ARAM Nerfs & Buffs

What Is ARAM?

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.

What Are ARAM Nerfs and Buffs?

Riot balances ARAM by modifying per-champion statistics rather than changing abilities outright. The key values are:

• Damage Dealt — A multiplier applied to all damage the champion deals. Below 100% is a nerf; above 100% is a buff. A champion at 85% damage dealt hits 15% less hard than on Summoner's Rift.
• Damage Taken — A multiplier applied to all incoming damage. Below 100% means the champion is tankier in ARAM; above 100% means they are more fragile. Ranged carries often receive increased damage taken to offset their long-range advantage in a single-lane fight.
• Healing and Shielding — Some champions have their self-healing or ally shielding increased or decreased to prevent dominant sustain strategies.
• Ability Haste, Tenacity, and Other — Certain champions receive flat stat bonuses or penalties unique to the ARAM environment.

How to Read the Data

Each champion card shows the active adjustments for the current patch. A green value indicates the champion is buffed in that category; a red value indicates a nerf. Champions with no adjustments perform identically in ARAM as they do on Summoner's Rift. You can search by champion name, filter by buff or nerf status, and sort by any stat.

ARAM: Mayhem

ARAM: Mayhem is a variant of ARAM that layers an augment system on top of the Howling Abyss experience. Players choose from randomized augments each round — global ability power, on-death explosions, movement speed modifiers, and more. The mode has its own separate set of per-champion balance adjustments.

URF (Ultra Rapid Fire)

URF is a recurring mode in which all champions have mana and energy costs reduced to zero and ability cooldowns cut by 80%. Riot applies aggressive damage and durability adjustments to prevent any single kit from dominating — those values are tracked on the URF tab of this site.

How Often Is This Updated?

League of Legends releases a new patch roughly every two weeks. ARAM balance data is updated each patch to reflect the latest official adjustments from the Riot Games patch notes.
