As two actions, you can create a vial of liquid that shifts from orange to blue and from hot to cold. A creature can drink the contents as an action so their body automatically adapts to hostile environments. The creature can adapt to underwater, extremely hot, extremely cold, or airless environments, allowing it to survive as if it were a creature native to that environment. The creature can breathe and move (though penalties to movement and attacks, if any for a particular environment, remain), and it takes no damage simply from being in that environment. You need not specify what environment the potion is adapting to when you create this concoction; simply activate it, and the creature’s body will instantly adapt to any hostile environment as needed throughout the duration.
The creature can somewhat adapt to extreme environmental features such as acid, lava, fire, and electricity. Any environmental feature that normally directly deals 1 or more dice of damage each round deals the creature only half the usual amount of damage.
