How do you find and use Windmills to aid sailing in Valheim?

Windmills in Valheim are not directly used for sailing but are essential for processing resources that can aid in ocean exploration. To find and use Windmills effectively, you must first progress through the game and unlock the necessary crafting recipes. Windmills are primarily used to grind barley and flax into flour and linen thread, which are critical for crafting high-tier food and armor, respectively. These resources are vital for surviving the harsh ocean biome and preparing for long voyages.\n\nTo craft a Windmill, you must first defeat Moder, the fourth boss in Valheim, located in the Mountain biome. Moder drops Dragon Tears, which are required to build the Artisan Table. The Artisan Table unlocks advanced crafting recipes, including the Windmill. To build a Windmill, you will need 20 Stone, 30 Wood, and 30 Iron Nails. Place the Windmill in an open area with consistent wind, as it requires wind to function. Windmills work best in elevated or flat areas, so avoid placing them near tall structures or trees.\n\nOnce your Windmill is operational, you can use it to process barley and flax. Barley is found in the Plains biome, a dangerous area filled with Fulings and Deathsquitos. To safely farm barley, establish a small outpost with defensive walls and a portal for quick escapes. Flax is also found in the Plains biome, often near Fuling villages. Both crops require a Cultivator to plant, which is crafted using Bronze and Core Wood. Plant barley and flax in the Plains biome, as they will not grow in other biomes.\n\nAfter harvesting barley and flax, place them in the Windmill to produce flour and linen thread. Flour is used to craft bread, lox meat pie, and fish wraps, which provide high stamina and health regeneration—essential for long ocean voyages. Linen thread is used to craft padded armor and the Draugr Fang bow, both of which are critical for surviving the ocean biome and its threats, such as Serpents and sea storms.\n\nWhen preparing for ocean exploration, ensure your ship is equipped with the best possible gear. The Longship is the ideal vessel for ocean travel, as it has ample storage and durability. Stock your ship with high-tier food, such as bread and lox meat pie, to maintain stamina during long journeys. Bring a Draugr Fang bow and plenty of arrows to fend off Serpents, which are common in the ocean biome. Additionally, craft a Karve or Longship portal kit to establish a quick return point in case of emergencies.\n\nOne common challenge players face is managing inventory space during ocean exploration. To address this, build a small base on a nearby island or coastline to store excess resources. Use portals to transport valuable items back to your main base, reducing the risk of losing them to Serpents or storms. Another tip is to sail during the day, as visibility is better, and Serpents are less aggressive. Always keep an eye on the weather, as storms can damage your ship and make sailing more dangerous.\n\nIn summary, Windmills are a crucial part of preparing for ocean exploration in Valheim. By processing barley and flax into flour and linen thread, you can craft high-tier food and armor, which are essential for surviving the ocean biome. Defeat Moder to unlock the Windmill recipe, farm barley and flax in the Plains biome, and use the processed resources to prepare for long voyages. With proper preparation and strategic planning, you can conquer the ocean biome and uncover its many secrets.
