Bleeding Heart

You point at a creature and squeeze the punctured heart, and it magically begins to seep blood. At the same time, the target creatures heart, or similar vital organ(s), begins to tear open and seep blood. The target creature must make a Constitution saving throw or remove 1d2 from their Constitution score. On three successful saves, the spell ends. On a failed first save, the target becomes weakened by their now failing heart, and their injuries will bleed more profusely. Whenever the target takes damage, it takes an additional 2d6 necrotic damage as blood pours from the wounds. When the target repeats the saving throw, on a failure, they will take another 1d2 Constitution damage. If the target creatures Constitution score is reduced below 15, and it's Constitution score wasn't already below 15 when the spell was cast, the creature takes a level of exhaustion. If the target creatures Constitution score is reduced below 10, and it's Constitution score wasn't already below 10 when the spell was cast, the creature takes a level of exhaustion. If the target creatures Constitution score reaches 0, the creature dies.
