Cameo Belt is an accessory in Final Fantasy XII that improves the wearer's chance of hitting enemies, by making the enemies unable to parry or block or evade the wearer's attacks. In the Zodiac versions, Cameo Belt also gives +3 to Magick.
In the original PlayStation 2 versions, the Cameo Belt can be bought for 9000 gil from Old Archades (before obtaining Treaty-Blade), and from Balfonheim Port. It also rarely (3%) drops from Archaeoaevis.
In the updated Zodiac versions, the Cameo Belt is not available from shops, but sells for 4500 gil. It is found in a treasure in Barheim Passage's Terminus No. 7 Adjunct (25% chance to appear but is always the Cameo Belt) and Subterra's Umbra - North (only 5% chance to appear, but is always the Cameo Belt), as well as in Trial Mode Stage 100 (with the Diamond Armlet equipped).
It very rarely drops from the Archaeoaevis (1%), but the enemy is much tougher in the Zodiac versions than it was in the original.
Cameo Belt ensures that the player's attacks hit, making it especially useful against enemies that block and parry a lot, such as Gabranth in the Trial Mode Stage 100 in the Zodiac versions, or the Fury optional boss. The wearer can still miss due to poor accuracy when blinded or when using bows and crossbows in bad weather.
