How do you access the rewards if you bought on steam? Are they just in the cosmetics tab?
It depends on what exactly you have in mind;
- The Cosmetic Coins will be shown in the store when that has been implemented.
- The Juvenile Skullen is available from the Cosmetics tab (the default keybind is K).
- The Ardent Gladiator badge is available on Last Epoch's official forum.
- The soundtrack will be available in-or-around release. It's being worked on alongside the game.
