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.

Trivia

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

Therefore,

  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
