Basic attack

A basic attack (also called a standard, normal, or auto attack) is the default means by which a unit deals damage. Champions perform basic attacks when an enemy unit is right-clicked; basic attacks 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 ). Monsters and minions perform basic attacks as their only method of dealing damage. These basic attacks 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).

Certain abilities can 'reset' the basic attack timer, causing the basic attack to queue in prematurely before the second basic attack initiates the queue, resulting in a faster second attack rather than basic attacking twice normally. Examples of this are, , and.

Auto attacking
By default, a champion will automatically attack nearby enemy units. This feature can be turned off in the options menu.

Auto attacking can be momentarily disabled by using the "stop" command (default S ).

General
Basic attacks 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 basic attacks 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 basic attacks in some way or form. Such abilities are treated like basic attacks 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 basic attacks. Turret basic attacks differ from regular basic attacks by increasing damage. (Every consecutive turret basic attack deals slightly more damage than the last)

Vision
Basic attacking while hiding in brush or fog of war will reveal the attacking unit, and if in brush basic attacking will reveal allies nearby while basic attacking.

Damage
Basic attacks always deal physical damage unless one of the following abilities is used, in which case the whole damage of the basic attack 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 basic attacks benefits from the attack damage stat on the attacker and are reduced by armor on the target.

When basic attacking 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 basic attack, it still is entirely physical damage.

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

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