I am in charge of deciding the name of a skill in a role-playing game that serves as a catch-all for abilities/skills that are otherwise unlisted in our handbook (think skills that will help players flesh-out their character's personality, quirks, and life).  Such a skill could be a profession type, a craft (e.g.,whittling), or something more exotic like hyperlexia.

- `Profession` and `Craft` do not capture the spirit well enough.
- `Ability` seems too generic, as are its multi-word variants, e.g. `Unlisted Ability`.
- `Knack` seems closer to the mark but open to suggestions.
