The Carmagnole is a mid-ranked mystic armor in Final Fantasy XII that boosts the wearer's Defense by 37 (Zodiac) or 29 (original) and Magick Power by 7. In the Zodiac versions, it also gives 40 MP.
In the original PlayStation 2 version, the Carmagnole is sold for 5,900 gil Mosphoran Highwaste after defeating Judge Bergan, and in the Phon Coast's Hunter's Camp. It is rarely poached from the Serpent, and is the reward for the hunt for the Mindflayer.
In the updated Zodiac versions, the Carmagnole is sold for 5,900 gil in Phon Coast's Hunter's Camp and in Archades. It is found as a treasure in Phon Coast's The Hakawea Shore (70% chance to appear, 50% chance for gil, 50% chance the item treasure is the Carmagnole without the Diamond Armlet equipped), and Tchita Uplands' Oliphzak Rise (35% chance to appear, 70% chance for gil, 50% chance the item treasure is the Carmagnole without the Diamond Armlet equipped). It is still the rare poach from the Serpent and the reward for the hunt for the Mindflayer.
Carmagnole is a mid-ranked mystic armor, giving 37 or 29 Defense, and 7 Magick Power, as well as 40 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.
In the Zodiac versions, White Mage, Red Battlemage, Black Mage, and Bushi can equip it, and so the Carmagnole is only useful to buy 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.
