Attack damage

Damage (or Attack Damage, AD) directly increases the Physical Damage of a Champion. Bonus damage is calculated before damage reduction from armor. This statistic scales additively; meaning that each bonus point acquired directly affects the statistic. The total amount of physical damage is calculated by basic damage + bonus damage.

At level 18, base damage ranges from 93 to  130.
