This very unusual Concoction turns the imbiber translucent, as though made of glass. It can only be made as an Elixir. When it takes effect, the imbiber gains favour on all Stealth checks. Unfortunately, it is unpredictable. It will last a guaranteed two minutes. At the end of each further minute that it is in effect, roll a d8. If the die comes up showing a one, the effects of the Elixir end.
