Weeping Wounds

You open the wounds on one creature you can see within range. For the duration of the spell, the targeted creature must make a Constitution saving throw at the start of each of its turns if it is not at full hit points. If the saving throw fails, it takes 3d6 necrotic damage as its wounds tear open and bleed profusely. The affected creature or an adjacent ally can use an action to make a Wisdom (Medicine) check against your spell save DC; a successful check ends the spell.
