Curse of Sanguine Explosion

You point to a creature you can see, the target must succeed a Constitution saving throw or be cursed, this spell only works if the target has blood.

On a failed save every time the target takes damage the blood vessels and organs in their body rupture causing them to take an additional 2d8 Necrotic damage. If the target dies while afflicted by the curse their body explodes damaging everyone within a 15 ft sphere of them dealing 6d8 Necrotic damage.
