>Q: Why is there no Icon for the Bard Mana Song (Cassindra's Chorus of
>Clarity)?
>
>A: There are different types of Bard Songs. Most Bard Songs leave an icon
>on your character because the song has a duration - usually 5 to 15
>seconds. Each time the Bard sings the song she renews the duration - this
>means that a Bard who continues to sing the song can potentially keep the
>song effect going indefinitely.

>Some Bard songs do not have durations - you receive the effect when the
>Bard sings it, but will not get another "dose" until she sings it again.
>Cassindra's Chorus of Clarity (the mana song) is one of these songs - it
>does not have an actual duration, so you don't get an icon on your screen.
