Breath of the Wild
"This dragonfly has a special organ that causes it to sweat profusely. Cook it with monster parts for an elixir that will raise your core temperature so you can resist the cold."
Warm Darners can be cooked with monster parts to create an elixir that will provide cold resistance or sold to shop-vendors for 2 rupees.
A Warm Darner can be cooked alongside monster parts to create Elixirs. The Warm Darner will give Link Cold Resistance. When cooked with a monster part that has no specific enhancement, such as a Bokoblin Horn, Link will create a Spicy Elixir. This will temporarily allow Link to travel into colder climates without taking damage. If Link cooks a Warm Darner along with food, it will result in Link making Dubious Food.
As an alternative ingredient, Link can also cook a Summerwing Butterfly. The Summerwing Butterfly and Warm Darner have identical effects when cooking elixirs.
