Here are the League Patch 13.7 patch notes

With playoffs looming on the horizon or already in full flight around the League of Legends world, Riot Games is looking ahead to the next major event, the 2023 Mid-Season Invitational, and making a host of champion changes in League Patch 13.7 as the run-in begins.

League Patch 13.7 release date

The next update of 2023 will roll out on Wednesday, April 5, 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 are the key patch rollout times for some of 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.

What’s coming in League Patch 13.7?

Buffs and nerfs galore as MSI looms

With the first premier League event of the year just around the corner, it’s all hands on deck to get the season 13 metagame heading in the right direction.

“We’re two patches away from MSI,” top dev Phroxzon said on March 27, before adding League’s dev team is liking how the meta is shaping. Despite that, they’ve still got some tweaks they want to make.

That includes changes for playmaking mage Katarina, another lift for Azir, and careful boosts for several fringe champions. The jungle’s S-tier picks⁠—Olaf, Sejuani, Vi, Lee Sin, and Kha’Zix⁠—are all in the firing line, as are several bot lane powerhouses like AD carry monster Zeri and hook-happy Thresh.

Rammus and Veigar will also have their win rates fiddled with.

It’s raining cat and dog skins in League

Four champions are getting cutesy cat and dog outfits in the 13.7 update, including Kindred, Kled, Yuumi, and Nidalee. The first three are dog-themed while the Bestial Huntress is—fittingly—getting a kitty cosmetic. All four characters will also have between six and eight chromas available.

Here are all the new skins coming in this patch:

Woof and Lamb Kindred (1,350 RP)
Kibble-Head Kled (1,350 RP)
Kittalee Nidalee (1,350 RP)
Shiba Yuumi (1,350 RP)

These cat and dog skins are set to go live during the League Patch 13.7 cycle.

Here are all the official patch notes for the April 5 update.
