Ringing Leaf

Source: Western Reach sea coast tip.
The Ringing Leaf is the leaf of a dune growing grass that holds dunes together but in the wind also rings like a set of bells. It is very melodic and calming for those in the area. In some cases it is used to counteract the effects of Sirens.

Toxic Use: when put onto a weapon the mixture makes the individual sensitive to sound - so much so that it acts like an Audible Glamor spell on the recipient even though no one else can hear anything. (Small amounts used by a Rogue can increase Listening skill by +10% with only a 15% chance of overdose causing the above effects and possible hearing damage - save versus poison at +3)
