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.
