Holy lance is a cleric spell. The invasion of the Orcish hordes has necessitated our divining a method to protect not only ourselves, but the whole of the people of Azeroth, as well. The use of physical violence is not the calling of our order, but each force must be met with an equal force for the balance of good and evil to be preserved. As the archangels took up swords of light to defend the heavens, so must we take up holy arms to defend our lands. The pure essence of the casters heart, mind, and soul strikes out to defend him from threat, and enters into the soul of the target. This is especially effective against the Orcs because of their dark and evil origins.
