Whisper of Shards

Whispering half remembered utterances said by your patron itself, you manifest void shards around you, that then fly towards a target in range who must make a Dexterity saving throw. A creature takes 3d10 Necrotic Damage and 3d10 force damage on a failed save, or half as much damage on a successful one.

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d10 Necrotic Damage for each slot level above 3rd.
