Also, how do you know when you've lagged them a little bit? Seems to be the main song of bards, and some say it lags.

I gather it also skews heavily towards the epic repertoire, as far as the lag is concerned.

The vibrato helpfile says "bolder styles". That includes epic for sure, but may also include comedic. Tragic/romantic, to me, don't seem to fit the definition of "bolder style".

It has the potential to lag. Meaning, it doesn't lag you every time. There is no way of knowing. Meaning there is no echo when it lags. When it lags, it is roughly the same as trip. It is never more and never less if it does lag. If it doesn't lag, it doesn't lag at all. There is no partial lag from vibrato.

Ok, thanks. Didn't know. I was hit by it one time, and could flee instantly, but the next time I was lagged a bit.
