Immunity ability

Proof is a series of Elemental and Status abilities throughout the series, though they are not named until Final Fantasy X. They are usually referred to as "Nullifying" abilities, such as Null Lightning, or simply just prevention. They have been around since the original Final Fantasy and has appeared in every game since then, and are an important device to gameplay. Some abilities and/or equipment has more than one Proof ability, such as the Ribbon, and is thus far more useful than any other single Proof ability available, though these types of abilities don't usually show up until the end of the game.

The following list entails all of the Proof abilities:
