Circle of Death 5.5e 2024 vs. 5e 2014 edition differences

Both versions deal 8d8 necrotic damage on a failed save, increasing by 2d8 per slot level above 6th. The 2024 version specifies "Negative energy" and "Sphere" with hyphenation, but these are stylistic. No significant mechanical differences are present.
