The Gold Hairpin is a mid to high-ranked mystic headgear in Final Fantasy XII that boosts the wearer's Magick Resist by 47, Magick Power by 7, and—unusually for a mystic armor piece—Vitality by 8. In the Zodiac versions, it also gives 80 MP.
In the original PlayStation 2 version, the Gold Hairpin is sold for 9,300 gil in Balfonheim Port. It is also found as a treasure in Henne Mines' Phase 2 Dig (55% chance to appear, 28% chance for gil, 50% chance the item treasure is the Gold Hairpin without the Diamond Armlet equipped ), and Pharos - First Ascent's Wellspring Labyrinth (south; 65% chance to appear, 50% chance for gil, 50% chance the item treasure is the Gold Hairpin without the Diamond Armlet equipped ).
In the updated Zodiac versions, the Gold Hairpin is not sold in shops, but sells for 4,650 gil. It is a treasure in Cerobi Steppe's The Terraced Bank (20% chance to appear, 20% chance for gil, 5% chance the item treasure is the Gold Hairpin with the Diamond Armlet equipped), and in Great Crystal's Bhrum Pis Pratii (always appears). It is also now a rare steal from Mythril Golem in Trial Mode Stage 38.
Gold Hairpin is a mid to high-ranked mystic hat, giving 47 Magick Resist, 7 Magick Power, and 8 Vitality, as well as 80 MP in the Zodiac versions. Mystic armor offer magick-related bonuses that affect all types of magickal actions, from casting black magick to damage an enemy, to casting white magick to heal the party. Magick Power is also a factor when determining damage dealt by katana, staves, and maces. The Vitality bonus can be good for both spellcasters (as it lengthens buff duration and increases the odds of inflicting enemies with status ailments) and those who use axes, hammers, and hand-bombs (Vitality counts for their damage calculation), however, in the Zodiac versions, the Time Battlemage and Foebreaker boards do not unlock mystic armor. Gold Hairpin is the best mystic hat that gives Vitality, but other hats surpass it in other stats.
In the Zodiac versions, White Mage, Red Battlemage, Black Mage, and Bushi can equip it, and so the Gold Hairpin is only useful to look for if the player has chosen any of these License Boards for their party. In The Zodiac Age versions, after fighting Belias the player can choose two License Boards per party member; it is usually a good idea to pair jobs that use two different types of armor for versatility.
The Gold Hairpin is available when the route to Nabreus Deadlands is open, from whose Dead Bones the player could procure the vastly superior Golden Skullcap, the second-best mystic hat in the game. It is optional to visit, however, and thus the party should prepare to face tough enemies while there.
The golden hairpin is an important item in the Chinese tale, A Golden Hairpin Saves Li Shimian's Life.
