A Class-access exception
Princess can equip gear and abilities regardless of Class. Its named abilities include Critter Chatter, Sonic Soul and Distress.
Not a universal bypass
Color, level, capacity and resource requirements still apply unless a specific ability or item states otherwise. Princess does not automatically grant an entire class pool.
Story identity
Princess can look like storybook royalty or the self-appointed ruler of an eccentric party. The identity comes from the equipment and abilities chosen together, not from a mandatory social rank.
Open specialization
An open Spec can pair with any Class. Choose it in the Spec field; its special permission applies only while that path is selected. It does not replace the underlying Class progression or the rest of the character structure.
