The Leisure Device: Rhythmic Sprinter is an interesting item that players can get in Genshin Impact. It can be purchased from the Realm Depot in the Serenitea Teapot for 300 Realm Currency. Realm Currency generates over time and can be collected from Tubby outside the main structure in your Serenitea Realm.
The Rhythmic Sprinter is designed to help players who were holding races in their realms by giving them a way to set up course and time the runs.
How to use the Rhythmic Sprinter
After you purchase the Rhythmic Sprinter, go into Edit mode and put down both the Activation Panel and the Destination Ring. After that, you’ll need to go into Move Mode where you will be able to move the two devices independently from each other. You cannot, however, place the Activation Panel in one area, and the Destination Ring in another area, they must both be in the same area of the Realm.
