As a Bonus Action, you can strike terror into others with your menacing presence and primal power. When you do so, each creature of your choice in a 30-foot Emanation originating from you must make a Wisdom saving throw (DC 8 plus your Strength modifier and Proficiency Bonus). On a failed save, a creature has the Frightened condition for 1 minute. At the end of each of the Frightened creature’s turns, the creature repeats the save, ending the effect on itself on a success.
Once you use this feature, you can’t use it again until you finish a Long Rest unless you expend a use of your Rage (no action required) to restore your use of it.
