Potion of Cold Shielding

Rare Potion

Liquid Shield. The bright blue liquid in this bottle feels cold to the touch. It smells vaguely of pines and mint but oddly enough tastes more like a mug of hot chocolate.
When you drink this potion, you gain resistance to Cold damage. A flurry of snowflakes surround your body, whenever a creature within 5ft. of you hits you with a melee attack, the shield erupts with flames, dealing 2d8 Cold damage to the attacker. These effects last for 10 minutes.
