Arte Description and History
When the Storm Edge arte is used, the character draws back on their bow and releases a concentrated stream of arrows in one direction. In Tales of the Abyss, this arte can be used in a Fire or Light FOF Circle to alter it into Blast Edge. Blast Edge retains Storm Edge's multiple arrows, but it instead fans them out to cover more ground, and coats them in fire.
