Dragon Fear (XGE)

Prerequisite: Dragonborn
When angered, you radiate menace. You gain the following benefits:
• Increase your Strength, Constitution or Charisma score by 1, up 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 30 feet of you to make a Wisdom saving throw (DC 8 + your proficiency bonus + your Charisma modifier). A target automatically succeeds if it can’t hear or see you. On a failed save, a target becomes frightened of you for 1 minute. If the frightened target takes any damage, it can repeat the saving throw, ending the effect on itself on a success.
