The Black Garb is a mid-ranked mystic armor in Final Fantasy XII that boosts the wearer's Defense by 33 (Zodiac) or 27 (original), Magick Power by 6, and Speed by 3. In the Zodiac versions, it also gives 38 MP. It has lower offensive stats than the preceding Sorcerer's Habit, but offers a Speed boost whereas most mystic gear don't. Speed has minimal effect on Charge Time, but does count in the damage calculations for bows, ninja swords, and daggers. However, in the Zodiac versions, Archer and Shikari boards don't unlock mystic gear.
In the original PlayStation 2 version, the Black Garb is sold for 4,900 gil Rabanastre and Nalbina Fortress after defeating Judge Bergan. It is found as a treasure in Phon Coast's Cape Uahuk (northwest; 40% chance to appear, 80% chance for gil, 50% chance the item treasure is the Black Garb without the Diamond Armlet equipped ).
The Black Garb is rarely stolen from the Pumpkin Head, and is made in the bazaar set "Ninja Garb" by selling four Fine Wools (from some gator-type enemies, e.g. Baritine Croc in Paramina Rift), two Tanned Tyrant Hides (from Archaeosaur), and five Fire Magicites (from various enemies, e.g. Worgen).
In the updated Zodiac versions, the Black Garb is sold for 4,900 gil in Mosphoran Highwaste after defeating Judge Bergan, and in Phon Coast. It is found as a treasure in Mosphoran Highwaste's Trail of Sky-flung Stone (75% chance to appear, 40% chance for gil, 50% chance the item treasure is the Black Garb without the Diamond Armlet equipped), and Northern Skirts (70% chance to appear, 40% chance for gil, 50% chance the item treasure is the Black Garb without the Diamond Armlet equipped), as well as the Trial Mode Stage 94 with the Diamond Armlet equipped.
It is still rarely stolen from the Pumpkin Head and is made in the bazaar with the same item requirements as before.
Black Garb is a mid-ranked mystic armor, giving 33 or 27 Defense depending on version, 6 Magick Power, and 3 Speed, as well as 38 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 Speed boost from the Black Garb has minimal effect on the wearer's Charge Time and affects damage for bows, ninja swords, and daggers. In the Zodiac versions, however, the boards that use these weapons do not unlock mystic armor.
In the Zodiac versions, White Mage, Red Battlemage, Black Mage, and Bushi can equip it, and so the Black Garb 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.
The Black Garb offers less Magick Power and MP than the preceding Sorcerer's Habit, and the Speed boost is likely not relevant enough to offset this, and so the player may not plan to upgrade via the shop if they have the Sorcerer's Hat already.
