I snipped out the discord portion to build a hybrid that would disco a Cu on a boat - then use the bard mastery (trib?) on it.
One thing about doing it this way, when you invis/hide to break provo they will sometimes reveal you. That's because the bard spell is an attack and the targets have aggro'd you.
I don't think I'd recommend this hybrid version I used. I could write in a timer and recast invis if revealed, but since I was just afk training during the day I wasn't really concerned about time.
Now, on to provo.... heh.
