Chaos Spiral

A spiraling vortex of unstable magical energy erupts at a point you choose within range, lashing out at creatures with chaotic elemental force. Choose a point in a 30-foot cone radius. Each creature in that area must make a Dexterity saving throw. 

On a failed save, a creature takes 2d8 damage and suffers one additional effect based on the type of elemental surge. On a successful save, the creature takes half damage and suffers no additional effect.

Roll a d8 to determine the damage types and additional effect:
