Nirvana

Nirvana (ニルヴァナ) is a recurring weapon in the Final Fantasy series. It is usually the most powerful staff in the games it appears in and is mostly used by Summoners or White Mages.

Final Fantasy IV
Nirvana is a Staff exclusive to the Game Boy Advance version of Final Fantasy IV, and can only be equipped by Porom. It provides +80 Attack, 40 Accuracy, +15 to Stamina and Spirit, and casts Reflect when used as an item. It is found in the Lunar Ruins.

Final Fantasy IV: The After Years
Nirvana is a weapon that can only be accessed via hacking, and provided 80 Attack as well as several stat boosts. It would have cast Reflect when used as an item, and would have been used by several characters.

Final Fantasy X
The Nirvana is Yuna's Celestial Weapon, and can be obtained at Monster Arena in the Calm Lands. It requires the Moon Crest and Sigil to attain its maximum power. At maximum power, its abilities are Break Damage Limit, Triple Overdrive, Double AP, and 1 MP cost. It also allows the aeon Valefor to break the 9,999 damage limit once activated. Using the Moon Crest or Moon Sigil raises the damage limit to around 30,000, while using both Key Items will raise the damage limit to 99,999.

Final Fantasy X-2
Yuna wields the Nirvana when she is in her Black Mage Dressphere.

Final Fantasy XI
The Nirvana is the Summoner's Mythic Weapon. It reduces avatar perpetuation cost by four (exceeding even Bahamut's Staff), increases Magical Attack power of avatars by a significant amount, and features the unique Garland of Bliss Weapon skill. Because of these factors, and because the comparable Relic Weapon upgrade for Summoners, the Claustrum, is arguably the worst in the game, Nirvana is considered one of the few actually sensible Mythic Weapon upgrades.

Final Fantasy XII: Revenant Wings
The Nirvana is one of Penelo's strongest staves and can only be crafted in the Sky Saloon.

Final Fantasy XIII
The Nirvana is a final tier rod weapon for Oerba Dia Vanille, upgraded from a maxed second tier weapon using a Trapezohedron. Whilst their passive and synthesized abilities vary, all Nirvanas add one additional ATB gauge segment.

Final Fantasy Tactics Advance
The Nirvana is a powerful staff that can teach Full-Life to White Mages, Holy to Bishops, and Phoenix to Summoners.

Final Fantasy Tactics A2: Grimoire of the Rift
The Nirvana reappears at the Ultimate Staff. It adds 34 to the Attack stat and 10 to the Resistance stat. It's elemental property is Holy. Nirvana can still teach Arise to White Mages, Holy to Bishops, and Phoenix to Summoners. In order to buy it at any shop, you need to send a Lightwing Crystal, a Mahberry and a Crusader Tonic to the Bazaar. You can only buy it once for 8800 gil. Afterwords, you'll have to re-send the loot necessary back to the Bazaar.

Dissidia Final Fantasy
The Nirvana is the strongest staff in the game and increases EX Mode duration by 40%.

Etymology
Nirvana is a religious term used to describe the ultimate goal of the Buddhist religion (a similar concept exists in Hindu). It refers to the final level of consciousness denoted by perfect balance, knowledge, and peace which only pure souls with good karma may reach, and it is thus attained via reincarnation.
