Alchemy [Alkahest] - Master
Time: PT15H
Value: 500 gp

Tools: alchemist's supplies
Ability Check: DC 25 Intelligence check
Properties: fluid
Description: As an action, you can throw this flask up to 20 feet, shattering it on impact. Make a ranged attack against a creature, treating the medusa's essence as an improvised weapon. On a hit, the target must make a DC 20 Constitution saving throw. If the saving throw fails by 5 or more, the creature is instantly petrified. Otherwise, a creature that fails the save begins to turn to stone and is restrained. The restrained creature must repeat the saving throw at the end of its next turn, becoming petrified on a failure or ending the effect on a success. The petrification lasts until the creature is freed by greater restoration or similar magic.
