Shock is an elemental ailment associated with lightning that causes the affected target to take increased damage from all sources.

A hit of damage that has a X% chance to shock is capable of inflicting shock. Critical strikes always inflict shock regardless of their chance to shock. Modifiers to chance to shock can be found on some gems, equipment, and the passive skill tree. By default, only lightning damage is able to inflict shock. Some skill effects and modifiers, such as Shocked Ground and Summon Skitterbots, apply shock without dealing damage.

The base duration of shock is 2 seconds and its effect is determined based on to the amount of Lightning damage dealt relative to the enemy’s ailment threshold. Shock’s effect is capped at 50%. Shock’s minimum effect is 5%; any shock of lesser effect than that is discarded. The effect of shock is calculated using the following formula:

E=1/2*({D T})^{0.4}*(1+M)

where D is the lightning damage dealt, T is the enemy’s ailment threshold, and M is the sum of the attacker’s increases to the effect of shock (normally 0%).

In the great majority of cases, a monster’s ailment threshold is equal to its maximum life. It primarily differs for especially high-life monsters (such as The Shaper), where the threshold is reduced to allow ailments to be applied with hits that wouldn’t ordinarily reach the required life thresholds. Playtesting estimates the ailment threshold on Sirus, the Awakener of Worlds to be 25million damage, or approximately 35% of boss life.

In-depth mechanics

Some modifiers such as Shocking Conflux or the modifiers found on The Three Dragons and Voltaxic Rift can change which damage types are able to inflict shock. If the player is able to shock with multiple different damage types, the shock’s effect is determined by the total damage dealt by all applicable damage types.

Some modifiers, such as the one found on Voltaxic Rift, can raise the maximum effect of shock beyond 50%.

Modifiers to shock effect, such as X% increased Effect of Shock, apply to the effect of the shock before the minimum or maximum effect is enforced. This means that increases to the effect of shock effectively reduce the amount of damage needed to apply both a minimum and a maximum shock. For example, a total of 100% increased Effect of Shock would reduce required the amount of damage dealt to apply a minumum effect shock to 0.06% of the enemy’s ailment threshold, and reduce the required damage dealt for a maximum shock to 17.68%.

Unless otherwise specified, all sources of shock that apply without dealing damage have a base effect of 15% increased damage taken and scale with any modifiers to shock effectiveness. Some examples of shocks that apply without dealing damage are Shocked Ground, Summon Skitterbots, and Vessel of Vinktar.

The shock ailment is applied after the hit (not before), because the magnitude of the shock is based on damage dealt.
