The last League of Legends patch 13.14 brought some of the biggest changes of the year to the game, including new champion Naafiri, the Soul Fighter Summer event, and the new 2v2v2 Arena game mode.

The LoL patch notes for 13.15 seem tame in comparison, only bringing some slight balance changes and other key adjustments to Riot Games' popular MOBA.

The Tournament of Souls continues with five new Soul Fighter skins to add to the set and other champion adjustments across the board. Here are all the changes coming in the upcoming LoL patch 13.15.


According to Riot Games' official patch schedule, the League of Legends patch 13.15 is set to go live on August 2, 2023

The patch will be rolled out across the day according to all major league servers' time zones - here are all the critical patch rollout times for all major LoL servers worldwide.

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

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


Plenty of changes will be sweeping over Summoner's Rift with the League of Legends patch 13.15. These changes include several champion buffs, nerfs, and system changes as Riot Games begin preparing for the LoL Worlds meta.

Since Naafiri's launch in patch 13.14, she has emerged as a strong contender in the meta, despite her low win rate of below 50%. As such, Riot will be tweaking her damage capabilities and bringing her back in line with other mid-lane champions. Kai'Sa also currently dominates the battlefield with her AP build in professional play, so Riot is attempting to rein that in.

The two brothers, Yone and Yasuo, are currently lacklustre picks in the meta, following the ADC mythic item rework. The balance team plans to give them some love in LoL patch 13.15.

Open up your wallets to buy some RP as the Soul Fight skin set is expanding with five new debutants. These skins resemble the ones in the Tournament of Souls mini-game mode and look well worth the money!

  •  Soul Fighter Evelynn - 1,350 RP
  • Soul Fighter Gwen - 1,350 RP
  • Soul Fighter Jhin - 1,350 RP
  • Soul Fighter Shaco - 1,350 RP
  • Prestige Soul Fighter Shaco - 2,000 Soul Fighter Event Tokens
  • Soul Fighter Viego - 1,820 RP
