What is Tenacity in League of Legends?


Ever been stuck in place, unable to fight back when it mattered most? Those nasty crowd control (CC) effects like stuns, roots, and slows can halt your every move. Fortunately, there’s a stat that can help reduce their impact: Tenacity.


Tenacity shortens the duration of most CC effects, allowing you to maintain mobility and reaction time during crucial fights. However, it’s important to note that certain CC types—like airborne and suppression—are immune to Tenacity and always last their full duration.


How to Calculate Tenacity

Tenacity is expressed as a percentage and can be obtained through items, runes, and champion abilities. The higher the Tenacity, the less time you’ll spend helpless against enemy CC.


The formula for calculating total Tenacity is:

1 - ((1 - CC Reduction from Items/Runes) * (1 - CC Reduction from Abilities))


Example:

  • Garen’s Courage (W): 60% Tenacity
  • Legend: Tenacity Rune (fully stacked): 30% Tenacity
  • Mercury’s Treads: 20% Tenacity

Plugging these values in:

1 - ((1 - 0.20) * (1 - 0.30) * (1 - 0.60))

= 1 - (0.80 * 0.70 * 0.40)

= 1 - 0.224

= 0.776 or 77.6% Tenacity


With 77.6% Tenacity, CC effects are significantly shortened, keeping you more active in fights.
