Burning Wave

You conjure a surge of searing flames that rolls through the air toward a point you can see within range. Choose up to two creatures that are no more than 5 feet apart. Each creature must make a Dexterity saving throw, taking 1d6 fire damage on a failed save, or avoiding damage on a successful one.

This spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
