The Storm Staff is a staff in Final Fantasy XII. It is one of a set of three staves that improve elemental potency with similar stats, including the Flame Staff and Glacial Staff, this one increasing the Lightning element. In the original versions the three staves are activated with the same license and have identical stats and worths, however, in the Zodiac versions they are no longer equal, the Storm Staff being the middle of the three. For their elemental damage boosting properties, the staves remain useful till endgame, however, and are especially useful in the Zodiac versions where the damage cap has been lifted.
In the original version, its license costs 25 LP. In the Zodiac versions its license costs 30 LP and it can be used by the Black Mage.
Storm Staff is a weapon.
