Song of Heroes

Perform a legendary anthem of courage. Creatures of your choice in the emanation that can hear you gain one Heroic Inspiration die, a d12, at the start of each of their turns. A creature may spend this die on an attack roll, ability check, saving throw, weapon damage roll, or AC against one attack. While affected, creatures are immune to being frightened and have advantage on saving throws against being charmed.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
