Rangeblade

As you touch the weapon, it takes on a ghostly, ethereal, gray hue.

One melee weapon touched by you takes on a ghostly, ethereal gray hue. For the duration of the spell, the wielder of the weapon can strike opponents at a distance, just as if he was standing directly next to them. The maximum range for attacks with the rangeblade is 5 ft. + 5 ft. per 2 caster levels. Creatures struck by the rangeblade see a faded, ghostly image of the weapon strike them, but the damage dealt to them is real. A rangeblade threatens no area and cannot provide a flanking bonus. This spell does not grant the wielder proficiency in the weapon.
