"Sacred" can't be anything but a Darkest-Hour song – possibly to the extent that using it in anything but absolute desperation will somehow cause the situation to worsen.
Hmm… taking a page from more traditional Bards, Doug and allies (or maybe just his allies, leaving Doug himself immobile) within AoE are given a massive boost to confidence and determination, with a commensurate increase in physical/metaphysical abilities? Or possibly a "pure channelling" song, gathering up available ambient mana, tapping nearby ley lines, nodes, and tethers, and making all that and much of his own reserves available to an allied spellcaster? No, no, it should definitely involve granting Heroic Resolve to allies in order to turn them into Determinators.
