Ability Boosts and Flaws
Boosts raise ability scores by 2 each; flaws reduce by 2. Four free boosts at creation plus boosts from ancestry/background/class.
The six ability scores — Strength, Dexterity, Constitution, Intelligence, Wisdom, Charisma — start at 10. Boosts raise a score; flaws lower one. Each boost increases a score by 2 (or 1 if it's already 18+). Flaws decrease by 2.
At character creation you receive boosts from ancestry, background, class key ability, and four free boosts. During play, every 5 levels you gain four more free boosts (max score 20 before apex items, 22 after).
Ability modifiers = (score − 10) / 2, rounded down. They apply to attack rolls, saves, skill checks, and ability DCs.
