Obsidian panpipes

Made from fifteen cylindrical obsidian pipes bound together by smooth gold bands, the set of gleaming obsidian panpipes is capable of producing a sound that lures out five rats to the city location wherein it is played, though it is ineffective when played in the sewers. Each pipe is differently shaped, with some waving and others corkscrewing. A plate of black glass is attached to the backside of the assembly, and a different gemstone is inlayed on the front of each pipe.

These panpipes was once on sale at Merentesh's Shop of Wonders in Delos, but it has since been discontinued.
