Amending Flesh

You imbue the needle to stitch and repair freshly made wounds on the body of a creature you touch. For the duration of the spell, each time the target takes damage, roll 2d4 and reduce the damage it takes by the result. When the spell ends, a creature who was under this spell's effects can choose whether or not the scars left by the stitching fade away or remain as if freshly healed yet still noticeable.
