With the Mid-Season Invitation pro tournament just around the corner, Riot is rolling out a fresh League of Legends patch, 13.7, to help define the meta in time for the competition.

Azir will get a much-needed buff, while other powerhouse champions like Veigar and Zeri will get slight tweaks to their kits and damage numbers. Some Jungle champions like Graves, Sejuani and Kha'Zix have also had some champion adjustments to improve their viability in the Jungle.

Here are the early release patch 13.7 notes for League of Legends!

When will LoL patch 13.7 come out?

According to Riot Games' official patch schedule, the patch 13.7 release date will be Wednesday, April 5. The patch will be rolled out across the day - here are the critical patch rollout times for all major League of Legends servers worldwide.

  • 3AM PT (NA)
  • 5AM BST (EU West)
  • 3AM CET (EU North East)

As with all patch releases, there will be several hours of downtime while the patch is rolled out. Matchmaking and competitive queues will be disabled before the update is made live.

What's new with League of Legends Patch 13.7?

Some heroes getting buffs will include Jungle champions Olaf, Sejuani, Lee Sin, and Kha'Zix. There will be some other champion nerfs.

There are no significant updates in the LoL patch 13.7, as Milio the Gentle Flame has only just arrived on the scene. He has seen some success in his games, with a positive win rate of 51.58% so far. Only time will tell if this success continues in ranked matches.

Most of the champions released in 2022 were characters with high skill ceilings, so Riot is attempting to be more approachable and beginner-friendly with their releases this year, as seen with the Yuumi rework to make her more accessible.

Players can expect new skins to arrive in Patch 13.7, with a fan-favorite skin set returning. It's raining cats and dogs in Summoner's Rift, as four champions will get some brand-new kitty-cat and dog-themed skins.

Kled, Kindred, and, ironically, Yuumi will also be decorated in dog-themed costumes. At the same time, Nidalee will get a kitty-cat makeout. All four characters will have colorful chromas for players to truly personalize their cosmetics with for some additional flair. All four Epic-skins and their Riot Points (RP) prices are listed below.

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