Light BardingArmor 0

Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.

You can purchase special armor for animals, called barding. All animals have a trained proficiency rank in light barding, and combat-trained animals are trained in heavy barding. Barding uses the same rules as armor except for the following. The Price and Bulk of barding depend on the animal's size. Unlike for a suit of armor, barding's Strength entry is listed as a modifier, not a score. Barding can't be etched with magic runes, though special magical barding might be available.

An item with this trait can be worn by an animal companion or similar creature. A companion can have up to two items invested.
