Dragonborn's breath

When you cast this spell you exhale a 15-foot cone of magical energy. Each creature in that area must make a Constitution saving throw. On a failed save it takes 1d6 damage of the type associated with your Chromatic Ancestry. On a successful save, it takes no damage. This damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).

This spell is exclusively available to Dragonborn.
