Discharge

Blasting enemies with waves of frost and lightning isn't just a talent reserved for pure weavers of magic. With the Discharge skill, any combatant can channel accumulated charges into a swirling tower of seething energy. The composition of the blast varies depending on the type of charges consumed, dealing cold with Frenzy, fire from Endurance, and lightning from Power Charge. Regardless of the charge type, surrounding foes are blown to bits.

Description on the official Path of Exile website

Discharge is a spell that unleashes all of the player's charges (frenzy charges, power charges and endurance charges) and deals elemental damage in an area around him.

Skill functions and interactions

• Area of effect: all damage from expended charges is dealt simultaneously within a radius centered around the caster. This radius can be altered with area of effect modifiers. Discharge has a target cap of 30 targets, meaning that even if Discharge's area of effect covers more than 30 monsters, only 30 of them would be hit.

• Charge bonuses: any bonuses granted from the charges that are being expended will be actively applied to that cast of Discharge. For example, expending three Power Charges and three Frenzy Charges will cause that cast of Discharge to have +150% increased chance to crit, deal 12% more damage, and the cast time will be increased by 12%. Once Discharge is finished casting, charge bonuses will no longer apply.

• Charge-gaining effects: this skill will apply charge-gaining effects after the loss of the charges consumed to cast it. For example, critical hits while wearing the Voll's ProtectorVoll's Protector

  Inner ConvictionAlthough a great leader during the war,
  Voll proved disastrous in times of peace. 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), regardless of whether the previous cast consumed any power charges. 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.
