Intro: Patch 26.4 for League of Legends nerfs ARAM Mayhem Augments and adjusts related systems, following prior live changes and a client UI swap between ARAM modes.

Stat and utility adjustments include changes to stat anvils and their counts, higher-level movement speed and omnivamp tweaks, and reduced cooldown refunds in the Archmage Set.

Examples of nerfed Augments include limiting Poro Blaster to one pickup per team with longer stacking, reducing On Pick Up Slow for Heads Up Cupcake, and increasing Death Timer Reduction in the Deathknell Set, among other changes.

Gold and economy tweaks encompass changes to gold generation and rewards, such as replacing the 4th ARAM Mayhem mini-pass reward with Golden Reroll and adjustments to Red Envelope and Donation values.

Timing and live status notes indicate some changes shipped and live for about a week, with UI adjustments for Augment Set Panel responsiveness already implemented previously.

Augment and Set nerfs provide a comprehensive list of numerical reductions across healing, damage, speed, gold, and cooldowns, signaling a broad nerf-focused balance pass.

Overall framing emphasizes nerfs with no buffs, aiming to reduce overpowered or annoying ARAM Mayhem interactions.

Context on the rollout includes ARAM/MAYHEM client position swaps and the ARAM Mayhem mini-pass reward change, situating the patch within a broader update cycle.
