Death Ripple

A ripple of dark energy originates from a point you can see within range. All creatures within a 30-foot radius of that point must make a Wisdom saving throw. On a failed save, a creature takes 8d8 necrotic damage, or half as much on a successful save. On a failed save, a creature is also knocked prone. Creatures that are not considered living, such as Undead or Constructs, are unaffected by this spell. If you cast this spell again originating from the same point less than 1 minute after the first casting, the radius is 60 feet instead.

At Higher Levels: When cast using a spell slot above 5th level, this spell deals an additional 1d8 necrotic damage for each slot level above 5th.
