Boon of Dhorlot - Breath weapon

Once per long rest you can use your action to exhale destructive energy in a 5 ft. wide, 30 ft. long area. Each creature in that area must make a DC 14 Dexterity saving throw, taking 2d6 acid damage on a failed save, or half as much damage on a successful one.

This feat is not available until you find a way to learn it during your adventures.
