Jade Collar is an accessory in Final Fantasy XII that improves the wearer's chance of avoiding attacks by enabling parrying and increasing evasion by 30%. In the Zodiac versions, Jade Collar also gives +3 to Speed.
In the original PlayStation 2 versions, the Jade Collar can be bought for 3300 gil from Eruyt Village. It can also be found in a treasure on the Giza Plains during the Rains on Gizas South Bank (the southern dead-end bit; 35% to appear, 60% chance for gil, 50% chance the item treasure is a Jade Collar without the Diamond Armlet ).
In the updated Zodiac versions, the Jade Collar is not available from shops but sells for 1650 gil. It is found in a treasure in Garamsythe Waterway's drained No. 3 Cloaca Spur (always appears), Subterra's Umbra - South (70% chance to appear, 60% chance for gil, 50% chance the item treasure is Jade Collar without the Diamond Armlet), and Necrohol of Nabudis's Hall of Slumbering Might (always appears), as well as on the Trial Mode Stage 100 with the Diamond Armlet equipped. It is also an uncommon steal from Hell Wyrm in Trial Mode Stage 87.
Jade Collar allows the wearer to sometimes avoid enemy attacks by parrying them. When the character takes a hit, the game checks against the equipped shield first, then the equipped weapon, and finally the parry chance from the collar. If all checks fail, the hit connects. The menu misleadingly just shows one Evasion stat that simply sums all different types of evasion.
Jade is an ornamental rock. The term jade is applied to two different metamorphic rocks that are made up of different silicate minerals. Nephrite can be found in a creamy white form (known in China as "mutton fat" jade) as well as in a variety of greens, whereas jadeite shows more colour variations, including blue, lavender-mauve, pink, and emerald-green. Of the two, jadeite is rarer. Translucent emerald-green jadeite is the most prized variety.
