Anyway, the new scans also say something about different skills, and how you can equip them, correct me if I'm wrong, but I think these could work similar to the arts in xenoblade (original and x), with you being able to activate different attacks, or maybe healing, or inflicting a status ailment, it's a long stretch, but it's possible.
