Background
The harnessing of chaos energy has given tinkers a more level playing field when dealing with a world of arcane magic. This technology is new and dangerous, and isn’t seen in many devices, but it shows up in unlikely places.

The gnomish cloaking device doesn’t need to be a cloak, necessarily, but the tinker that created it had a flair for style. To all eyes it is a stylish, gray woolen cloak, but the chaos generator is hidden in a small box that is woven into the cloak at the base of the neck and connected by a thin wire to the brooch that clasps the cloak at the shoulder.

When the wearer pushes a button set into the brooch (often hidden) the chaos generator revs up and the molecules in the air around the wearer begin to vibrate at a rate that causes the user to appear to become invisible.
