Choose a point you can see within 60 feet. A cloud of cloud of swirling, jagged, ruby shards appears at that point and out to a radius of 10 feet. Any creature that starts its turn in this ruby shard cloud, or enters the spell's area for the first time on a turn, must make a Dexterity saving throw. On a fail they take 3d8 piercing damage or half that on a success.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.
