Warmth Potion

Warmth Potion is a buff potion which buffs the player with Warmth. The buff increases defense against cold-themed enemies such as Snow Flinx. This lasts for 15 minutes, but can be cancelled at any time by right-clicking the icon. It is very useful during Frost Moon since the enemies found there use almost exclusively ice-based attacks. The damage reduction is about 40%.

Enemies this potion wards against seems to be all types that can inflict Chilled.
