Couple things I've learned about the invisibility song.

1) The effect does not "linger" if your party members move out
of range like other bard songs do. When they move out of
range, they immediately blink into sight. This seriously
decreases its usefulness for group movement and corpse
recovery.

2) If one of your party members blinks into sight and is
attacked, then moves back into the song's influence, the next
song tick the mobs will start attacking you even though you
are still invisible. Your song helped someone being attacked,
so they will now attack you, invisibile or not.

3) My friends were telling me that the song was canceling
their invisibility to undead.

In short, the song is probably only useful in solo play, and
if your group is not moving. Disappointing to say the least.
Anyone know if it's intended to be this way? Perhaps we could
petition to get (1) fixed. The effect does "linger" with you
for two ticks if you stop singing.
