Damage Annie

Damage is displayed as a red section on a champion's health bar.

Note: Not to be confused with attack damage, a champion statistic, nor health costs.

Damage is the deduction of a unit's current health as a result of an offensive interaction.


Damage types

There are three types of damage in League of Legends.

Critical damage

Critical damage is an additional tag applied to critical strikes and some abilities. Critical damage will be reduced by Randuin's Omen item Randuin's Omen, triggers Critical strike icon impact text, as well as the highest instance of critical damage being tracked in the post-game stats.

Pet damage

Pet damage is an additional tag applied to the damage inflicted by champion summoned units. This is in addition to any other classifications. For example, the damage dealt by Tibbers OriginalSquare Tibbers' basic attacks and aura are both classified as "pet damage" in addition to basic attack damage and ability damage, respectively. This classification is currently only used by Rylai's Crystal Scepter item Rylai's Crystal Scepter.


Ability damage

Ability damage is the damage type inflicted by almost all abilities. Fizz OriginalSquare Fizz's Urchin Strike Urchin Strike is noteworthy for applying both basic attack damage and ability damage.
  • Ability damage will apply spell effects, including spell vamp.
  • Some abilities grant the champion bonus ability damage on their attacks. As a standard, however, most effects that trigger on a champion's basic attacks (including those sourced from an ability) deal on-hit damage.
  • Some abilities modify the champion's attacks to deal ability damage.
  • Most spell effects inflict ability damage, allowing them to trigger other spell effects (excluding itself).

Basic attack damage

Basic attack damage is the classification for the damage dealt by almost all basic attacks with the notable exceptions being a handful of champion summoned units.

  • Basic attacks will trigger on-hit effects once. Some abilities and items can increase this.
  • Physical basic attack damage will apply life steal. This means modified basic attacks that deal magic or true damage will not life steal from that damage, except for Corki OriginalSquare Corki, who will also life steal from magic damage.
  • Some abilities modify the amount of basic attack damage dealt, such as Corki OriginalSquare Corki's Hextech Munitions Hextech Munitions.

Bleed damage

Bleed damage, or damage over time (DoT), is the classification for many of the game's lesser damage over times, which are in most cases attached to a basic attack but is also applied by some spell effects.

On-hit damage

On-hit damage is the classification for the damage dealt by on-hit effects, which are effects that trigger when a basic attack hits.

Splash damage

Splash damage, or area of effect damage (AoE), is the damage type applied by some area of effects that deals damage in a defined area, either around the target or in a chosen place.

Damage Calculation

Physical and magic damage are first reduced (or amplified) by armor and magic resistance respectively before being applied to target. This can be calculated through a damage multiplier.

  • Physical damage's damage multiplier:

$ \pagecolor{Black}\color{White}{\rm Damage\ multiplier}=\begin{cases}{100 \over 100+{\it Armor}}, & {\rm if\ }{\it Armor} \geq 0\\2 - {100 \over 100 - {\it Armor}}, & {\rm otherwise}\end{cases} $

  • Magic damage's damage multiplier:

$ \pagecolor{Black}\color{White}{\rm Damage\ multiplier}=\begin{cases} {100 \over 100+{\it MR}}, & {\rm if\ }{\it MR} \geq 0\\ 2 - {100 \over 100 - {\it MR}}, & {\rm otherwise} \end{cases} $

Actual damage types

Actual damage types:

Name Description Example
Raw Execution damage - ignores shields, revives, etc. Fear Beyond Death Fear Beyond Death
Internal raw Fountain damage. As above but also ignores Invulnerability. Only Fountain
Default/Periodic Ability-based procs that don't have interactions. Things without a type default to this type, which includes splash damage. Liandry's Torment item Liandry's Torment and Tiamat item Tiamat
Proc On-hit effects. Wit's End item Wit's End
Reactive Reflected damage. Only Thornmail item Thornmail
Attack Basic attacks and some abilities. Mystic Shot Mystic Shot
Spell Most abilities. Disintegrate Disintegrate
SpellAOE As above, we currently group as "ability damage". Incinerate Incinerate
SpellPersist As above, we currently group as "ability damage". Drain Drain
Pet Some pets deal pet damage, others deal Spell/SpellPersist. Tibbers OriginalSquare Tibbers basic attacks

Physical, Magical and True are secondary types that are added to the aforementioned types to modify their interaction with resistances.

Capped Damage

Some abilities, scaling with target's health, have a capped amount of damage they can deal to a target. This is made to avoid dealing massive damage to targets with a lot of health.

  • If the ability deals enough damage (before damage reductions) to reach the cap, the ability's damage is reduced to the cap and damage reductions are then applied. This means that against a target that has negative armor or magic resistance an ability can deal damage over the cap.


  • Contrary to popular belief, life steal and spell vamp are not specific to physical and magic damage, respectively. Life steal will apply to anything classified as basic attack damage (including the magic damage from Takedown Takedown, Hextech Munitions Hextech Munitions and Infinite Duress Infinite Duress), and spell vamp will apply to anything classified as ability damage (including the physical damage from Comet Spear Comet Spear and true damage from Reckless Swing Reckless Swing).
