Once the leader of the infamous mercenary band, Boomholwer & Co., Greygore Boomhowler struck out as a solo act - no, like he actually struck out - until he found an instrument that truly spoke to him: a chain gun! Boomhowler is a Gunner class hero with great support options and strong ranged damage. In addition to being capable of making two ranged attacks a turn instead of the normal one, Boomhowler also boosts the attack stats of other heroes in your Crew near him.
