Show your Vanity!! (All Races!)

Excuse me - that flute right there. It's for bard, right? Could you tell me the name of it? ;O

JumperX is right, it's one of the cross-role 'song' spells that not only BRD, but MCH have. (I've no idea if MCH looks the same while casting though.)

The one I used in that screenshot is Peloton but Tactician and Refresh both use the flute animation, just with different color of flashy lights accompanying it.
