Blackwings has 'singing' bracketed as a keyword ('infernal [singing]'). I have yet to get any response using various phrases with 'singing' in them. Has anyone succeeded in getting a response to it? Or was that just a clue to use singing and the epic? I just sang dots and used piercers, because Blackwings said "pierce", even though it wasn't a keyword. The piercers seemed to do more damage than my 1HBs, even though the piercers are lower damage weapons).
