don't have an axe unit and want someone to complement Hector, then Ephraim is good.
Personally, I would probably choose Veronica but it's totally up to you.
I'd go with Veronica. She has unmatched utility, damage, and mobility.
Ephraim is amazing but for general purpose, he's not as ideal as Veronica since he wants a rally or another armor and also wants DC. I'd argue L! Hector is better as far as axe armors go for general purpose.
