For my own reference mostly! But if anyone else wants to look at it: Raven's fighting style is a bit weird. He uses a bow in general, but can switch to a knife at close range once he learns a skill (Change Style), and he also has some magic. This is a list of all his special attacks, by category! He also generally doesn't say his attack names, like most other characters do, and has fairly interesting spell "incantations." I have included what he says when performing some of the attacks for your edification and entertainment. /o/
