The Excalibur is found at the Great Crystal in Giruvegan
Countless weapons are hidden all about the deepest reaches of "Final Fantasy XII," but one sword stands out. The Excalibur carries a legendary name and is easily one of the strongest weapons in the game, boasting an incredible attack power (128). The sword itself is found at the Great Crystal in Giruvegan. It can only be attained if you have the Diamond Armlet, which is found late in the game in the Dalmasca Estersand.
