Don't have time to do them all but the horn is:
Additional song effect +1, all songs +3
Increases song duration for party members to 15 minutes
W A T
That's crazy, *** them >_>
Sacrifice +1 song power from Gjallarhorn for longer songs sounds neato when you're feeling lazy. Even if you get stronger songs by being willing to sing more often (and like... not THAT much more often if you have Carn).
But so many questions... Troubadour work to increase that 15min duration? Carnwenhan? Other song duration gear?
And annoyances: the natural law of Vana'diel dictates that you get those super long buffs up and DDs are going to be even MORE likely to die instantly. And Honor March won't work with this so you'll still have ONE song with oddball duration. Bah.
I'm thinking it's probably gonna be a reward somewhere during the new story content at some point.
Yeah, hard for me to imagine they'd lock something like this ONLY behind a limited Bonanza. Maybe introduce it there first, but why wouldn't they add this to the Voracious Resurgence stuff or some future event?
