Attack damage

Attack damage (AD) is a value affecting the damage a unit or champion is able to deal by increasing the damage dealt by basic attacks and abilities. While every basic attack deals damage equivalent to the champions attack damage (before applying damage modifiers), abilities scale with a percentage of the champions attack damage that can range between 0% and.

Attack damage consists of two parts: Base AD and Bonus AD. This differentiation is important as abilities are scaling with either bonus AD or total AD, while certain item effects are scaling with only the base AD.
 * Base AD is the portion of attack damage originating from the champion itself, consisting of a constant base value that is individual for every champion and a component granting AD on leveling up.
 * Bonus AD is the portion of attack damage originating from runes, masteries, abilities, aura effects and, most importantly, items.
 * The sum of both Base AD and Bonus AD is called Total AD.

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

Attack Damage has a theoretical gold value of per unit. This means that is the most efficient AD core item, with a gold/AD ratio of 32.5. The costs of these stats are always offset by increased final costs of their upgraded items.
