Champions of the Sun
Natural soak: Characters can use their natural toughness to resist some amount of damage—a burly sailor or battleconditioned soldier can shrug off more abuse than a small child or an overweight savant. As a result, all characters gain natural soak equal to their Stamina rating.
Armor soak: A character wearing armor enjoys the value provided by the armor, in addition to his natural soak—see page 591 for a list of different armor types.
Total soak: A character’s overall soak total is (her natural soak + her armor soak).
Using soak: Soak is only applied against withering attacks, representing the difficulty of gaining a decisive advantage against a sturdy or well-armored target.
