A purple flower bloom appears within range before suddenly expanding out in a crackling spear of dark necromantic energy . Each creature in a 20-foot-radius sphere centered on that point must make a Constitution saving throw. A target takes 6d8 necrotic damage on a failed save, or half as much damage on a successful one. Plants make this save at disadvantage.

Any foliage in the area is left shriveled and dead.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd.
