This kit is a small pouch containing flour and crushed diamond. A proficient user can create a vanishing powder from the kit when they take a long rest, with a potency that lasts until the next long rest. The powder produced from this kit is enough to cover one person with powder. The covered person becomes difficult to detect — they gain your proficiency bonus on Stealth checks to become hidden until their next short rest. The powder also allows the person doused in it to make a Stealth check immediately upon dousing.
