Electricity from the stun guns quickly over-saturated Errald, arching wildly from his armor to his flesh to his sword and back to his armor. Immune to the massive burns caused by the free electrons as they raced through all his important fleshy bits the net result was most similar to a seizure, a violent, sword-wielding, electric seizure. 

The shear force of the attack flung Errald back ten feet, his sword and armor smoking, spot-welded, and partially melted. His nervous system while not technically damaged felt that it should be. it took a moment to let his heart make sure it was in fact still beating, finding to his great relief that it was he retaliated with fire.
