Players can spend Premium Currency on cosmetics offered in the shop.
The Battle Pass has both free rewards (cosmetics, premium currency, and gameplay boosts) and paid rewards (cosmetics and premium currency only).
The Shop sells cosmetics for Premium Currency. Cosmetics give players even more options to customize the visual appearance of their characters. Nothing offered in the Shop grants a direct or indirect gameplay advantage. So, while many of these may look like powerful pieces of gear, they have no in-game stats.
