Ability effects

On-hit effects are effects that trigger on a champion's autoattacks.

Applying On-Hit Effects
On-hit effects will trigger on a champion's autoattacks and abilities that state in their description that they do so.

An autoattack or ability that applies on-hit effects can apply any number of these effects at once. On-hit builds (aka attack speed builds) consisting of items such as  or . Which are popular some on champions with their own on-hit effects as the attack speed allows for the most efficient use of the on-hit damage.

In some instances, critical strike and life steal are disabled for the triggering attack. Unless that is the case, the attack that triggers the on-hit effect can still critically strike and apply life steal. In most cases, critically striking will not affect the damage of the ability.

The apparent definitions for whether an on-hit effect applies on-ability effects or not are as follows:
 * An on-hit damage modifer (i.e. all your autoattacks deal bonus damage), on-hit damage-over-time or on-hit splash damage (i.e. cleaves/damages nearby enemies) does not apply on-ability effects.
 * An effect that consumes a mark or applies area of effect damage will apply on-ability effects. There are some exceptions.

Abilities which apply on-hit effects
Some abilities can also apply on-hit effects. These abilities are classified as autoattacks, and will apply on-hit effects instead of on-ability effects. To emphasize: these abilities do not apply spell vamp, or.

Note that critical strike is not considered an on-hit effect and will not apply unless otherwise stated. Also, unless otherwise stated, life steal will only apply to physical damage.

Unless life steal is explicitly disabled by the effect, any physical damage dealt by the ability will apply life steal. This is in addition to the life steal applied to the triggering attack (again, unless disabled). Any non-physical damage does not incur any healing.
