Potion of Frozen Concoction

Potion, rare

You can throw this potion at a point within 30 ft. All creatures within 5 ft. of where it lands must make a DC 15 Dexterity saving throw. A creature that fails the saving throw takes 2d8 cold damage and is slowed (as the spell) for 1 round. A creature that succeeds on the saving throw takes half this damage and is not slowed.
