The League of Legends patch 13.1 rolls out today

The 13.1 patch for League of Legends has released today (January 10), and brings with it a host of champion buffs and nerfs that are bound to have an impact on the esports scene.

League of Legends patch 13.1 champion and item changes

The first patch of the year was released on 5am GMT, and starts off the League of Legends 2023 season in earnest. From here on, Riot Games will return to releasing patches every two weeks in order to make alterations to the game's meta.

One of the more notable additions in today's patch is the mid-scope update for Jax. As lead champion designer August Browning noted on Twitter in December, the update is "on the smaller side," with his Relentless Assault and Empower being left unchanged.

The focus has instead been on Grandmaster’s Might, which has seen its damage reduced from 100/140/180 (plus 70% Ability Power) to 100-150 (plus 60% Ability Power). The spell has also been updated with a new active, the description for which reads: "Jax swings his lantern around him, dealing 150-300 (+100% AP) magic damage to nearby enemies. If he hits an enemy champion, he gains 10-40 (+.1 bonus AD) armor and magic resist, plus 14-22 (+.1 bonus AD) per champion hit for the next 8 seconds."

Additionally, the latest update means that Jax's Counterstrike has more scaling with Ability Power. The base damage has been increased from 55-155 to 55-175, which now scales with 100% Ability Power. However, the damage bonus per attack dodged has been reduced from 20% of total damage to 20% of base damage.

Jax isn't the only champion to be changed through the update. As Riot Games shared earlier this month, a number of underpeforming champions will be buffed through the patch - including AD Shaco, Jayce, Lissandra and Sion.

It isn't all buffs however - a handful of champions have been nerfed in today's patch - and it's bad news for top laners, with a number of top lane champions now being less effective following patch 13.1.

Aatrox is particularly notable among the nerfed champions. He has long dominated the professional scene, boasting among the highest pick-ban rates of any champion at tournaments throughout 2022. According to gol.gg, Aatrox saw a win rate of 54.5% at Worlds 2022, and so it will be interesting to see how this update affects his future standing. Following this nerf, it's entirely possible that we could see an entirely new meta in the top lane.

Other nerfed champions include Dr Mundo and Fiora, the third-most banned champion in the game. Support champion Yuumi has also been nerfed, perhaps due to the fact that she has the highest ban rate of any other support in the game, at 1354 (625/729).

We won't have long to wait to see how these champion changes will affect the League of Legends professional scene. The 2023 season has kicked off in earnest, starting with the Season Kickoff event taking place today. After that, it's just a few weeks to go before the LEC 2023 Winter Split, taking place from January 21 to January 26.
