Spined Shield: This +1 heavy steel shield is covered in spines. It acts as a normal spiked shield. On command up to three times per day, the shield’s wearer can fire one of the shield’s spines. A fired spine has a +1 enhancement bonus, a range increment of 120 feet, and deals 1d10 points of damage (19–20/x2). Fired spines regenerate each day.
