Evocate limb

You evocate a limb from a creature that you killed. The limb will appear attached to the creature you touch, at the exact place you place your hand, and will become usable for said creature.

You must carry the bone(s) needed for the limb to form. The limb will be formed exactly as it was on the original creature.

It will remain attached for a week, then fall away and become dust. While attached, it behaves as another limb of the creature using it, and can be hurted.

If casted ritually together with the recipient, it can be permanent at choice.
