Going around in Teyvat one can encounter these strange fans that are activated using anemo characters. It makes sense that once one blows wind towards them, these fans start turning and produce their own wind lifting or similar effects. You can use these wind energies to reach places otherwise impossible to reach.
Around Teyvat you can find many interactable objects, some of them are these strange looking torches. To activate these torches one just needs to use a fire character and use a fire ability enarby. Many times the torches will be on a timer so using a ranged fire character is often wise. Amber fits this role perfectly.
