Patch 25.15 for League of Legends focuses on nerfing champions empowered by recent item updates, following the conclusion of MSI 2025 and Esports World Cup 2025. Riot targets power spikes from Kraken Slayer and Blade of the Ruined King while also reducing the impact of top-performing supports and solo laners.

The new patch arrives as a balance reset after a string of updates that favored champion scaling. Developers are shifting attention toward trimming overperforming picks, especially those benefiting from recent item changes. Riot also addresses tank supports and solo queue outliers, aiming to stabilize the meta ahead of the next ranked phase.
