How do you unlock the Wisp Fountain for light farming?

The Wisp Fountain is a late-game structure in Valheim that provides a renewable source of Wisps, essential for farming in the Mistlands biome. To unlock the Wisp Fountain, you must first progress through the game and gather specific resources. This guide will walk you through the steps, mechanics, and tips to successfully build and use the Wisp Fountain for light farming.\n\nFirst, you need to defeat Yagluth, the fifth boss in Valheim, located in the Plains biome. Yagluth drops the Yagluth Thing, which is required to craft the Wisp Fountain. After defeating Yagluth, you will gain access to the Mistlands biome, where you can find the necessary materials for the Wisp Fountain. The Mistlands is a dangerous biome filled with hostile creatures, so ensure you are well-equipped with upgraded gear and food buffs before venturing in.\n\nTo craft the Wisp Fountain, you will need the following materials: 1 Yagluth Thing, 10 Black Marble, and 5 Dvergr Extractor Fragments. Black Marble is obtained by mining Petrified Bones in the Mistlands, while Dvergr Extractor Fragments are dropped by Dvergr enemies or found in Dvergr structures. Once you have gathered these materials, you can craft the Wisp Fountain at the Artisan Table, which requires a level 5 Forge to build.\n\nThe Wisp Fountain generates Wisps over time, which are used to craft Wisp Torches and Wisp Lanterns. These light sources are crucial for farming in the Mistlands, as the biome is shrouded in thick mist that reduces visibility. Place the Wisp Fountain near your farming area to ensure a steady supply of Wisps. Each Wisp Fountain can hold up to 10 Wisps, so you may need multiple fountains depending on the size of your farm.\n\nOne common challenge is surviving in the Mistlands while gathering resources. To mitigate this, bring a portal with you to quickly escape dangerous situations. Additionally, use the Wisplight, a craftable item that clears the mist around you, to improve visibility and navigation. The Wisplight requires 1 Wisp and 1 Silver to craft, making it a valuable tool for exploring the Mistlands.\n\nFor efficient farming, place Wisp Torches or Wisp Lanterns around your crops to ensure they receive adequate light. This is especially important for crops like Barley and Flax, which require light to grow. The Wisp Fountain ensures you never run out of Wisps, allowing you to maintain a sustainable farming operation in the Mistlands.\n\nIn summary, unlocking the Wisp Fountain involves defeating Yagluth, gathering Black Marble and Dvergr Extractor Fragments, and crafting the structure at an Artisan Table. Use the Wisps it generates to create light sources for farming in the Mistlands. With proper preparation and resource management, the Wisp Fountain will become an invaluable asset for late-game farming in Valheim.
