TFT celebrates Year of the Snake
In addition to posting about these patch notes, Riot Games mentioned the 2025 Lunar Festival event. This year sees the return of the Festival of Beasts – it’s the mid-set of TFT Fates from September 2020!

Now, in 2025, players can look forward to a new roster of Chibis and Little Legends. Chibis include Mythmaker Zoe and Prestige Porcelain Ezreal. Meanwhile, Snek is the game’s newest Little Legend. Don’t forget about the new Lunar Festival Pass, either. This year’s iteration of it includes Chibi Seraphine and Lantern Snek.
