Here are the League Patch 13.1 patch notes

Finally, League of Legends season 13 is here. After a short break for the Christmas and New Year’s holidays, the Riot Games developers are back at work tweaking and massaging the ever-changing League meta with fortnightly patches.

**Biggest updates & changes in League patch 13.1**

New ranked season begins

Buckle up for another year of grinding, Summoners: the next League ranked season has officially started on Tuesday, Jan. 10. The new competitive grind went live at the same time that Patch 13.1 hits servers.

This time around, the ranked season will be sliced right down the middle, with players contesting two splits instead of one long-running ladder. There will be new ranks and rewards for both these splits throughout the year.

Jax’s mid-scope update is here

After initially teasing a mid-scope update for Jax (and, at the time, Rell), the Riot Games dev team has finally let players get their hands on the Grandmaster at Arms’ changes. The new-look Jax update has arrived on Summoner’s Rift, all packaged up with the 13.1 champion changes.

Four champions, four items up for buffs

The Riot Games dev team is hoping to expand itemization for mages in 2023, and this new project is getting started in the very first update of the new year. Archangel’s Staff, Horizon Focus, Rod of Ages, and Winter’s Approach are all due for varying buffs.

Those boosted items are joined by four champions in the green column, including Shaco, who is getting some attack damage love.

Yuumi, Aatrox lead nerf list

League players are ringing in celebrations when the first update of the 2023 season—according to Riot Phlox, who shared the 13.1 patch preview on Twitter, infamous floating cat Yuumi was a main target for Season 13 nerfs.

She is joined on the chopping block by pro play power pick Aatrox, as well as Dr. Mundo, Fiora, new champion K’Sante, and plenty more.

New Mythmaker, Lunar skins

League players are getting spoiled in the year’s first update, with a dozen skins hitting the in-game shopfront, including a new Prestige Porcelain skin for Lissandra, six new Mythmaker variants, and five Lunar upgrades.

Here are all the skins packed into League Patch 13.1:

Lunar Empress Ashe (1,350 RP)
Mythmaker Galio (1,350 RP)
Mythmaker Garen (1,350 RP)
Mythmaker Irelia (1,820 RP)
Mythmaker Zyra (1,350 RP)
Mythmaker Sivir (1,350 RP)

Prestige Mythmaker Sivir (2,000 Lunar Revel 2023 tokens)
Prestige Porcelain Lissandra (2,000 Lunar Revel 2023 tokens)
Lunar Guardian Kha’Zix (1,350 RP)
Lunar Guardian Malphite (1,350 RP)
Lunar Empress Qiyana (1,350 RP)
Lunar Emperor Thresh (1,350 RP)

These skins went live at the same time as the League 13.1 update.
