League of Legends’ Mid-Season Invitational is just around the corner, and the developer is ready to start making small changes across the board, which bring champions up to current standards and prepare them for the international tournament.
This League patch changes are hitting a large number of champions, who have been part of the meta and outside it as well. As stated by the developer in the last patch, the meta is looking stable, so don’t expect your favorite champion to get some love or go under the nerf hammer.
When does LoL Patch 25.12 release?
League updates are usually released on Wednesdays, and this remains consistent for every upcoming patch. They usually land on the PBE servers first and gradually make their way to the live servers. The patch 25.12 update is scheduled for June 11, 2025. While the official release times across all regions have yet to be confirmed, the expected release windows for each region are as follows:
- 3pm CT (NA)
- 5am GMT (EU West)
- 3am CET (EU North East)

What’s in Patch 25.12?
Several League champions are getting minor changes to make them ready for the upcoming MSI 2025, which will feature Fearless Drafts just like the rest of the year’s tournaments. Since the format introduces a large number of champions into the mix, the developer is ensuring they’re well-balanced to take center stage. We’ll also have the Inkshadow skins along with the Uzi Hall of Legends skins coming in the patch.
