Prerequisite: Dragonborn (gold)

Instead of exhaling destructive energy, you can expend a use of your Breath Weapon trait to exhale weakening gas, forcing each creature within a 15-foot cone to make a Strength saving throw (DC 8 + your proficiency bonus + your Constitution modifier). On a failed save, a creature has disadvantage on Strength-based attack rolls, Strength checks, and Strength saving throws for 1 minute. The creature can repeat the saving throw at the end of each of its turns, ending the effect on itself with a successful save. The range of this gas breath increases to a 20-foot cone at 6th level, a 30-foot cone at 11th, and a 60-foot cone at 16th level.
