Impale

Impale (displayed as Impaled in the status icon) is a debuff that deals additional physical damage to the affected target each time it is hit.

Mechanics

When a hit applies impale to a target, 10% of that hit's physical damage is recorded before any damage mitigation is applied. Impale deals the recorded damage to that target each time it is hit. Impale remains in effect for 8 seconds or until the maximum number of hits is reached. By default, impale lasts for five hits. A target may have multiple impale effects on it at once, all of which deal damage to that target each time it is hit.

The damage dealt by impale is considered reflected damage. The source of the reflected damage is the impale debuff; there is no interaction with effects that pertain to damage you reflect, as seen on [[Crown of the Pale King.

Damage Calculation

Note: All calculations below assume 100% impale chance to make them simple. They also assume solo gameplay. No impale damage is done on the first hit to enemies. The second hit does 10% reflected damage. The third hit does 20%. Etc. This damage is capped at the total number of impales you land per hit multiplied by 10. Therefore 5 impales is 50% and 7 is 70%. This damage is then further multiplied by increased impale effect.

Example: Champion with plus 1 max impales, level 20 impale support with 20% quality and 20% impale effect from passives.

• Maximum impale damage begins at 7 hits. The base is 60% reflected damage.
• All impale effect modifiers include 59% from the gem and 20% from passives = 79%.
• Final damage is (60 x 1.79) = 107% of the damage of the hit in impale damage.
• The slower the attack speed of the character and the less hits per attack, the longer it will take to start doing maximum impale damage per hit.

The Impaler causes impale damage to be calculated differently. Depending on the individual build this keystone may increase or decrease the impale damage.
