Balance changes for every League of Legends champion across ARAM, ARAM: Mayhem and URF — damage dealt, damage taken, healing, shielding, and more. Updated every patch.
ARAM — All Random All Mid — is a League of Legends game mode played on the single-lane Howling Abyss map. Players are assigned a random champion from a shared pool and fight in a continuous team battle until one team destroys the enemy Nexus. Because the map offers no way to return to base and no side lanes to rotate through, champion kits that excel in a normal 5v5 match can become wildly overpowered or nearly useless in the compressed environment of the Abyss.
To keep the mode fun and competitive, Riot Games applies a dedicated set of ARAM balance adjustments — separate from the standard Summoner's Rift patch — that tune each champion's performance specifically for the Howling Abyss.
Riot balances ARAM by modifying a handful of per-champion statistics rather than changing champion abilities outright. The key values tracked on this site are:
Each champion card shows the active adjustments for the current patch. A green value indicates the champion is buffed in that category relative to baseline; a red value indicates a nerf. Champions with no adjustments listed perform identically in ARAM as they do on Summoner's Rift.
You can search by champion name, filter by class or role, and sort by any stat to quickly identify which champions are strongest or weakest in the current ARAM meta.
ARAM: Mayhem is a limited-time variant of ARAM that layers an augment system on top of the standard Howling Abyss experience. Players choose from randomized augments each round that drastically alter gameplay — global ability power, on-death explosions, movement speed modifiers, and much more. The mode has its own separate set of per-champion balance adjustments that differ from standard ARAM.
URF is a recurring limited-time mode in which all champions have their mana and energy costs reduced to zero and ability cooldowns cut by 80%. The result is a chaotic, ability-spamming experience. Riot applies aggressive damage and durability adjustments to champions in URF to prevent any single kit from dominating — those values are tracked separately on the URF tab of this site.
League of Legends releases a new patch roughly every two weeks. ARAM balance data on this site is updated each patch to reflect the latest official adjustments published in the Riot Games patch notes. The current patch is displayed at the top of each page.
