Attack damage

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

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 per unit. is the most efficient AD core item, with a gold/AD ratio of. The costs of these stats are always offset by increased final costs of their upgraded items.

Bonuses
This section lists the game elements which provide Bonus AD.

Champion abilities
Some of these abilities have multiple effects. This list only shows their bonuses to Attack Damage. For more information on each ability follow its link.

Neutral buffs

 * The buff grants up to 40 attack power and ability power (scaling with game time) for 3 minutes.
 * grants 8 / 16 / 24% (+50% with Mark of the Elder Dragon) increased attack damage if the Infernal Drake is slain.

Champion's abilities
Some of these abilities have multiple effects. This list only shows their bonuses to Attack Damage. For more information on each ability follow its link.

Note that an effect that reduces damage is not the same as decreasing a champion's attack damage.


 * reduces surrounding enemy champions' attack damage by for 4 seconds.

Alternatively killing Zeds
Two s can alternately kill each other with :

Let's say the of  1 is X and the  of  2 is Y. 1 kills first. The of the killer after n kills can be calculated as follows: of 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 of 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, of 1 after he has infinitely many kills = (X + 0.15Y)/0.9775 + 5/0.85 of 2 after he has infinitely many kills = (0.15X + Y)/0.9775 + 5/0.85
 * 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 of  1 after n kills is an, while that of  2 is bn
 * This gives the formula

Largest AD
At level 18, can reach one of the largest amounts of  possible: , Still, two champions can reach a higher AD:
 * Base AD: 
 * Runes: 
 * 9 (+9 AD)

 * 3 (+3 AD)
 * Masteries:, 
 * 5 points in (+4% AS)
 * 5 points in (+10 AD)
 * 1 point in fully stacked (+64 AD)
 * Items:, , 
 * Two of any 75- items: 2(+75 AD)
 * A combination of three items of any of the following: 3(+70 AD, +20% critical chance)
 * fully stacked (+53 AD, +73% AS)
 * Buffs: , ', '
 * with the maximum amount of ability power (+ AD)

 * At level 18, base attack damage ranges from 63 to 146.
 * The ability with the largest AD ratio is, with a possible maximum AD ratio of.
 * To achieve that must be rank 3 and  needs a full runepage of critical strike damage runes, 100% critical strike chance and at least 1.
