On-Action Effects

On-action effects is a catch-all term for additional effects of a champion's actions as caused by an item, ability, or passive of a champion. Actions in this case include Standard Champion Auto-Attacks; Improved Auto-Attacks which will still occur even if the attack is dodged or blocked, or the attacker is blinded; non-basic attack damage from pets; basic attacks from pets; taking damage from a player, minion, monster, or pet; and champion abilities. Actions will always trigger as many on-action effects as are applicable and from this fact a split into four rough categories, each with a principle example, can be made with On-strike effects including on-hit effects, on-spell effects including spell effects, ability modifiers including critical strikes, and triggers including on-damage-taken effects (defensive triggers).

On-Hit Effects
On-hit effects are effects that trigger on a champion's autoattacks and a select few abilities. An autoattack or ability that applies on-hit effects can apply any number of these effects at once.

Abilities that apply on-hit effects
The following abilities will apply on-hit effects instead of spell effects. Any ability not listed here will apply spell effects, regardless of how similar it may be to the abilities on this list or how similar to effect resembles a basic attack.
 * (physical component)
 * Urchin Strike has two damaging components: one physical that applies on-hit effects and one magical that applies spell effects.
 * (classified as a melee attack)
 * (counts as attacking twice; applies on-hit and on-attack effects twice)
 * (counts as attacking twice; applies on-hit and on-attack effects twice)

 * (on every target hit)
 * (up to 5 times)
 * Applies life steal despite dealing magic damage.

Pets that apply on-hit effects

 * Deals 75% of Shaco's attack damage, and any cloned on-hit effects at full damage. The clones attacks can critically strike and any life steal will heal itself.
 * Deals 45 / 60 / 75 % of Yorick's attack damage, and any copied on-hit effects at full damage but the clone's attacks can critically strike but it won't trigger life steal.
 * Deals magic damage equal to the target's base AD at level 1 + 100% of the target's bonus AD + 75% of Mordekaiser's AD (not including the 20% increase from Children of the Grave). It will apply any cloned on-hit effects sourced from items but not those sourced from champion abilities. Despite not applying spell effects, it will generate shield through. The clone's attacks can critically strike but it won't trigger life steal.
 * Deals 0% of LeBlanc's attack damage but will apply any cloned on-hit effects at full damage. Whether or not the mirror image can critically strike or trigger life steal is irrelevant as it has no basic attack damage unless you equip.

Physical Damage
The damage dealt by these effects will apply life steal unless otherwise stated.



Non-Physical Damage
These abilities will not incur any healing. In all cases, the triggering attack will still apply life steal.



Damage Over Time
These abilities will not incur any healing. In all cases, the triggering attack will apply life steal.



Splash Damage

 * For the full article, see area of effect.

The damage dealt to enemies other than the original target will not trigger on-hit effects or spell-effects. If the attack misses or is blocked, the effect will not trigger.



Non-Damaging
The following abilities have a non-damaging on-hit effect component:



Exceptions
The following "on-hit effects" are classified as abilities and will trigger spell effects, rather than on-hit effects. It is unknown of this behaviour is an oversight or intentional as they are visually identical to the on-hit effects of other champions. The triggering attack will still trigger on-hit effects.



Pets

On-Attack Effects/Auto-attack Modifiers
The following effects occur when your champion attacks or modifies your champion's basic attacks to behave differently. These effects are not triggered "on-hit", and will still occur even if the attack is dodged or blocked, or the attacker is blinded. On-attack effects consistently apply spell effects unless stated otherwise, with one exception.

 * Note that the triggering attack still applies on-hit effects as normal, except where stated.

 * (the activation of Entropy counts as casting an ability, and so will trigger effects like )

On-Attack Effects
The following effects occur when your champion attacks, rather than when the attack hits. They will trigger even if the attack is blocked or dodged, or if the attacker is blinded.

Lifesteal

 * Life steal is an offensive stat that converts a percentage of the physical damage dealt by a champion's basic attack or ability that applies on-hit effects to health regained. For the main article, see life steal.

Life steal applies to all physical damage dealt on-hit, including any sourced from on-hit effects (with a few exceptions). and is a renowned example of powerful sustain as life steal not only applies to the basic damage on the attack, but the bonus damage on Sheen and the stacked damage on Siphoning Strike.

Life steal is calculated from the actual damage done to an enemy after armor and all other forms of damage reduction. Almost all champions have 0% base life steal. It can be increased with items, runes, masteries, and some champion abilities.

Damage dealt to enemies beyond your target through splash damage will not apply life steal. That is unless the damaging effect specifically states that on-hit effects will apply to all enemies damaged (such as and ).

Spell Effects
Spell effects are effects that trigger on a champion's damaging abilities. They apply to all damaging abilities, with the exception of on-hit effects or abilities that specify that they apply on-hit effects. Abilities can apply any number of spell effects at once.

Additionally, spell effects will apply other spell effects - creating synergy between effects such as and. In the case of spell effects such as : a spell effect will not trigger itself.

Critical Strikes
Critical strike is not considered an on-hit effect. A few select abilities can critically strike (,, and ), but this should not be mistaken for standard functionality.

In almost all cases, the attack that triggers an on-hit effects may still critically strike and apply life steal. Also in most cases, critically striking will not affect the damage of the on-hit effect, unless explicitly said otherwise, such as. A critical strikeEfekty przy trafieniu is a modifier that causes an auto-attack or ability to deal a flat multiple of its normal damage. This could represent an attack that hits harder, a lucky strike or damaging a weak area on an opponent.

Players can increase the chance and the damage of critical strikes with items, abilities, and runes.

It only applies to basic attacks or certain abilities like and  that act like a basic attack or  and ,which are specially stated.

It's important to note that you cannot score a critical strike against a building such as a turret or inhibitor.

Chance
Critical strike chance is the chance of a champion's physical attacks dealing a critical strike. Critical strike chance stacks additively. Runes, items and all abilities can increase critical strike chance.

When averaged over a large number of autoattacks and at base critical damage, critical strike chance is essentially a damage multiplier where each % of crit chance adds 1% damage. Thus at 50% critical strike chance a champion will be doing (on average) 150% damage with autoattacks, not counting critical strike damage. Because of this, critical strike chance scales well with both attack damage and attack speed. The formula for this damage multiplier is given by:

% Damage multiplier = %Crit chance x (%Crit Damage - 100%) + 100%

The maximum critical strike chance you can reach at level 1 through masteries is, excluding abilities and items.

Critical strike chance has a hard cap at 100%.

Critical strike chance has a theoretical gold value of 50 gold per 1% critical strike chance. This makes Cloak of Agility the most efficient core item for critical strike chance, as it grants 15% critical chance for the cost of 730 gold with a gold per % crit chance efficiency.

Damage
Critical strike damage refers to the amount of damage that a champion's critical strike will deal. All champions have 200% critical strike damage by default.
