Gray Energy (Weapon Property) A strange counterpart to brilliant energy weapons, a gray energy weapon has its significant portion – such as its blade, axe head, or arrowhead – transformed into a dull gray energy that sheds barely enough light to illuminate itself. A gray energy weapon is disruptive to nonliving material but ignores living matter. Against objects, undead, and constructs made of nonliving materials, it ignores hardness and natural armor (armor, Dexterity, deflection, dodge, and other such bonuses still apply.). Bows, crossbows, and slings cannot be crafted with this ability. A weapon cannot have both brilliant and gray energy weapon properties. Caster Level: 10th. Prerequisites: Craft Magic Arms and Armor, gaseous form, deeper darkness. Market Price: +2 bonus.
