Before you roll
Save your current Stand at D'Arby
Using an arrow awakens a new Stand and replaces the one you have equipped. If you want to keep your current Stand, store it first at D'Arby (Stand Storage) at the Docks. The official card says D'Arby can turn your Stand into a Stand Chip, and the Stand Chip card says the Stand you have equipped is lost for good when you use a chip. Save the one you care about before farming a new roll.
