Upon subscribing to Untapped.gg Premium for Storybook Brawl, you will be asked to link your Steam account to your Untapped.gg account.
Once you’ve done that, the Untapped.gg Hero Frame will be automatically granted to you in the game. To claim a costume, choose one of the available costumes above. New Costumes will be added to the pool regularly.
Every 90 days that you remain subscribed, you will receive an updated Hero Frame and can unlock a new Costume of your choice from the available selection.
