Orrachea Armlet is an accessory in Final Fantasy XII that gives the user +25 HP. In the Zodiac versions, it also gives +1 to Defense and Magick Resist. Orrachea Armlet is the first accessory the player gets.
In the original PlayStation 2 versions, the armlet can be bought from Giza Plains' nomad village during the dry for 250 gil. Vaan gets one for free from Tomaj in Rabanastre's Sandsea pub after looking at the hunt board where Tomaj explains the hunt system.
In the updated Zodiac versions, the armlet can be bought from Dalmasca Estersand's shop for 250 gil after receiving the Treaty-Blade, and it is a treasure in Dalmasca Westersand's Shimmering Horizons (always appears, but the treasure can be looted just once), the Royal Palace of Rabanastre's Lower Halls (chest always appears), in the Nalbina Dungeons' Confiscatory (chest always appears), and in Pharos - Subterra's Penumbra - North (70% chance to appear, 80% chance for gil, 50% chance the item is Orrachea Armlet without Diamond Armlet equipped). However, these methods are all unnecessary as the player still gets a free one at the start from Tomaj by listening to his Hunt tutorial at the Sandsea.
Orrachea Armlet is the starter accessory that merely gives a small boost to the wearer's HP. It is still worth unlocking on the License Board and wearing until the player can replace it with something better.
