Bloody Splash

You shake the ground as large spouts of blood start to appear around an area of your choosing. 

Each creature in a 25-foot radius sphere centered on the point of choosing must make a Dexterity saving throw. A creature takes 8d6 necrotic damage on a failed save, or half as much damage on a successful save.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the base damage increases by 1d6 for each slot level above 4th.
