How do you unlock the Wisp Fountain, and what does it do?

The Wisp Fountain is a unique structure in Valheim that allows players to collect Wisps, a valuable resource used for crafting and exploration in the Mistlands biome. To unlock the Wisp Fountain, you must first defeat Yagluth, the fifth boss in Valheim, located in the Plains biome. Yagluth drops a Yagluth Thing, which is required to craft the Wisp Fountain at the Artisan Table.\n\nTo craft the Wisp Fountain, you will need the following materials: 1 Yagluth Thing, 15 Black Marble, and 10 Wisps. Black Marble is obtained by mining Petrified Bones in the Mistlands biome, while Wisps are collected using the Wisp Torch or Wisp Light, which are crafted after unlocking the Mistlands biome. The Artisan Table is unlocked after defeating Moder, the fourth boss, and requires a Forge to craft.\n\nOnce the Wisp Fountain is built, it generates Wisps over time, which can be collected by interacting with the fountain. Wisps are essential for crafting Wisp Torches and Wisp Lights, which help players navigate the dense mist in the Mistlands biome. Without Wisps, visibility in the Mistlands is severely limited, making exploration and combat much more challenging.\n\nTo maximize the efficiency of your Wisp Fountain, place it in a secure location within your base, preferably near other crafting stations. This ensures easy access to Wisps when needed. Additionally, consider building multiple Wisp Fountains if you plan to explore the Mistlands extensively, as Wisps are consumed quickly when crafting Wisp Lights and Torches.\n\nA common challenge players face is locating Petrified Bones in the Mistlands biome. These resources are often found near Dvergr structures or scattered across the biome. Use a Wishbone, obtained from defeating Bonemass, to detect Petrified Bones underground. This tool significantly speeds up the gathering process.\n\nIn summary, the Wisp Fountain is a crucial structure for late-game progression in Valheim, particularly for navigating the Mistlands biome. By defeating Yagluth, gathering Black Marble, and crafting the fountain, you can ensure a steady supply of Wisps for your adventures. Plan your resource gathering carefully and protect your Wisp Fountain to maintain a reliable source of this vital resource.
