Crystals are the premium currency of Granblue Fantasy. They can be used to purchase almost all of the same items available for real-world currency.
The biggest use for crystals is for performing Premium Draws to obtain new characters, weapons, and summons. There are also some useful purchases available in the Crystal shop, primarily expanding inventory space and adding weapon/summon stashes.
