How do I upgrade the Warm Doublet in The Legend of Zelda: Breath of the Wild?

The Warm Doublet is a unique piece of armor in The Legend of Zelda: Breath of the Wild that provides cold resistance, making it essential for exploring colder regions like the Great Plateau or Hebra Mountains. However, unlike most armor sets in the game, the Warm Doublet cannot be upgraded at Great Fairy Fountains. This is a common point of confusion for players, as most armor pieces can be enhanced to increase their defense or unlock set bonuses. Since the Warm Doublet cannot be upgraded, its primary purpose is to provide early-game cold resistance, and players will eventually need to replace it with more advanced cold-resistant gear as they progress.

To obtain the Warm Doublet, players must complete a specific quest on the Great Plateau. Early in the game, after leaving the Shrine of Resurrection, players will encounter the Old Man near the Temple of Time. He will give Link a quest to cook a dish using Spicy Peppers, which can be found near the Old Man's cabin. By cooking a dish with Spicy Peppers, such as a Spicy Pepper Steak or Spicy Sauteed Peppers, and presenting it to the Old Man, he will reward Link with the Warm Doublet. Alternatively, players can find the Warm Doublet in a chest inside the Old Man's cabin if they climb to the top of Mount Hylia and speak to him there. This is a straightforward process, but it is important to note that the Warm Doublet is a one-time reward and cannot be obtained again if lost or sold.

Since the Warm Doublet cannot be upgraded, players should consider alternative cold-resistant gear as they progress through the game. One of the best options is the Snowquill Set, which can be purchased in Rito Village. This set includes the Snowquill Headdress, Snowquill Tunic, and Snowquill Trousers, all of which provide cold resistance. The Snowquill Set can be upgraded at Great Fairy Fountains, making it a more durable and effective choice for cold environments. To upgrade the Snowquill Set, players will need materials such as Warm Darner, Summerwing Butterfly, and Fireproof Lizard, which can be found in various regions of Hyrule. Upgrading the Snowquill Set to level two will also unlock the set bonus, Unfreezable, which prevents Link from being frozen by enemies like Ice Wizzrobes or Frost Taluses.

Another alternative is the Rito Set, which is specifically designed for cold resistance and can be obtained by completing the Divine Beast Vah Medoh quest. This set includes the Rito Headpiece, Rito Tunic, and Rito Trousers, and it can also be upgraded at Great Fairy Fountains. The Rito Set is particularly useful for players who prefer a more lightweight and agile playstyle, as it provides both cold resistance and enhanced mobility in cold environments.

For players who prefer a more versatile approach, combining different pieces of cold-resistant gear can be an effective strategy. For example, wearing the Warm Doublet with other cold-resistant items like the Snow Boots or the Hylian Hood can provide sufficient protection while allowing for greater customization. Additionally, consuming cold-resistant elixirs or dishes can temporarily boost Link's resistance to cold, making it easier to explore frigid areas without relying solely on armor.

In summary, while the Warm Doublet is a useful early-game item for cold resistance, it cannot be upgraded. Players should focus on obtaining and upgrading more advanced cold-resistant gear like the Snowquill Set or Rito Set as they progress through the game. By combining different pieces of gear and using consumables, players can effectively manage their cold resistance and explore even the most extreme environments in Hyrule.
