Riot Games is known for neglecting champions not only when it comes to balancing and making them relevant in the current meta, but also in the skins department. According to the community-made document created to help keep tck of champions always left out from the new skins section, two League of Legends champions have just celebted their second full year without a new skin.
A previous member of 1000 Day Skin Club, Kalista has now spent 732 days without getting a new skin. The last skin Kalista was lucky enough to receive was the Mauder Kalista with Patch 11.1. Aside from that, Kalista only has four more skins—default Kalista, Blood Moon Kalista, Championship Kalista, and SKT T1 Kalista.
