Tenacity[]
Tenacity is a mechanic that reduces the duration of crowd control effects. It does not affect the potency/strength of the effect. Tenacity will not stack with other sources of Tenacity.
Tenacity works on: Blind, Forced Actions (Charm, Terrify, Fear and Taunt), Pacify, Silence, Slow and Stun.
Tenacity does not work on: Airborne (Knockback, Knockup and Pull), Attack Speed Reduction and Suppression.
Tenacity reduces the duration of Crowd Control effects by a percentage. X amount of Tenacity will grant X% reduced Crowd Control duration.
Having 35 Tenacity results in 35% reduced Crowd Control duration.
When multiple source of items have tenacity, the most powerful relevant effect applying to that statistic is the one that takes effect.
