Terror of the Black Dragon

You possess the terrifying aura of the black chromatic dragons, granting you the following benefits:

• Increase your Constitution score by 1, to a maximum of 20.
• Instead of exhaling destructive energy, you can expend a use of your Breath Weapon trait to roar, forcing each creature of your choice within 10 feet of you to make a Wisdom saving throw (DC 8 + your proficiency bonus + your Constitution modifier). A target automatically succeeds on the save if it can’t hear or see you. On a failed save, a target becomes frightened of you until the end of their next turn.
