Energy Wave

Any creature within a 50ft line must make a DEX save. On a failed save the target takes 1d8 radiant damage. On a success they take half damage. If the creature ends its turn within the beam they must make the DEX save and take damage. The energy beam is sustained until you lose concentration or use your bonus action to end the spell. 

The power building and the air around you blowing away, you release a basic but effective blast of energy !
