Tenacity, or Crowd Control Reduction, is a stat that reduces the duration of all incoming 
crowd control status effects (disables) except 
airborne, 
drowsy, 
nearsight, 
stasis, and 
suppression.
Tenacity is a percentage, and it indicates by how much the disable's duration is reduced. Any disable's duration cannot be reduced below 0.3 seconds*. The disable's duration is calculated at the moment of application, and does not change during it if tenacity changes.
- Tenacity stacks either
multiplicatively or 
additively, depending on the combination of the effects.
Tenacity can be increased (self- or ally-sourced) and decreased (enemy-sourced) from abilities, buffs, items, runes, and summoner spells.

Decreasing tenacity[edit | edit source]
Note that tenacity can have negative values, which will cause incoming disables to last longer.
Champion Abilities[edit | edit source]
Ornn's 
Bellows Breath and 
Call of the Forge God apply 
Brittle, a unique status effect that reduces targets' tenacity by 30%.
Stacking[edit | edit source]
The tenacity stat is built up from sub-stats that internally are referred to as "modifiers" and are part of three different groups, labelled A, B, or C. Modifiers within the same group stack multiplicatively, while the different groups stack additively with each other.
Tenacity is capped at 100%.
The mathematics regarding the total tenacity is as follows:
(1 - ((1 - A1)(1 - A2)(1 - ...))) + (1 - ((1 - B1)(1 - B2)(1 - ...))) + (1 - ((1 - C1)(1 - C2)(1 - ...)))
| Source | |
|---|---|
| Group A | |
| Group B |
|
| Group C |
|
For instance, a champion has Mercury's Treads and Wit's End equipped, and they have been debuffed by Brittle's tenacity reduction from an enemy. The sum of their tenacity is calculated as follows:
- Group A Tenacity modifiers = 30% × 20%
- Group C Tenacity modifier = -30%
- Final Tenacity = (1 - ((1 - ) × (1 - )) Group A Tenacity modifiers + Group C Tenacity modifier
- = (1 - ((1 - 0.3) × (1 - 0.2)) + -0.3
- = (1 - (0.7 × 0.8)) + -0.3
- = 0.44 + -0.3 = 14%
Trivia[edit | edit source]
- Until patch V1.0.0.118, Tenacity was an unnamed effect unique to Mercury's Treads. That patch promoted the effect to a champion statistic and added three new items:
Cloak and Dagger, 
Eleisa's Miracle and 
Moonflair Spellblade (all later removed). Tenacity from multiple sources did not stack, similar to Enhanced Movement. In Season Three (2013) there was an item overhaul, named item effects were introduced, and Tenacity was reverted to an item effect. In V3.01, all sources of crowd control reduction were changed to say "Tenacity" and Tenacity was reintroduced as a champion statistic. - Until Season Three (2013), Tenacity's in-game icon was the same as the icon used for
Cho'Gath's 
Vorpal Spikes and 
Baron Nashor's passive. Between the introduction of season 3 changes and V3.01, it shared the same icon as the 
Tenacious mastery. As of V3.01, it no longer has an icon in the buff bar. - Prior to the Preseason of 2021, a website news post was made that announced that Tenacity would reduce the duration of knockups. However, the change was confirmed to have been cancelled.[1]
- Prior to his VGU in patch V11.12,
Dr. Mundo's 
Burning Agony granted himself 30% Tenacity which was additive with other "Champion Tenacity" buffs such as Brittle. - Prior to V3.04,
Singed's 
Insanity Potion granted himself 10 / 15 / 20% Tenacity. - Prior to patch V12.22,
Sunfire Aegis' Mythic passive granted 5% Tenacity per Legendary item which was additive with other "Buff Tenacity" buffs such as 
Elixir of Iron and 
Unflinching. - On patch V12.22 it became possible to reach 100% tenacity by combining Mercury's Treads (30%)
Silvermere Dawn (active) (50%) and 
Iceborn Gauntlet with 4 other legendary items (20%), which are additive with one another. Until V12.23 it was even possible to reach 120% Tenacity by including 
Mosstomper Seedling, which was also additive with these sources. - After V13.3, the highest amount of tenacity was changed to 100% since combinations of effects in different groups were made to be additive.
- Examples of combinations that can reach the cap (V13.18):
Courage and 
Cleanse [60% + 50% = 110%]- Courage, Mercury's Treads and
Legend: Tenacity [60% + (1 - 0,7 * 0,8) = 104%] - Mercury's Treads,
Breath of Life and Cleanse [30% + (1 - 0,35 * 0,5) = 112,5%] - Cleanse, Mercury's Treads and Sterak's Gage [50% + (1 - 0,7 * 0,7) = 101%]
- Examples of combinations that can reach the cap (V13.18):
| Offensive |  Ability power ·  Attack damage ·  Attack speed ·  Critical strike chance ·  Critical strike damage ·  Armor penetration ·  Magic penetration ·  Life steal ·  Omnivamp · Physical vamp ·  True damage
|
|---|---|
| Defensive |  Heal and shield power ·  Health ·  Health regeneration ·  Armor ·  Magic resistance · Tenacity ·  Slow resist
|
| Utility |  Ability haste ·  Energy ·  Energy regeneration ·  Mana ·  Mana regeneration  Movement speed ·  Basic Attack Range

Crowd controlA unit that is disabled is affected by a status effect that prevents certain actions – such as movement, attacking, casting and/or seeing–blocked, reduced or controlled.
Crowd control applied by one's self or an ally cannot be countered in any way, neither reduced in duration, resisted, nor removed unless special cased to do so.
Airborne
summoner spells 
Flash, 
Teleport, 
Hexflash, and 
Mark / 
Dash.Airborne is an
immobilizing effect.
| Interrupts: | Interrupts attack windups (excluding  uncancellable windups), and all  channeled and charged abilities. The accompanying displacement overrides all other previous displacements, including dashes and other airborne effects.
|
|---|---|
| Reduction: | The duration of airborne and its forced movement execution time is unaffected by  Tenacity.
|
| Resist: | Resisted by  crowd control immunity,  displacement immunity, and  Dr. Mundo's  Goes Where He Pleases.
|
| Removal: | The forced movement that is applied alongside airborne effects cannot be removed by cleanses, which innately disables attacking and moving and can be overridden by dashing, blinking or  lunging.  Cleansing effects, with the exceptions of  Milio's Breath of Life, Cleanse,  Mikael's Blessing, and  Quicksilver, remove the airborne status effect.
|
Crowd control applied by one's self or an ally cannot be countered in any way, neither reduced in duration, resisted, nor removed unless special cased to do so.
Drowsy
slowed, and afterwards will fall 
asleep.
Removing drowsy or being displacement immune or immune to crowd control at its end will prevent sleep from occurring.
| Interrupts: | Does not interrupt any actions. |
|---|---|
| Reduction: | The duration is unaffected by Tenacity.
|
| Resist: | Resisted by crowd control immunity.
|
| Removal: | Removed by Cleanses.
|
Slow resist, 
slow immunity and slow removals (i.e - 
Decisive Strike) can be used to (respectively) weaken, prevent or remove the associated slow, however, it does not prevent from falling asleep after the duration. Tenacity gained while drowsy will still affect the duration of the sleep.
Nearsight
sight radius reduced and cannot see beyond their sight radius.
While nearsighted, units cannot reveal stealthed 
wards or 
traps. Nearsighted units lose vision of all their allies as well as all external sources of vision (including from wards or abilities). This prevents 
unit-targeted effects, including basic attacks, from being used outside of the unit's reduced sight radius.
True sight and 
unobstructed vision do not bypass the vision blocked by nearsight.
Sources of nearsight do not stack with each other; only the application with the greatest sight reduction will take effect.
| Interrupts: | Interrupts target commands if the nearsighted unit's target is outside of their new vision area and prevents  automatic target acquisition.
|
|---|---|
| Reduction: | The duration is unaffected by Tenacity.
|
| Resist: | Resisted by crowd control immunity with the exceptions of  Fiora's  Riposte and  Morgana's  Black Shield.
|
| Removal: | Removed by Cleanses with the exceptions of Cleanse and Mikael's Blessing.
|
Crowd control applied by one's self or an ally cannot be countered in any way, neither reduced in duration, resisted, nor removed unless special cased to do so.
Stasis summoner spell for the duration, while also being 
invulnerable and 
untargetable.Stasis is an
immobilizing effect.
| Interrupts: | Interrupts attack windups (excluding uncancellable windups), all channeled and charged abilities and all dashes and displacements. Units that are being knocked up will be placed on the ground, but aren't  knocked down (the airborne status is not removed in this case).
|
|---|---|
| Reduction: | The duration is unaffected by Tenacity.
|
| Resist: | Resisted by crowd control immunity, displacement immunity, and Dr. Mundo's Goes Where He Pleases.  Epic monsters and  turrets are special cased to be affected by stasis despite them being crowd control immune.
|
| Removal: | Cannot be removed by any means (except through  death), and will prevent the activation of abilities that would usually remove crowd control effects. Quicksilver will either be placed on a short cooldown, remain usable, or become disabled.
|
Crowd control applied by one's self or an ally cannot be countered in any way, neither reduced in duration, resisted, nor removed unless special cased to do so.
Suppression summoner spell for the duration.Suppression is an
immobilizing effect.
| Interrupts: | Interrupts attack windups (excluding uncancellable windups) and all channeled and charged abilities.
|
|---|---|
| Reduction: | The duration is unaffected by Tenacity.
|
| Resist: | Resisted by crowd control immunity and Dr. Mundo's Goes Where He Pleases.
|
| Removal: | Removed by Cleanses with the exceptions of Cleanse and Mikael's Blessing.

immobilized.
Tenacity (or Crowd Control Reduction) is a stat that reduces the duration of all incoming crowd control effects except displacements, drowsy, nearsight, stasis, and suppression.
If tenacity is reduced below 0, the crowd control duration increases.
