How do you unlock the Charcoal Kiln for producing coal?

Unlocking the Charcoal Kiln in Valheim is a crucial step for progressing in the game, as it allows you to produce coal, a vital resource for smelting metals and crafting advanced items. To unlock the Charcoal Kiln, you must first defeat the first boss, Eikthyr, in the Meadows biome. Eikthyr is a stag-like creature that drops Hard Antlers, a key item required for crafting the Antler Pickaxe. This pickaxe is essential for mining Tin and Copper in the Black Forest biome, which are necessary for crafting the Kiln.\n\nOnce you have defeated Eikthyr and crafted the Antler Pickaxe, head to the Black Forest biome. This biome is identifiable by its dense pine trees, rocky terrain, and occasional Greydwarf enemies. In the Black Forest, you will find Copper deposits (large, greenish rocks) and Tin deposits (small, shiny rocks near water). Use your Antler Pickaxe to mine these resources. Copper requires a significant amount of mining, so be prepared to spend some time gathering enough ore.\n\nAfter collecting Copper and Tin, return to your base and smelt the ores in a Smelter. To build a Smelter, you will need 20 Stone and 5 Surtling Cores. Surtling Cores can be found in Burial Chambers in the Black Forest or dropped by Surtlings in the Ashlands biome. Once you have smelted Copper and Tin, combine them at a Forge to create Bronze, which is used to craft the Charcoal Kiln.\n\nTo craft the Charcoal Kiln, you will need 20 Stone and 5 Surtling Cores. Place the Kiln near your Smelter for efficient resource management. The Kiln converts Wood into Coal, which is used to fuel the Smelter and Forge. Simply load the Kiln with Wood, and it will produce Coal over time. Each piece of Wood yields one Coal, so gather plenty of Wood to keep your production running smoothly.\n\nA common challenge players face is running out of Wood or Surtling Cores. To address this, always carry a Bronze Axe to chop down trees efficiently, and explore multiple Burial Chambers in the Black Forest to gather Surtling Cores. Additionally, consider building a portal near your mining site to reduce travel time and increase resource gathering efficiency.\n\nIn summary, unlocking the Charcoal Kiln involves defeating Eikthyr, crafting the Antler Pickaxe, mining Copper and Tin in the Black Forest, smelting ores, and gathering Surtling Cores. Once built, the Kiln is a game-changer for producing Coal, enabling you to smelt metals and craft advanced tools and weapons. Always plan ahead, gather resources in bulk, and optimize your base layout to streamline your production process.
