Breath of the Elements

Once per long rest, when you use your Dragonborn Breath Weapon, you can choose another element from a different dragonborn ancestor as your breath weapon instead of the one granted by your Dragonborn Ancestry. You must choose from the elements granted by the type of dragonborn ancestry you have, i.e. metallic for silver dragonborn, or chromatic for blue dragonborn.

At higher levels: 2 uses per long rest at level 11, and 3 uses per long rest at level 17

Below is a list of available elements from their dragonborn ancestors.
