For the summoner experience, see experience (summoner).
Champion experience (XP) is a game mechanic that allows champions to level up after reaching certain amounts of experience. Leveling up allows them access to new abilities or higher ranks of existing abilities. Many base stats and some items and runes scale with champion's level.

Experience isn't gained over time, it has to be earn through different ways.

Gaining experience

There are five ways to gain experience.

  • Killing a champion: Gives 50% of the experience difference between the slain champion's current and next level.
    • Kill Experience = ((slain's champion current level experience) - (slain champion's next level experience)) × 0.5
    • This is increased or decreased by 7% per level difference higher or lower the slain champion is, but cannot be lower than 20%.
  • Assisting a kill: Gives the same experience as a champion kill but the experience is shared equally through all assisting allies.
  • Proximity to a minion death: Being within 1600 units of a minion's death grants experience, regardless of whether it was last hit or killed by another source.
  • Jungle monsters: Killing a monster grant experience. All experience goes to the killer, even if there is allies nearby.
  • Structures death: The inhibitor and inhibitor's turrets grant experience globally on death. All other structures don't grant experience on death.

Increasing experience gain

Note that experience gain modifiers stack additively.

Champion abilities

Neutral buffs

  • Howling Abyss aura Howling Abyss Aura passively grants experience.
  • Crystal Scar's Aura passively grants 7.2 experience per second, while playing on the Dominion game mode.

Sharing experience

In addition, when more than 1 champion is sharing experience, 30.4% extra experience is split among all champions.[1]

  • Two champions each gain 65.2%.
  • Three champions each gain 43.46%.
  • Four champions each gain 32.6%.
  • Five champions each gain 26.08%.

Level cap

By default, and in most gamemodes, the level cap is set to level 18.

When reaching the maximum level, the in-game tooltip for experience will show 0/0 Experience. Champions will still be able to experience, but it has no effect whatsoever.
