Critical ability

Critical abilities, also known as SOS abilities, are a set of recurring abilities in the series. First appearing as SOS Shell in Final Fantasy V, critical abilities have grown to include just about all of the positive status effectes, and are either only active so long as the user is in Critical, or trigger when the character falls into critical health. The critical ability usually cannot be dispelled while active, and will automatically reapply should the character be KO'ed and revived back into Critical. The moment the user is restored to above their Critical HP limit, the ability will wear off.
The following is a list of critical abilities that have appeared throughout the series:
* Critical: Shell (aka Magic Shell) - Automatically puts the user in Shell status.
* Critical: Protect - Automatically puts the user in Protect status.
* Critical: Haste/Last Haste - Automatically puts the user in Haste status.
* Critical: Wall - Automatically puts the user in Protect and Shell status.
* Critical: Reflect - Automatically puts the user in Reflect status.
* Critical: Regen - Automatically puts the user in Regen status.
* Critical: NulBlaze - Automatically puts the user in NulBlaze status.
* Critical: NulFrost - Automatically puts the user in NulFrost status.
* Critical: NulShock - Automatically puts the user in NulShock status.
* Critical: NulTide - Automatically puts the user in NulTide status.
* Critical: Overdrive - Increases Overdrive gauge gain.
* Critical: Spellspring - Reduces cost of spells and techniques to 0.
* SOS Critical - Always deal critical hits.
* SOS ???? - As long as the user is in Critical, all healing items and spells heal for 9999 and all damage attacks, spells, and items will deal 9999 per hit.
While the following aren't named "Critical", they still follow the same format:
* Adrenaline - Doubles attack.
* Last Stand - Doubles defense.
* Spellbreaker - Doubles magic.
* Chivalry - Increases Attack and Magic.
* Gallantry - Increases Defense and Magic Defense.
* Restore HP/Critical: Recover HP - Regains half of Max HP/HP if character survives an attack while in Critical.
* Last Berserk - Automatically puts the user in Berserk status.
* Critical: Recover MP - Regains MP.
* Critical: Quicken - Can attack quicker.
* Critical: Vanish - Automatically puts the user in Vanish status.
* Critical: Evasion - Increases Evasion.

Magic Shell (also called Magiwall or Barrier) is the Level 1 ability of the Mystic Knight class. It requires 10 ABP to learn. When equipped, or if the user is a Mystic Knight (or a Freelancer with Mystic Knight mastered), they will automatically receive the effects of Shell when they reach critical HP.

The Barrier Ring cast Shell while the Mythril Glove casts Protect on the user once they enter Critical status. The Princess Ring, a female-exclusive relic, casts both Protect and Shell when the user is Critical. There is a dummied ability that cast Reflect when the user came under the Critical status. These abilities will only activate once per battle.

There are numerous SOS abilities. The SOS Overdrive ability is an auto-ability for weapons. It charges the Overdrive gauge at double the rate when the character is HP Critical. It can be customized to a weapon with Gambler's Spirit x20.
The SOS abilities for armor grant a buff to the user. Each of the four elements has an SOS ability which nullifies it with the respective Nul- status. The SOS NulBlaze auto-ability grants the user the NulBlaze status, granting immunity to the Fire-element when HP Critical, and can be customized to an armor with Bomb Core x1. The SOS NulShock auto-ability grants the user the NulShock status, granting immunity to the Lightning-element when HP Critical, and can be customized to an armor with Lightning Marble x1.

The SOS NulFrost auto-ability grants the user the NulFrost status, granting immunity to the Ice element when HP Critical, and can be customized to an armor with Arctic Wind x1.
The remainder of the SOS abilities for armor are predecessors of a number of the abilities with an "Auto-" prefix. SOS Shell grants Shell when HP Critical, and can be customized to an armor with Lunar Curtain x8. SOS Protect grants Protect when HP Critical, and can be customized to an armor with Light Curtain x8. SOS Reflect grants Reflect when HP Critical, and can be customized to an armor with Star Curtain x8.

It remains with the player after they have left the Critical status, but becomes susceptible to Dispel. It can be customized to an an armor with Healing Spring x12. Customizing SOS Regen to armor is part of a gil trick involving Kottos at the Monster Arena.

=== Final Fantasy Tactics ===
Critical: Recover HP (also called HP Restore) is a reaction ability the Monk class learns for 500 JP. When a unit equipped with this ability suffers from critical loss of HP, the unit's health will be replenished automatically.
Critical: Quick is a reaction ability the Time Mage class learns for 700 JP. When a character receives damage that reduces his/her HP to critical level, their AT will be elevated into the next position for immediate turn. This ability is the basis of the Quickening glitch, which allows player characters to act infinitely.
MP Restore is a reaction ability the Summoner class learns for 400 JP. If this unit is attacked and put into a critical state, MP Restore will restore their MP.
=== Final Fantasy Tactics Advance ===
Last Berserk is learned from the Defender job for 300 AP, while Last Haste is learned for 300 AP from the Beastmaster, Ninja, and Mog Knight classes. Last Quicken is also learned for 300 AP, from the Time Mage.

The Back to the Wall ability increases the chance of landing critical hits by 50% when the character is at critical HP, while Cat Nip increases the chance by 50% when the opponent has enough Bravery to kill the character in one hit.
The Rebellious Soul carries the Bonecrusher ability, which increases the character's Bravery by 20% of their max HP when they enter critical health. In Dissidia 012, the Fury of Qu'bia accessory found only in the Labyrinth carries the same ability.
