Shields
You can use shields in the same crafting recepies as above just replace the totem with a shield. (It will remove the banner pattern if there is one)
There is one catch thou, the shield will get curse of vanishing on it. So you will lose it when you die. But as a bonus the shield is now unbrakable.
