Mask: Protagonist

When you roll initiative while wearing this mask, you gain temporary hit points equal to half your bard level (rounded up). As a bonus action, you can mark a creature as your antagonist for 1 minute. For the duration, you have advantage on ability checks involving your antagonist. Additionally, when you see your antagonist make an attack, you can use your reaction and expend a use of your Bardic Inspiration, rolling a Bardic Inspiration die to reduce the attack roll by the number rolled on the die.
