Art...

[ And yet, here she was, putting him through his paces. Before, Cloud would have said something along the lines of, "There's no room for art on the battlefield. It's about who gets the job done first, with or without the finesse."

In a way. I told you how there were different types of Materia. You see how my Buster Sword has two holes at the base of the blade? You can pair two different Materia to create different outcomes.

If I put a Lightning Materia and Elemental Materia in the slots, not only could I cast spells, but my sword would be imbued with lightning itself.
