Riot tweeted out two images on Sunday, the first showing Urgot using his chains over the words "in 5 days we break them" and the second declaring that the 2020 season starts on January 10.
Season 10 will start with a soft reset of ranked, with brand-new ranks determined based on performance throughout the pre-season as well as positioning matches. Much like in season 9, you'' ll get a provisionary rank after your very first match of the season and just after 8 matches will it become noticeable.
The first League of Legends patch for 2020 will present on January 8, two days before season 10 starts, and will bring with it new juggernaut Sett, a previous pit fighter according to his bio. The Mecha Kingdom skins ought to be rolling out quickly too.
A cinematic trailer is standard for these things, and that picture of Urgot'' s chains might well be a tease for it.
