Skill: Athletics
Athletics is a character's ability to use one of the oldest tools known to many civilizations to complete a task: one's strength. Skill checks and actions involving Athletics involve lifting, dragging, or carrying things; as well as throwing, tossing, or simply prying things open. Mechanically, Athletics is the primary skill used for engaging in Grapples | ◈ and Shoving | ◈. Skill talents involving Athletics expand Atheltics reach and ability to cover more bases, allowing the strong to be that much stronger.
Atheltics only uses STR / Strength by default. Athletics is a Primary Skill, meaning it is a major skill that can only be gained by mechanics that grant proficiency.
