The Escalated Bard (2016)

From publisher blurb:

Compatible with the 13th Age Roleplaying Game. More than a minstrel! With The Escalated Bard, your character gets new talents, backgrounds, and uniques, plus the battle cries, songs, and spells you need to bring combat to a satisfying crescendo. With magic items to equip your bard and new abilities like Soothsayer, Rewrite History, and Don't Quit on Me!, you’ll be both a master of manipulation and a virtuoso of violence. Your bard won't be comic relief — you'll be a force to be reckoned with!
