I underestimated Volo...
all the while i thought him a fraught bard.
right now i'm listening to him whistling (in retrospective it should've been obvious) along with alfira and my violinist durge at the tielfling party.
he is still a fraught. but he's best bard.
Edit: i found out it's a default feature that bard whistle when no instrument is equipped.
my headcanon of volo whistling "the good the bad and the ugly" theme in front of a bewildered goblin audience (he is air-guitatring everyting else) STILL STAND
