So, I realize that Shadow has many offensive items, but when it comes to defense he really doesn't have much. Soooooooooooooo what I am looking for is a small crystal that I can place on my bow, any bow or weapon I choose really, that when Black Shadow activates it through touch the crystal can deflect the attack by creating what appears to be a blue forcefield that looks something like this:



Let's say it can block any attack, projectile or melee. How much would this item cost? Same for if just projectile or just melee.
