Diamond Shards

You hold your palm out with a diamond on it. As you start casting the spell the diamond lifts off your hand and hovers a few inches off your hand as it starts to spin with intense magical energies and points at the target at which you are about to unleash it at, you pull your other hand far back and then suddenly thrust it forward with magical energies propelling the diamond forward towards your target.

The diamond rockets forth towards the point of impact at which point it explodes into a massive blast of sharp diamond shards ripping through everything in their path. Each creature in a 30-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 10d10 magical piercing damage on a failed save, or half as much damage on a successful one. After the diamond shards deal their damage the magical energies that propelled them consume them and make them vanish from existence.

Objects in the area are torn to shreds.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher and use a higher value diamond, the damage increases by 2d10 for each slot level above 5th.
