Confident Aim and Spells?

[Greensleeve]

I've been toying with a spell-slinging Fighter, to make up for the lack of AoE. Lore is the obvious solution and there are some great spell-bound items around. Next thought was, of course, synergy. 

 

So, Confident Aim. By its description, I would say it should function with spells, regardless of them being scrolls or spell-bound in origin. But there are things that don't quite function as I would guess from their description, and this might be one of them. 

 

So before I run off to do some testing, I figured I'd go here and simply ask. Does anyone know if Confident Aim works with spells?
