Bone Shield

This Spell is a Rare Spell these type of spell you need to find or unlock from a spell scroll or some other Source(optional rule)

You create Twelve bones that spin and float around you. Each with an innate will to block attacks for you. Each time you are attacked, the bones will block, and be destroyed; this happens even if an attack roll would miss you. As long as at least one bone remains, you have resistance against slashing, bludgeoning, and piercing damage. Whenever an attack that deals one of those types of damage hits you, one bone is destroyed. If an attack that is blocked is a critical, it instead breaks 2 bones.
