The description in the Captain's Log is as follows: Steal life from enemies with every melee hit. When worn and activated, one life point is restored for every 15 points of damage dealt. This is about 6.67% of damage done, or a little more than the Vampyrism aura. The effect stacks with the Vampyrism aura and Soul Split. This effect will only work with melee attacks; ranged and magic attacks will not be affected. The scrimshaw has a cap of 200 life points healed per hit.
