Enchant Creature

Your magic empowers a small creature friendly to you. Touch a Medium or smaller beast with a challenge rating of 3 or lower. You choose a damage type (fire, acid, lightning, cold, poison), when the enchanted creature makes an attack, add an extra d6 of the chosen damage type. 

When cast at 3rd level or higher, the spell's range becomes 30 ft and the spell's damage becomes 2d6.
