The Final Bell

A bright green streak flashes from your pointing finger to a target you choose within range and must make a Wisdom saving throw. The target takes 6d6 (8d6 if the target is undead) necrotic damage on a failed save, or half as much on a successful one. The damage ignores necrotic resistance and immunity.

If the target is brought to 0 health by the damage, it erupts in an explosion of teeth, bones, and guts. Each creature in a 20-foot-radius sphere around the target takes 4d6 piercing damage.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
