This fine powder appears much like any other dust unless a careful examination is conducted. The latter will reveal it to be more like a metal dust, but very fine and very light. 

One handful of this substance flung into the air will coat all objects, making them visible even if they are invisible, out of phase, astral, or ethereal. 

Note that the dust will also reveal mirror images and projected images for what they are, and it likewise negates the effects of cloaks of displacement or elvenkind or robes of blending. 

Appearance lasts for 2-20 turns. 

It is typically in small silk packets or hollow bone blow tubes. A packet can be shaken out to cover an area with a radius of 10-ft from the user. A tube can be blown in a cone shape, 1-ft wide at the start, 15-ft at the end, and 20-ft long. From 5 to 50 containers can be in one place.
