So, question: How much of a healer is Saleh, really? I was told FE sages aren't healers....?

In any case, Frey has a large amount of healing magic he will be capable of useing, and will be requesting rune scrolls. I'm pretty sure Selphie and Ceodore do, too.

He also, at some point, will be tossing out a one off attack similar to a limit break/overdrive/special attack that can attack a full unit of soldiers while healing their own.
