Serpentine Sorceress

"Black Magic is especially strong around high Aether and runic areas, it's perfect for practicing. The goal with Black Magic is to try to quicken cast time as much as possible. This is achievable with certain Materia, but it's more optimal to try and train the body to adjust to it. It's not recommended for all casters...Forcing your Aether even a little more than you can keep up with could prove fatal..." -Valybel
