Something's Rotten in Faerun
Dust of Appearance
This fine powder appears like any other dust unless a careful examination is conducted. This will reveal it to be a very fine, very light, metallic dust. A single 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 and robes of blending. The dust’s effect lasts for 2d10 turns.
This dust of appearance is stored in small silk packets. A packet can be shaken out to cover an area with a radius of 10 feet from the user.
