Term: Primary Skill
A Primary Skill is a major mechanic in this game that represents a creature's ability to interact with the world. Primary skills are often given at character/creature creation. For players, they are only given by Ancestries, Backgrounds, Classes, or features. They are seldom given by other means, and while they can be changed via @[Character Progression](article:f564534a-98fe-4a69-ac76-36099658a825, a player usually can't get more than they're initially allotted.
