You summon draconic power to gain a breath weapon. When you cast dragon breath, you can immediately exhale a cone or line of elemental energy, depending on the type of dragon you select. While the spell remains active, roll a d6 at the start of your turn. On a roll of 5 or 6, you can take a bonus action that turn to use the breath weapon again. When you cast the spell, choose one of the dragon types listed below. Your choice determines the affected area and the damage of the breath attack for the spell’s duration.
