Update 25.17 has brought a multitude of changes: the return of the standard Summoner's Rift map, the return of the "Nightmare Bots" mode, a rework of Xin Zhao, a new battle pass, improvements to game information tracking mechanics, and numerous bug fixes.

New Battle Pass and Rewards
With the start of the third season in League of Legends, a new battle pass has arrived! Among its rewards are Arcana Lulu skins, Arcana Jhin, Prestige Jarvan IV Vision of the Fallen, emotes, icons, and much more. For the first time, the battle pass reflects a change from 50 to 48 levels, while the experience per level remains the same, making it slightly quicker to complete.

Start of the Third Ranked Season
The third ranked season kicks off on August 27 at 12:00 local time. LP and progress towards the next rank will not be reset, only the quest for obtaining the victorious skin (15 wins in ranked matches) will be updated. Ranked games will be unavailable for approximately 12 hours, and rewards for the end of the second season will appear a few days after the start of the third.

Atahan's Change
Atahan now has a weapon, affecting only the visual aspect, with no mechanical changes.

Xin Zhao Visual Update
The "Commando Xin Zhao" and "Imperial Xin Zhao" skins have increased in price from 520 RP to 750 RP. A new music theme will be released on August 29, and champion pages in the Universe have been updated to reflect the events of 2025 and previous seasons.
