As a Bonus Action, you can expend one Superiority Die to bolster the resolve of a companion. Choose an ally of yours within 30 feet of yourself who can see or hear you. That creature gains [Temporary Hit Points](https://www.dndbeyond.com/sources/dnd/free-rules/rules-glossary#TemporaryHitPoints) equal to the Superiority Die roll plus half your Fighter level (round down).
