Close, Yoherz.
OL is basically a temporary stat booster (like Trance), and it prevents the user from flinching for a short amount of time (this effect is useless once you get the AD Skill Glory). If you have the AD Skill that compliments OL called "Special", when you meet the proper conditions, you can pull off a Mystic Arte. In exchange for pulling off one, you immediately go out of OL.
Trance works differently, where it lasts a certain number of actions. Most members get 3, but Quinna for some reason gets 2. Oo
