@Riot Warring Kingdoms Katarina

As a Katarina one trick main, I was not able to have Earn the golden warring kingdoms katarina chroma during the Chinese lunar revel due to my chronic depression during the time. Are there any ways to optain this chroma, will it ever be avaliable again besides obtaining it from Gemstones? Acquiring gemstones are quite rare for me..... [sg-soraka]
