Basic attack

"AA" redirects here. For the item, see Archangel's Staff.

An autoattack (also called a standard, normal, basic attackand also abbreviated aa) is the default means by which a unit deals damage. Champions perform autoattacks when an enemy unit is right-clicked; autoattacks are also performed by an idle champion when an enemy unit ventures too close to it, or when the "attack move" function is used (default Shift + right-click). Champions will not automatically attack units in range if the "stop" command (default S) is used. monsters and minions perform basic attacks as their only method of dealing damage. These autoattacks are similar in nature to champion basic attacks, as they deal damage based on the unit's Attack Damage (AD) and use an attack timer which is affected by Attack Speed (AS).
Autoattacking can be disabled from in-game interface in order that a champion won't start attacking without being ordered to.

Behavior

General

Autoattacks cannot be dodged under normal circumstances. That is to say, once a basic attack has been issued from the attacker, it cannot miss the target and will follow the target despite any subsequent changes in position. Certain abilities will cause autoattacks to fail, whether by dodging, blocking, negating, missing (see:Blind) or parrying.

Champion

When using attack-move, the champion stops to attack any hostile that gets in their way en-route to a destination. If a champion has an attack target, they will continue to attack it if in range and will move closer to it when out of range, until either a new target is specified, a cancel order is issued (pressing the S key or by specifying another move order), or they lose vision of the target.

Many champions also have abilities that will affect their autoattacks in some way or form. Such abilities are treated like autoattacks and are said to apply on-hit effects.

Minions

Minions will automatically attack their closest target by default, but may change targets in a similar manner to turrets. For more information see the behavior of minions page.

Turrets

The behavior of turrets is described on the corresponding page as well as the damage of turret autoattacks. Turret autoattacks differ from regular autoattacks by increasing damage. (Every consecutive turret autoattack deals slightly more damage than the last)

Vision

Autoattacking while hiding in brush or fog of war will reveal the attacking unit, and if in brush autoattacking will reveal allies nearby while autoattacking.

Damage

Autoattacks always deal physical damage unless one of the following abilities is used, in which case the whole damage of the autoattack will be magic damage.

However, certain items, abilities or passives may cause them to deal additional magic damage on top of their base physical damage. Damage from autoattacks benefits from the attack damage stat on the attacker and are reduced by armor on the target.

When autoattacking a turret, the damage is based on the base attack damage added to either the bonus attack damage or 40% of a champion's ability power, depending on which one is higher. Even though it may use an ability power scaling on the autoattack, it still is entirely physical damage.

Attack Speed

The rate at which a champion attacks is called attack speed and is capped at 2.5; this means that a champion can attack at most, 5 times in a 2 second period.

Some abilities refresh the attack timer and allow a champion to attack again immediately if they use the ability after their autoattack.

A list of abilities that refresh the attack timer:
