Crystal Surge

You summon a surge of elemental crystal shards that burst outward.

A creature of your choice within range must make a Dexterity saving throw or take 1d4 piercing and 1d4 of a random elemental damage type (1. fire, 2. cold, 3. lightning, 4. acid, or 5.  thunder). Roll a 1d6 for the damage type on a 6 you choose. 

Scaling:

• 5th Level: Damage increases to 2d4 + 2d4 and you can roll a 1d6 for the piercing damage to be one of the elements. 
• 11th Level: Damage increases to 3d4 + 3d4 and you can choose what the elemental damage is. 
• 17th Level: Damage increases to 4d4 + 4d4 and you choose what the elemental damage for both damage rolls.
