Final Fantasy XIII passive abilities

White Mage: Life's refreshing breeze, blow in energy! Cure!

This article can be improved in areas such as listing all abilities and not grouping them together: an example would be HP: +◯, flavor text from the game should be italicized.
Please refer to the Manual of Style or editing help to get started.

This is a full list of passive abilities in Final Fantasy XIII. Passive abilities automatically take effect on party members equipped with a certain accessory or weapon.

Note on stacking abilities

HP: +50   HP: +50 ⇨ HP: +100

Resist Fire: +10%   Resist Fire: +10% ⇨ Resist Fire: +19% ↓ ↑ Fire Damage ×0.9 × Fire Damage ×0.9 = Fire Damage ×0.81

When increasing character parameters (HP, Strength, and Magic), abilities stack normally.

When increasing character resistances (Fire, Physical, Damage, Deprotect, etc.), the percentages are subtracted from 100% and multiplied together.

Abilities without numerical values do not stack.
