Patch 25.21 is officially live in League of Legends, coming with a slew of buffs, nerfs, and more! We’re starting to enter the slow period of updates, where Riot Games stops adding so many things to make a fair Worlds experience for the year.

Diana Jungle (Iron to Diamond 2)
Kog’maw Bot (Iron to Diamond 2)
Morgana Mid (Iron to Challenger)

Adjustments are changes to systems that don’t necessarily count as nerfs or buffs, but rather, they give the champion a different identity. For more information about the size of the changes, don’t forget to check out the specific patch notes to learn more about them.

Other Changes (Items and Runes):

As an Act-starting patch, there are a few additions that have been made to the patch. There is a new game mode, the extension of an old one, and a new Battle Pass! Here’s what you need to know:

Season 3 Act 2 Battle Pass is live. A portion of the proceeds will be shared with the LoL Esports teams.
ARAM Mayhem is officially out, and it will continue through patch 25.24, giving you until the 3rd of December to try it out.
The Practice Tool has been updated, adding all champions in solo mode (bots and spectators are allowed), the opportunity to spawn/respawn neutral monster camps (jungle and scuttle crab), and a bug fix where scuttle crab wouldn’t respawn.
Brawl Game Mode has been extended through Patch 25.22, meaning that it’ll go away when Patch 25.23 goes live (on the 19th of November 2025)

Patch 25.22 will be live on the 5th of November 2025.
