When angered, you can radiate menace. You gain the following benefits:

• Increase your Strength, Constitution, or Charisma score by 1, to a maximum of 20.
• You project a fearsome 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 on the save 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.
• You may use this ability up to three times. You regain one use upon a short rest, and all three upon a long rest. At fifth level, you gain an additional use, and another at fifteenth level.
• By expending a second use, you may double the range of the feat, increase the DC to 10, and add your strength modifier. At tenth level, you gain the ability to expend multiple extra uses, and at twentieth level, you may apply one expenditure for free.
