Regen (status)

Regen (リジェネ, Rijene) is a recurring status that constantly restores HP at a set interval. Characters afflicted by Regen gradually recover HP over time, however, it has the exact opposite effect if the character is undead, where it gradually reduces one's HP, as if poisoned. This also applies to enemies, meaning that casting Regen on an Undead will cause it to lose HP. In other cases, Regen does not work at all against an Undead. Regen is the opposite of Seizure. There is very few methods of applying Regen to a character.

Final Fantasy IV
Regen can only be achieved through Fusoya's command Regen, which paralyzes Fusoya while he generates a constant Regen effect on the party for a period of time.

Final Fantasy V
Regen is achieved through the spell Regen, the accessory Protect Ring, or through the Mix ability Water of Life (through combining a Potion and Hi-Potion). There is no visible indication of the status in effect, except for the occasional healing.

Final Fantasy VI
Regen status is achieved through the spell Regen, or by a character equipping the Angel Ring or Miracle Shoes Relics.

Final Fantasy VII
Regen can be first used as the third advancement of the Restore materia. This is the only way of granting the status to the party in the game. A character under Regen status will glow an orange color until the status wears off.

Unlike most games with Regen status, which restore a little HP every so often, Regen in this game causes HP to continuously rise until the effects wear off. This effectively negates weaker enemy attacks, as the character will regenerate too fast for the damage to register.

Final Fantasy VIII
Regen can only be achieved through the spell Regen or through Quistis Trepe's Limit Break, Mighty Guard.

Final Fantasy IX
The spell Regen, the Flair ability Aura, the Dragon ability '''Reis's Wind, and ability Auto-Regen are the only ways for the party to gain Regen status.

Final Fantasy X
The spell Regen, the item Healing Spring, the Mix abilities Super Mighty G and Hyper Mighty G, and the auto-abilities SOS Regen and Auto-Regen grants Regen status to party members.

Final Fantasy X-2
Regen, Auto-Regen, SOS Regen, and Healing Spring all return to bestow Regen status. The accessories Regen Bangle and Recovery Bangle both grant Regen (Regen Bangle granting SOS Regen and Recovery Bangle Auto-Regen). The Item Reels ability Mighty Guard+ grants Regen to the party (as well as Shell and Protect), while Yuna's Mascot abilities Moogle Regen and Moogle Regenja grant Regen as well as Haste to one character or the party, respectively. Floral Fallal's ability White Honey bestows Regen as well.

Final Fantasy XII
Regen status is achieved through casting the spell Regen, equipping the Ring of Renewal accessory, or equipping the Healing Rod. The status is also granted if a character is wearing the Renewing Morion light armor.

Final Fantasy XII: Revenant Wings
The only player spell that grants Regen is Basch's Regenga. Penelo's Protective Armlet accessory bestows Regen upon every member of her team.

Final Fantasy Tactics Advance
Auto-Regen is available to Hunters and Snipers as Reaction Abilities. A Defender's Aura skill bestows Regen along with Auto-Life. The Summoner's summon, Kirin, bestows Regen in an area.

Final Fantasy Tactics A2: Grimoire of the Rift
Regen is a buff that gives the targeted unit 1/10th of its max HP (rounded down). In addition to being a reaction ability for Hunters and Snipers, it is also a clan benefit that can be chosen before each battle upon earning the clan title "Journeymen", and there are also the stronger versions of this Clan Privilege called Regenra and Regenegra. It can be learned as an action ability by many characters, but often isn't called Regen. Notable examples include Hurdy, who can learn the skill Angelsong from the Hurdy-Gurdy instrument that casts Regen on the target, and Adelle, who can use the skill Adelaide as a Heritor to cast Regen on the target as well.

Dissidia Final Fantasy
Regen is a status effect shared by all characters when entering EX Mode. It can also raise Bravery over time during EX Mode if the "Brave Regen" ability is equipped.

It is also a story mode skill that recovers 5% of the character's total HP whenever his Home Area changes. It continues over all the levels of the story.
