Debuff

For a full list of detrimental effects and icons, see Category:Detrimental Effects.

Debuffs have borders while Passives do not.

A Debuff is a detrimental effect that negatively impacts the Champion suffering from the Debuff, and is normally red in color. Debuffs are separated from passive effects in that they always have a border, and can be removed by Purify, Tenacity as well as Cleanse. Damaging Debuffs like Bleed and Shock deal damage over time, while non-Damaging Debuffs like Stun and Armor Break do not.

A Debuff is affected by three factors:

• Potency: The strength of the Debuff; usually represented by a numerical value, or as a percentage for some Non-Damaging Debuffs.
• Duration: The length of the Debuff; usually represented in seconds.
• Ability Accuracy: The chance for the Debuff to trigger; usually represented as a percentage.

E.g. - 70% chance to Armor Break, removing 1 Armor Up Buff and reducing Armor Rating by 2100 for 8 seconds.
- 70% is the Ability Accuracy, 2100 is the Potency, and 8 seconds is the Duration.
