Ether Assault

Ether Assault is the first skill in 's Confidence skill branch. It makes damaging ether arts 20% stronger.

Overview
An extra 20% damage for free is pretty darn good. The problem is that Sharla is literally the worst party member to have it, as she only has one (1) (uno) (ichi) such art in Thunder Bullet, whereas everyone else has at least two (except Reyn, but his is area-of-effect so even it is arguably better). So despite it not being all that cheap to link, it's far more useful linked than on Sharla herself. Melia and Riki make the best use of it.
