Crystal Burst (Andy)

 "A sorcery of the Crystal Cadre, a group of sorcerers who perused the knowledge of stone. the secrets locked in the faint cogitation of the Crystalians."

You create a rapidly expanding chunk of glintstone. As the crystal expands fragments begin to shoot off in a 10ft cone in front of you. Each creature needs to make a dexterity saving throw or take 1d8 magical piercing.

Charge

If you use your bonus action in tandem with the spell you instead deal 1d10 magical piercing.

At higher levels the damage increases. Once at 5th, 11th, and 17th level.

*Note from creator. The (Andy) is in reference to a character that created this, be sure to talk to your dm if you can use these as they are incredibly untested!
