Shifter Fear

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

• Increase your Strength or Constitution by 1, to a maximum of 20.
• When you take the Attack action on your turn, you can replace one of your attacks with a roar, forcing each creature of your choice within 30 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 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 can use your roar a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
