Discharge

Discharge is a spell that consumes all of the player's charges (specifically frenzy charges, power charges and endurance charges) to deal elemental damage per charge consumed in an area around them.

Skill functions and interactions

• Area of effect: All damage from expended charges is dealt simultaneously within an area centered on the caster. This area can be altered with area of effect modifiers and the number of charges used.

• Charge bonuses: Any bonuses granted by charges that are being consumed will be applied to that cast of Discharge. For example, consuming three Power Charges will still cause that cast of Discharge to have +120% increased chance to critically strike. Once Discharge is finished casting, the charges are gone and their bonuses will no longer apply.

• Charge gain: This skill will apply charge-gaining effects after the loss of the charges consumed to cast it. For example, critical hits while wearing the armor will cause a number of Power Charges to remain after casting equal to the number of enemies hit (up to the character's charge cap). The same effect applies to Frenzy Charges gained from kills under the buff or charge-gaining effects.

The gem gives a chance to gain only one power charge after every cast, regardless of the number of monsters hit.

• Minimum charges: Discharge needs to remove charges for its damage to be increased, and increases to Minimum Charges, such as the +1 to Minimum Endurance Charges from Disciple of the Unyielding, don't allow those charges to be removed. Therefore increasing minimum charges will decrease the damage of discharge as the player is effectively reducing their maximum consumable charges.
• Cooldown: Discharge has a cooldown of 2 seconds, which can be modified by sources such as . The unique threshold jewel sets the cooldown to 250ms, which overrides all other cooldowns and cannot be further modified by any sources.

• : Discharge cannot be linked to Spell Totem Support.
