[quote=Jerkchicken]Hey momotaros, tell me about the mystic artes and how they worked in version 1[/quote]
A Mystic Arte is unique to each character. We didn't actually get far enough to use them, but it's your one chance to overpower a skill. Uses are incredibly limited and your level restricts its power, but it was going to be a super-move to trump simple artes or survive a desperate situation.

[quote=Mizuho]Why do you care so much about mystic artes that may or may not be returning ._.[/quote]
Because I'm already planning for a situation in which Tyrell uses "The Thief Lord" entirely on emotion. I want my chance to look cool, you know?
