Elixir of Hiding

Potion, rare

This colorless, watery liquid grants an intuitive sense for the best ways to sneak and remain hidden. When you drink it, you have advantage on Dexterity (Stealth) checks.

In addition, if you are prone and do not move on your turn, you can use an action to become invisible as long as you remain prone and unmoving. If you attack or cast a spell while invisible, the effect ends.
