Gold Hound Vapor

Placing the opening near your mouth and inhaling this glittering, milky substance enhances your sense of smell for 1d4 days. However, the only thing you can smell with
any accuracy is gold. If you are within 50
feet of gold the size of a single coin or larger,
as a bonus action, you can pinpoint its location via smell as long as your sense of
smell is not otherwise hindered.
