Earthen Kettle
Wondrous item, rare
This kettle is carved entirely of dark stone. It is 9 inches tall, 6 inches in diameter, weighs 2 pounds, and can hold up to 1.5 liters of liquid. The kettle comes with a stone lid and handle. If water is poured into the kettle and heated over a fire for 1 minute, it transforms into one of the following concoctions of your choice:
Stone Soup. This clear broth has miniscule stone flecks floating in it. A creature that drinks this liquid gains immunity to petrification and any spell or effect that would alter its form for 8 hours.
Clay Milk. This opaque liquid is the color of terracotta. A creature that drinks this liquid becomes moldable like putty for 8 hours. While putty-like, a creature has advantage on checks and saving throws to resist being grappled, and can squeeze through spaces as narrow as 2 inches wide as if they were difficult terrain.
Dusty Brew. This cloudy gray liquid swirls with black particles. A creature that drinks this liquid exudes a cloud of dust from their skin, lightly obscuring themself for 8 hours. As an action, a dusty creature can become heavily obscured until the end of their next turn. This heavy obscurement ends early if the creature moves or a strong wind dissipates the dust. A creature under the effect of this brew can see through their own dust as if normal.
Gem Wine. This translucent liquid shimmers with a panoply of vibrant colors. A creature that drinks this liquid can grant themself a +10 bonus to one attack roll, ability check, or saving throw within the next 8 hours. You may add this bonus after you see the roll, but before the GM says whether the roll succeeds or fails.
The kettle brews 6 servings of your chosen concoction. Once brewed, a concoction lasts 1 hour before it reverts to water and loses its magical properties. It takes an action to drink a concoction created by this kettle. Once the kettle has been used to brew a liquid, it cannot be used again for 1d4 days.
