~Ascendant Obliteration~

You unleash a rift of hungry darkness that screams across the battlefield. A beam of annihilating shadow erupts from your hand in a 10-foot-wide, 120-foot-long line.

Each creature in the line must make a Constitution saving throw. A creature takes [roll]12d10[/roll] necrotic damage on a failed save, or half as much on a success.

Creatures reduced to 0 hit points by this spell are instantly vaporized into crimson mist, leaving behind only nonmagical equipment.

This damage ignores resistance to necrotic damage. Creatures immune to necrotic damage take half damage instead.
