Form of the Dread Captain

You manifest an aspect of the dread captain within you. As a bonus action, you transform for 1 minute.

You gain the following benefits while transformed: You gain temporary hit points equal to 1d10 + your character level. Once during each of your turns, when you hit a creature with an attack roll, you can force it to make a Wisdom saving throw, and if the saving throw fails, the target is frightened of you until the end of your next turn. You are immune to the frightened condition.

You can transform a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
