Additionally, you need to open the third-party software every time you launch League of Legends, which may affect your PC’s performance. Other players will not be able to see your custom skins. However, most of these modifications are only local to your machine. They can modify the champion textures and other aspects of the user interface like the HUD and even the map.
Usually, to use these custom skins, you have to use third-party software like LCS-Manager and Fantome. Custom skins are basically champion skins that are not officially created or supported by Riot Games.
