Titan's Corpse Explosion

You point at a medium-sized corpse or larger you can see within range, the corpse then violently explodes in a shower of blood, bone, and flesh.

Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 7d6 necrotic damage and is knocked prone on a failed save, or half as much damage on a successful one. Once a corpse explodes it may not be selected again as a valid target for this spell.

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 and the radius of the blast by 5ft, for each slot level above 3rd. When using a 5th level spell slot, one additional corpse in the range may also be selected to explode as well. When using a 7th level spell slot, three additional corpses in the range may also be selected to explode as well. When using a 9th level spell slot, five additional corpses in the range may also be selected to explode as well. The same corpses may not be selected multiple times.
