Patch 25.12 has arrived, and here’s everything you need to know.
With the League of Legends Mid-Season Invitational arriving in less than a month, Riot is making some massive meta shifts, and it’s all arriving in Patch 25.12.
Starting with one of the biggest changes in this patch, Rammus mini-rework. As a champion, Rammus has been struggling quite a bit, especially against AP champions. Thus, Riot is making changes to his W – Defensive Ball Curl and giving it MR scaling so he can handle mages much easier. In addition, Riot is also making his Junlge clear more potent by adding bonus monster damage to his E – Frenzying Taunt.
In addition to the Rammus changes, Riot is adjusting Vi so that she is less dominant in Professional play. Furthermore, Riot is buffing champions like Lee Sin, Aatrox, Jax, and other champions in preparation for MSI. There are also some much-needed nerfs to champions such as Ahri, Azir, and Gwen arriving in this patch.
When Will Patch 25.12 Be Released?
League of Legends Patch 25.12 is expected to be released on June 11, 2025.
Release time and server maintenance:
- NA: 3:00 AM PT
- EUW: 5:00 UK time
- EUNE: 3:00 CET
