LoL Patch 14.12: Champion Mastery Changes, Mythic Shop Updates, and New ARAM Cup

12. June 2024 by Valentin Pasetti

The latest update, Patch 14.12, for League of Legends brings a host of exciting changes and improvements. This patch addresses the recently introduced Champion Mastery system, offers significant modifications for ARAM players, and refreshes the Mythic Shop. 

Champion Mastery Updates

Since the release of version 14.10, the updated Champion Mastery system has been a topic of discussion. While certain aspects, such as the removal of the mastery cap and the ability to unlock champion titles, have been positively received, other elements have not fared as well.

In response to player feedback, Riot Games is making adjustments. The first major change is the reduction in requirements for the additional mastery objective, now needing just three S-grade games instead of seven. Expect more changes in the future, and players are encouraged to check the developer update for more information.

Bug Fixes and Functionality Changes

Finally, the patch includes several bug fixes and functionality changes. A notable change is the modification of how successful ability casts are displayed. Previously, the critical hit symbol was used, causing confusion as it did not represent an actual critical hit. Moving forward, a different icon will be used to indicate these situations.

These updates in Patch 14.12 aim to enhance balance and clarity in the game, providing a more satisfying experience for League of Legends players.
