Attack Damage (AD) is the amount of damage dealt by a basic attacks excluding the applicable damage modifiers.

Attack damage is the sum of two components: Base AD and Bonus AD.

  • Base AD is the portion of attack damage which originates from the champion itself. It is the sum of a constant base value that is individual for every champion plus a growth component which increases as the champion levels up.
  • Bonus AD is the portion of attack damage which originates from runes, abilities, auras and, most importantly, items.

The damage dealt by some abilities is proportional to either bonus AD or total AD. That proportionality ranges between 0 and 12. The effect of some items is proportional to base AD.

This statistic stacks additively. Percentile attack damage bonuses are applied after adding up the AD granted from all additive sources.

The theoretical gold value of Attack Damage is Gold 35 per unit. B. F. Sword item B. F. Sword is the most efficient AD core item, with a gold/AD ratio of Gold 32.5. The costs of these stats are always offset by increased final costs of their upgraded items.

Alternatively killing Zeds

Last updated: March 10, 2017 – V7.5

Two ZedSquare Zeds can alternately kill each other with Death Mark Death Mark:

Let's say the AD of ZedSquare Zed 1 is X and the AD of ZedSquare Zed 2 is Y. ZedSquare Zed 1 kills first. The AD of the killer after n kills can be calculated as follows:

  • Define two sequences A= {an} and B= {bn}, where n = 0, 1, 2...
  • a0 = X, b0 = Y
  • For n ≥ 1, an = X + 5 + 0.15bn-1, bn = Y + 5 + 0.15an
  • The AD of ZedSquare Zed 1 after n kills is an, while that of ZedSquare Zed 2 is bn
  • This gives the formula
  AD of ZedSquare Zed 1 after his nth kill
  = X(1 - 0.152n)/0.9775 + 0.15Y(1 - 0.152n)/0.9775 + 5(1 - 0.152n-1)/0.85
AD of ZedSquare Zed 2 after his nth kill = 0.15X(1 - 0.152n)/0.9775 + Y(1 - 0.152n+2)/0.9775 + 5(1 - 0.152n)/0.85


  AD of ZedSquare Zed 1 after he has infinitely many kills = (X + 0.15Y)/0.9775 + 5/0.85
  AD of ZedSquare Zed 2 after he has infinitely many kills = (0.15X + Y)/0.9775 + 5/0.85

Largest AD

Last updated: November 10th, 2017 – V7.22

Without using Gathering Storm rune Gathering Storm which potentially allows for infinite amounts of attack damage, the largest amount of attack damage is reached with a level 18 JhinSquare Jhin at 2645.7698493 AD. Still, HecarimSquare Hecarim can potentially reach a higher AD with 8419.232831 movement speed or higher.


  • At level 18, base attack damage ranges from 71 (Miss FortuneSquare Miss Fortune) to 153 (IllaoiSquare Illaoi).
  • The ability with the second largest AD ratio is Miss FortuneSquare Miss Fortune's Bullet Time Bullet Time, with a possible maximum AD ratio of 1560% AD.
  • The ability with the largest AD ratio is KalistaSquare Kalista's Rend Rend, with a possible maximum AD ratio of (7650% AD)
    • To achieve that Rend Rend must be rank 5 and KalistaSquare Kalista needs to stack 254 spears on a target before using Rend Rend.
