Boom.
There was a loud bang from the Horadric Malus when it made contact with Wizard Malon's body. Abel had Malon in the blacksmith workshop as he created countless sparks over the runes on his body. The Horadric Malus was a tool blessed with the power to enhance and manipulate all sorts of metals' properties. It was not meant for attacking someone at all, but this was Wizard Malon that Abel was fighting here.
Abel made sure of something when he saw the countless sparks that were on the Horadric Malus. There was only one way to deal any damage to Wizard Malus, and that was to make sure that there wasn't a trace of energy supplied to it.
