What is the best way to gather eitr for advanced forge upgrades?

Gathering Eitr in Valheim is essential for advanced forge upgrades, particularly for crafting high-tier gear and tools. Eitr is a rare resource found in the Mistlands biome, which is one of the most challenging areas in the game. To efficiently gather Eitr, you need to prepare thoroughly, understand the biome''s dangers, and use the right tools and strategies.\n\nFirst, you must unlock the Mistlands biome by progressing through the game. This biome is filled with dense fog, hostile creatures like Seekers and Gjalls, and unique resources such as Soft Tissue and Sap. Eitr is primarily obtained by refining Soft Tissue in a Sap Extractor, which requires a Black Forge. To build a Black Forge, you need Black Marble, Yggdrasil Wood, and Black Cores, all of which are found in the Mistlands. This means you must first establish a foothold in the biome to gather these materials.\n\nTo gather Soft Tissue, you need to defeat Dvergr enemies or loot Dvergr structures. Dvergr are neutral NPCs unless provoked, so approach carefully. Soft Tissue can also be found in Dvergr crates or by mining Petrified Bones scattered throughout the Mistlands. Once you have Soft Tissue, you need Sap to refine it into Eitr. Sap is obtained by placing Sap Extractors on Yggdrasil Roots, which are large, glowing tree-like structures in the Mistlands. Each Sap Extractor requires 10 Black Marble and 5 Black Cores to craft, so prioritize gathering these materials.\n\nOne of the biggest challenges in the Mistlands is navigating the dense fog and dealing with powerful enemies. To mitigate this, bring a Wisp Light, crafted from Yggdrasil Wood and Wisps, to clear the fog around you. Equip high-tier armor like Carapace or Padded Armor, and bring powerful weapons such as the Mistwalker or Arbalest. Always carry healing meads, stamina meads, and poison resistance potions to handle the biome''s threats.\n\nOnce you have a steady supply of Soft Tissue and Sap, return to your base and refine them into Eitr at the Black Forge. Each Soft Tissue yields 1 Eitr when combined with Sap. Eitr is used to craft advanced forge upgrades like the Eitr Refinery and Eitr-infused weapons and armor. These upgrades are crucial for tackling endgame content, so prioritize gathering Eitr as soon as you unlock the Mistlands biome.\n\nFor new players, focus on building a strong base and upgrading your gear before venturing into the Mistlands. Experienced Vikings should explore the biome in small groups to handle the increased difficulty. Always mark resource locations on your map and establish a safe outpost in the Mistlands to streamline resource gathering. With careful preparation and strategy, you can efficiently gather Eitr and unlock the full potential of your forge upgrades.
