ARAM Mayhem is a rotating variant of ARAM that keeps the all-random, blind, no-bans champion select on the ARAM maps but layers on Arena-style augments, mode-exclusive items and summoner spells, and a 32-level Mayhem Progression Track. It launched on October 22, 2025 alongside Trials of Twilight: Act II and was extended past its original limited-time window after positive feedback. So yes, it is a genuine ARAM variant (your champion is still randomized), and the augment system is the headline difference. The rest of this guide covers the augments, the exclusive content, how it differs from standard ARAM, and whether it is permanent.
What Is ARAM Mayhem?
ARAM Mayhem is a Featured Game Mode and an altered version of regular ARAM. It is one of many League of Legends game modes, and it uses the same draft type as ARAM, all random, blind, and no bans, and it is played on three maps: Howling Abyss, Butcher's Bridge, and Koeshin's Crossing. Its most prominent feature is the addition of augments, power-ups that enhance your champion mid-game.
The mode was released alongside Trials of Twilight: Act II on October 22, 2025. It was originally scheduled to remain available only until the end of the 2025 Annual Cycle, but positive feedback led Riot to extend its run beyond that limited-time window. The wiki classifies it as a rotating Featured Game Mode, and it was live as of patch V26.11. For the base ARAM ruleset that Mayhem builds on, see our What Is ARAM guide.
ARAM Mayhem vs Standard ARAM
The headline differences are the augment system, mode-exclusive items and summoner spells, the 32-level progression track, and a Combo Breaker anti-crowd-control mechanic. Mayhem also disables runes entirely, with some Keystones available only through augments, and it changes a few summoner spells: Exhaust is disabled and Ignite counts as a Burn source. Champion select itself is unchanged from ARAM.
| ARAM Mayhem | Standard ARAM | Normal SR | |
|---|---|---|---|
| Map | Howling Abyss, Butcher's Bridge, or Koeshin's Crossing | Howling Abyss / Butcher's Bridge / Koeshin's Crossing (rotating) | Summoner's Rift |
| Team size | 5v5 | 5v5 | 5v5 |
| Champion select | All random, blind, no bans (same as ARAM) | All random, blind, no bans, with rerolls | Full draft with bans |
| Augments | Yes (Silver, Gold, and Prismatic tiers, with set bonuses) | No | No |
| Tempo modifiers | Exclusive items and summoner spells, global stat buffs, Combo Breaker, 32-level progression track | Global stat buffs (ARAM balance changes) | None |
| Runes | Disabled (Keystones via augments only) | Enabled | Enabled |
| Availability | Rotating (Featured Game Mode) | Permanent | Permanent |
Note that base ARAM also rotates onto Butcher's Bridge, so the map list is not the real distinction. What sets Mayhem apart is the augment layer and the exclusive items and spells stacked on top of the standard all-random format. For how the base mode plays, including reroll mechanics and the Howling Abyss map, see What Is ARAM.
How Augments Work in ARAM Mayhem
Augments come in three rarity tiers: Silver (least potent), Gold (moderately powerful), and Prismatic (the rarest, with extraordinary effects). When you hold two or more augments from the same themed set, a set bonus activates, which rewards building around a theme rather than picking each augment in isolation.
You fill four augment slots over the course of a game, drawn from the initial selection and from level breakpoints. A fifth slot can be filled by select special augments. The augment selection screens unlock at the start of the game (level 3) and again at levels 7, 11, and 15.
Each selection screen offers three augments. You pick one, and you can reroll one offering once at the same tier, giving you up to six total choices per screen. Every player is offered the same tier on a given screen, and that tier is random each time, with one rule: the first and second screens cannot both offer Silver-tier augments. Selection screens only appear while the shop is enabled, which means while you are dead or standing in shopping range at the spawn platform.
Golden Rerolls add a third option. They unlock through the level-4 reward on the progression track, and they bump an offered Silver or Gold augment up one tier. The chance of getting a Golden Reroll increases at progression levels 13 and 31.
The Mayhem Progression Track and Exclusive Content
Playing ARAM Mayhem earns Mayhem XP (MXP), which progresses you through a 32-level Mayhem Progression Track. Each level grants an exclusive reward, including special augments, emotes, profile icons, and a banner. The Golden Reroll chance from the augment system is tied to this track: it first unlocks at track level 4 and increases at levels 13 and 31.
Mayhem also brings content you will not find in standard ARAM. The mode-exclusive legendary items are Atma's Reckoning, Rite of Ruin, and Sword of Blossoming Dawn, and they are only available in ARAM when you are playing ARAM Mayhem. The mode-exclusive summoner spells are Bounce of the Poro King, Droppybara, Growth Spurt, Poltergeist, and Laser Heal.
On top of the items and spells, Mayhem applies global stat changes to every champion and adds a Combo Breaker mechanic that fights back against crowd control. Being hit by immobilizing crowd control grants tenacity for each disable applied outside concurrent immobilizations, lasting 3.25 seconds and refreshing on later triggers. If you are immobilized for 5 of the last 7 seconds, you are cleansed of all crowd control and become immune to it for 3 seconds.
Is ARAM Mayhem Permanent? (And Does It Count as ARAM?)
ARAM Mayhem is not a permanent mode the way the standard ARAM queue is. It is a rotating Featured Game Mode. It launched on October 22, 2025, was originally limited to the end of the 2025 Annual Cycle, and then had its run extended after positive feedback. It was live as of patch V26.11. Because it is a rotating mode, it can leave the queue between rotations, so check the in-client mode picker or the latest patch notes for current availability rather than assuming it is always there.
As for whether Mayhem games count as ARAM for progression, the wiki does not document whether they feed ARAM missions, ARAM key fragments, or ARAM MMR. What is confirmed is that Mayhem is an ARAM variant with the same all-random champion select. For how those standard ARAM systems work, see our guides on ARAM missions, ARAM key fragments, and ARAM MMR. If you are deciding whether to grind the Mayhem track or the regular ARAM reward loop, treat the Mayhem-specific interaction as unconfirmed until Riot states it directly.
