League of Legends Patch 13.1 patch notes | All buffs, nerfs, and changes coming in League Patch 13.1

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.

First up is Patch 13.1, which will get the 2023 League season started in earnest. As usual, there’s champion changes, item adjustments, and veteran Summoner’s Rift combatant Jax is getting a mid-scope update to modernize his ability kit and put him right back in the metagame.

On top of the gameplay changes, Riot Games is expected to release all-new variant skins across the first January patch cycle.

Here’s everything you need to know about League Patch 13.1.

League patch 13.1 release date

The first update of 2023 will roll out on Tuesday, Jan. 10, according to Riot’s patch schedule. As per usual, the patch will roll out worldwide across the day, starting in Australia at around 10am (AEDT).

Here’s the patch rollout times for the major League servers:

3am PT (NA)
5am GMT (EU West)
3am CET (EU North East)
8am KR (Korea)

There will be several hours of downtime once the patch begins. Matchmaking and competitive queues will be disabled across all League servers three hours before the update is officially deployed and set live.

Buckle up for another year of grinding, Summoners: the next League ranked season is officially slated to begin on Tuesday, Jan. 10. This will go 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.

According to Riot Phlox, the new-look Jax update will arrive on Summoner’s Rift on Tuesday, Jan. 10, all packaged up with the 13.1 champion changes.

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