Immunity abilities are support abilities that appear throughout the Final Fantasy series. Most of the time they are nameless, providing immunity to elements and status ailments. They are almost always provided by equipment, having no recurring terminology.
The customization system in Final Fantasy X provided a name for these support abilities: the "-proof" suffix. Elemental immunity is not present in early installments, with only elemental resistance being present.

Curiously, the Elemental Materia can also be linked with a non-elemental Materia for the Hidden effect. For status immunity, the wearer gains immunity to all statuses the linked Materia can inflict, whether or not the Materia has actually learned the respective spells yet; linking Added Effect with Transform gives immunity to both Mini and Toad, even if the Materia hasn't learned Toad yet.
List of Materia statuses:
- Contain: Petrify, Confuse, Berserk, Paralyze
- Destruct: Instant Death
- Mystify: Confuse, Berserk
- Poison: Poison
- Seal: Silence, Sleep
- Time: Slow, Stop
- Transform: Mini, Toad
- Choco/Mog: Stop
- Hades: Sleep, Poison, Confusion, Silence, Toad, Mini

Immunity to status and elements is obtained via the Junction system. Guardian Forces learn the Elem-Def and ST-Def abilities either naturally or via the Elem Guard and Status Guard items, and then stocked magic can be junctioned via these abilities to grant immunity to the elemental and status properties the spells possess. Most effects are straightforward, e.g. Fire spells having the Fire element for junctioning, but some magic spells are special, such as Ultima, that has all elemental properties.
Status immunity abilities appear under different names, and include Insomniac, Jelly, Antibody, Locomotion, Loudmouth, Bright Eyes, Clear Headed, and Body Temp. Body Temp protects from Heat and Freeze and Antibody also protects from Venom.
Equipping the corresponding immunity ability after the status effect has afflicted a character does not remove said status effect. The immunity abilities are learned from equipment pieces by accumulating AP in battles, but not every party member learns every immunity ability.
As status immunity is handled by the party's own support abilities, the elemental immunity is handled by the equipment pieces themselves.
Elemental proof abilities are upgraded forms of the abilities with the "Ward" suffix, stopping their respective element from inflicting damage to the wearer, instead of the 50% semi-resistance offered by the "Ward" abilities. They are still a step down from the abilities with the "Eater" suffix, which absorb their respective elements damage. The elemental proof abilities are spiritual upgrades of the elemental SOS Abilities, which function the same, but require the player to be in the HP Critical status for the effect to activate.
