Attack damage (AD) is the stat that determines the amount of physical damage dealt by basic attacks. AD also determines the damage of various champion abilities, items and runes.
Total attack damage is comprised of base attack damage and bonus attack damage.
The base attack damage is innate to the champion. It does not depend on items or runes and increases with each champion level (see List of champions' attack damage).
Bonus attack damage can be gained from items, abilities and runes. Increasing the bonus AD is the typical way to scale up the damage output of an AD-based champion. Attack damage 
stacks additively.
Effects that benefit from attack damage receive a bonus based on a certain percentage of either base attack damage (base AD), bonus attack damage (bonus AD) or total attack damage (AD).
Gold Value
- Attack damage has a theoretical gold value of
35 per point.
Attack damage as a scaling stat
Many abilities, items, and runes benefit from attack damage through their AD ratios. They can count base AD, bonus AD, and/or total AD. Note that attack damage does not always apply to physical damage; ratios can be assigned to any damage type.
The following champions do not have an AD ratio on any of their abilities:

Trivia
Largest AD
Last updated: July 22, 2020 – V10.17
Without using Senna's 
Absolution, 
Gathering Storm, 
Prototype: Omnistone or 
Pyke with 
Grasp of the Undying or 
Overgrowth which potentially allows for infinite amounts of attack damage, the largest amount of attack damage is reached with a level 18 
Jhin at 3408.294591 AD. Still, 
Hecarim can potentially reach a higher AD with 10959.6486 movement speed or higher.
- Base AD: +138.9 AD
- Runes:
- Items:
- Sanguine Blade (With Blood Pursuit active)
- Guinsoo's Rageblade (fully stacked)
- Molten Edge
- 3x Infinity Edge
- Buffs:
- Hand of Baron
- Elixir of Wrath
- Ardent Censer
- Janna's Eye of the Storm (with the maximum amount of ability power)
- Nidalee's Primal Surge
- Yuumi's Zoomies
- Yuumi's You and Me!
- AD Multiplier:
- Janna's AP:
- Items = 175 + 120 × 2 + 200 + 145 + 148.64 = 908.64 AP
- Seraph's Embrace's AP = 50 + ( 1438 + 200 + 250 + 1400) × 0.03 = 148.64 AP
- Runes = 30 + 30 + 30 + 9 × 2 = 108 AP
- Buffs = 80 + 50 + 20 = 150 AP
- AP Multiplier = (1 + 0.4 + 0.16 + 0.2) = 1.76
- Janna's AP = (908.64 + 108 + 150) × 1.76 = 2053.2864 AP
- Eye of the Storm's bonus AD = 40 + 0.1 × 2053.2864 = 245.3286 AD
- Items =
- Jhin's attack speed:
- Jhin's critical strike:
- Jhin's Bonus AD:
- AD Multiplier:
- Jhin's Total AD = (138.9 + 824.7286 × 1.2) × 3.02 = 3408.294591 AD
- Hecarim Bonus AD needed = 3408.294591 − 120.4 = 3287.894591
- Hecarim MS needed = 3287.894591 / 0.3 = 10959.6486
Other
- At level 18, base attack damage ranges from 50 ( Senna) to 153 ( Illaoi).
- The ability with the second largest AD ratio is Miss Fortune's Bullet Time, with a possible maximum AD ratio of 1440% AD.
- To achieve that Bullet Time must be rank 3 and Miss Fortune needs 100% critical strike chance.
- To achieve that
- The ability with the largest AD ratio is Kalista's Rend, with a possible maximum AD ratio of (8915% AD)
