Paralyze (ability)

Paralyze, also known as Stun (スタン Sutan) and Threaten is a recurring spell and status effect which prohibits characters from taking action. It is different from Stop in that it does not last as long.

Final Fantasy
Paralysis prevents the afflicted unit from participating in battle. There is a chance of recovery at the end of each turn and the status does not last after battle. The spell Stun, also known as STUN in the Famicom release, is a level 6 Black Magic spell which almost always inflicts Paralysis on a single enemy, unless they are immune. It has a much higher success rate than Hold, a similar, lower level spell.

The spell can be bought at Crescent Lake and can be learnt by the Black Mage and Black Wizard job classes. In the Dawn of Souls and 20th Anniversary Edition releases it costs 20 MP to cast.

Final Fantasy II
Paralyze prevents the afflicted unit from participating in battle. There is a chance of recovery at the end of each round and does not last after battle. It can be removed by the spell Basuna at level 5 or higher. This is the only status effect that is mentioned in the game's Bestiary if a particular enemy is weak against it.

The spell Stun is a Black Magic spell which inflicts Paralyze on one or all enemies. The success rate increases with the spell's level. As with all spells, any character can learn Stun by having them use the Stun Tome (called the Stun Scroll in the Origins release). It was mistranslated as "Stone" in the J2e fan translation.

Final Fantasy III
Paralysis can be caused by the level 4 Black Magic spell Shade and Ramuh's white effect Spark. It is also inflicted by the weapons Ancient Sword and Earthen Bell.

Final Fantasy IV
The status Paralysis is inflicted by the summon Mindflayer and the magic Hold.

Final Fantasy V
Paralysis is caused by the Dark Arts ability Chaos Drive, and the Blue Magic spells Death Claw and Mind Blast.

Crisis Core -Final Fantasy VII-
Stun is a status effect that temporarily stops action.

Final Fantasy X
Threaten is a Special ability found in Auron's section of the Sphere Grid. It costs 12 MP to use. The Threaten status lasts until the caster's next turn. Shiva's Heavenly Strike also inflicts Threaten.

Final Fantasy XI
Paralyze is a White Magic, Enfeebling Magic spell that inflicts a status effect of the same name. The status effect paralyze can be gained in many other ways, including many different enemy abilities. The spell itself is relatively low level and can potentially last for minutes. While in effect a player may or may not be able to perform an action. Rather randomly, a player's turn may be negated with the simple notification that "______ is paralyzed." If a player was attempting to use an ability or item and is paralyzed, the ability will be subject to the recast timer as if it went off successfully or the item will be lost.
