This year's Christmas skins are—Ambitious Elf Jinx, Santa Draven, and Snow Fawn Poppy
The skins are Ambitious Elf Jinx, Snow Fawn Poppy, and Santa Draven, and although we were hoping for Kandy Kayn, they're still fine additions to the League holiday skin arsenal. The price of each skin is currently unknown, but we'll likely know more then the skins reach the PBE this week.
Last year, the event brought with it a new game mode, a custom wintery Summoner's Rift, event crafting, and more. Hopefully, this year's Snowdown will stand up to that legacy of awesome new goodies.
