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.

Champion Buffs
Kled – Slightly buffed after losing 0.8% win rate last patch; remount reliability improved for teamfights.
Riven – Partial revert of previous nerfs due to overcorrection.

Champion Nerfs
Alistar – Statistically dominant and the top pro support; receiving direct nerfs.
Bel’Veth – Loses early-game strength and some scaling after synergy with Kraken Slayer and BotRK.
Braum – Further nerfed following ineffective adjustments in the last patch.
Irelia – Targeted nerfs following strong item-based performance, especially in solo queue.
Master Yi – Crit builds elevated his performance; nerfed with some compensation.
Nilah – Highest bot lane win rate; scaling reduced, slight early buff added.
Pantheon – Delayed nerf from previous patch, focused on jungle performance.
Quinn – Nerfed for early-mid wave clear power while maintaining attack damage.
Rell – Brought down from overperforming levels, especially in support role.

Champion Adjustments
Corki – Laning slightly softened to reduce sharp power spikes while maintaining late-game curve.
Illaoi – Vessel debuff duration reduced to ease frustration without overbuffing.
Rek’Sai – True damage returns to E; R reworked into a more flexible assassination tool.

Patch 25.15 lands after MSI 2025 and the Esports World Cup 2025, where item-driven champions and tank supports shaped the meta. Riot’s update aims to reset power balance and limit snowball potential from outlier builds as competitive and solo play transitions into the second half of the season.
