Riot Games adds new in-game cosmetics in LoL, when the Christmas time gets closer in real life. This time they have presented the Winter Skins before a large patch coming in a couple of weeks. 

The first one is that of Diana. Next come Zoe, Zilean, Shaco, Swain, and Warwick. These champs haven't been blessed with Winter skins before. Those 6 skins are not the only addition, however: Warwick's going to get that Prestige skin, which looks even more stunning in action. Purple and green are the main colors of the winter theme.  Similar vibes have been injected in 2019's Sugar Rush collection. 

Abilities and animations have not been revealed for these skins at this time, but they should be expected to land on the League PBE in the coming days.
