This is relatively minor, but worth mentioning. Here's the message when Drums of the Snake wears off:

>>The rhythmic thrum flowing through your body lingers with a fading warmth like the last rays of the setting sun.

This is the message you used to get when you stopped playing Drums, so naturally it became the "buff ending" message. The problem is that Drums used to put a buff on you that lingered after you stopped playing (so that you could actually use its bonus to do something requiring both hands), so this is actually a message originally written to indicate that your buff has not yet expired -- hence "lingering." To avoid confusion, is there any way we could get a message that's a little clearer about your buff going away? I know there used to be another message in the old spell for when your buff really had fallen off.
