Shardfall

7-level Conjuration

You call down shards of crystalline magic from beyond this realm. For the duration, any creature you choose that starts its turn within 90 feet of you takes 1d6 slashing damage as it is hit with tiny razor-sharp crystals.   As a part of your action to cast the spell, or as an action on subsequent turns, you can bring down a shard of crystalline energy at a point that you can see within 90 feet. Each creature within a 10-foot radius sphere of the shard when it falls must succeed on a Dexterity saving throw or take 6d10 force damage.
