Gillionaire, also known as Millionaire (取得ギルアップ, Shutoku Giru Appu?), Gil Farmer, Gil Plus, Gilfinder, and Smart Riches, is a recurring ability in the series that lets the player earn more gil from battles.
The Gil Band is an accessory that multiplies the amount of money the party earns by 1.5. It is initially equipped on Edward Chris von Muir in Edward's Tale. In the Crystals, a Gold Tail can be traded for a Gil Bandv2, which doubles the amount of money earned.
Although it is never mentioned in-game, the Cat-Ear Hood headgear provides the Gillionaire ability which doubles the amount of gil the party earns from enemies. It can be obtained by betting an Impartisan in the Dragon's Neck Coliseum and can only be equipped by Relm.
The Gil Plus Materia boosts the amount of gil earned from battles. Due to a bug, Level 1 will never produce the 1.5x amount that it is supposed to, and will always double the amount of gil earned from battles as though it were mastered. The effect is not stackable. Gil Plus can be purchased in Gold Saucer's Wonder Square for 1,000 GP.
Gillionaire is an ability that can be found or customized on a weapon. It requires using 30 Designer Wallet items to customize. Rikku's Celestial Weapon, Godhand, has this ability when fully-powered. The effect can not be stacked, in case various characters are equipped with Gillionarie ability.
Gillionaire is an ability found on the Lady Luck dressphere. It takes 100 AP to learn, and it can be learned after mastering Double EXP. It can also be accessed via the Horn of Plenty Garment Grid by passing through the red gate on the grid. The ability is stackable.
Gilfinder is a Thief job trait that increases the amount of gil enemies drop, usually by 150%. The ability is learned at level 5, and is enhanced by Assassin's Culotte, Palmer's Bangles and Andvaranauts.
The Collector's Catalog accessory, with Gilfinder II for +50% Gil, can be won from Serendipity Chocobo Racing. Together with other ingredients, this can be upgraded to a Durable Collector's Catalog, with Gilfinder MAX for +100% Gil, at Chocolina, after the story's conclusion. Level 1 Chunerpeton recruitable monsters have the Gilfinder II ability. Gilfinder gives +30% Gil. Gillionaire bonuses combine for a net maximum of three and a half times as much gil. Item Collector and Item Scavenger bonuses to the drop rate of rare and common items, on the other hand, have high individual bonuses, and only the highest value is used.
The Beckoning Cat accessory increases the gil earned from battle by 20%. When three pieces of Gold equipment are worn, they activate the Glorious Gold combination, raising the gil earned in battle by 50%. Certain Calendar Bonuses increase the gil won, from 10% up to 100% depending on the level of the bonus. In Dissidia 012 only, the Qu'bia Tail accessory found only in the Labyrinth increases gil earned by 100%.
More Money is the specialty support ability of Merchants. It lets the characters earn 1.5 times more money than normal.
