Magnetic Projectile

By quickly reversing the polarity on a portion of your magnetic foot orb, you can launch items attached to you at your enemies. You gain a magnetic projectile unarmed attack in the sling weapon group with a range increment of 30 feet that deals 1d4 bludgeoning, piercing, or slashing damage—as appropriate for the object you hurled. You must have a metallic object of at least light Bulk attached to your foot orb as ammunition for this attack, but no specific traits or magic properties of the thrown item affect the attack or the damage.
