League of Legends Patch 26.4 introduces significant updates, including champion rebalancing, new skins, and system adjustments. The patch celebrates the Lunar Revel event with Petals of Spring skins for champions like Camille, Jayce, Katarina, Lillia, Yasuo, and a special Aurelion Sol skin, which will be limited-time and vaulted in Patch 26.6. Winter skins also return for a limited period. Major champion nerfs include Ambessa, Aphelios, Braum, Gwen, Jinx, Kassadin, Kayle, Kennen, Naafiri, Qiyana, Rengar, Rumble, Twitch, and Zac, targeting their roles across various ranks from Emerald to Challenger. Conversely, buffs are applied to champions such as Annie, Brand, Camille, Darius, Fizz, Graves, Hwei, Illaoi, Lux, Maokai, Samira, Teemo, Udyr, and Xayah to improve their viability. System changes include the removal of Omnivamp from Smite and Ignite to maintain consistency, as Omnivamp now applies only to damage dealt by items or runes, not summoner spells. The Hexoptics C44 item is buffed to reduce its maximum bonus damage range, and its bonus duration from takedowns is increased from six to eight seconds, making it more attractive in late-game scenarios. New events such as the ARAM Mayhem and Ionia Cup Clash are introduced, with ARAM adjustments and bug fixes enhancing gameplay. The patch also addresses numerous bug fixes across champions and systems, improving stability and gameplay clarity. Additionally, the patch features several new skins and chromas, celebrating the season's themes. Overall, Patch 26.4 balances champion power levels, updates item and spell effects, and introduces engaging new content, ensuring a dynamic and fair gameplay experience for all players.
