How do I build a fire indoors without causing smoke damage?

Building a fire indoors in Valheim is essential for survival, as it provides warmth, light, and the ability to cook food. However, if not done correctly, smoke buildup can damage your health and structures. To avoid this, you need to understand the game''s smoke mechanics and how to properly ventilate your indoor fires.\n\nSmoke in Valheim behaves realistically, rising upward and dispersing if it has an exit. If smoke accumulates indoors, it will cause damage to both the player and nearby structures. To prevent this, you must create a ventilation system. The simplest way is to leave an open space above the fire, such as a hole in the roof or a chimney. This allows smoke to escape naturally.\n\nTo build a fire indoors, start by crafting a Campfire or a Hearth. A Campfire requires 5 Stone and 2 Wood, while a Hearth requires 15 Stone and is larger and more durable. Place the fire in a central location within your structure, ensuring there is enough space above it for smoke to rise. If you''re using a Campfire, make sure it''s not too close to walls or other flammable objects, as it can spread fire.\n\nNext, create a chimney or ventilation hole. For a chimney, build a vertical stack of walls or beams above the fire, leaving the top open. You can use Wood or Stone materials for this. If you prefer a simpler solution, cut a hole in the roof directly above the fire. This works well in smaller structures or temporary shelters. Be mindful of rain, as an open hole can let water in and extinguish your fire.\n\nIn larger buildings, you can design a more elaborate ventilation system. For example, build a raised roof section with angled beams to direct smoke upward and out. This not only looks aesthetically pleasing but also ensures proper airflow. If you''re in a biome like the Mountains or Plains, where weather conditions are harsher, consider adding a roof over the chimney to prevent snow or rain from entering.\n\nAnother practical tip is to use the Hearth instead of the Campfire for larger indoor spaces. The Hearth produces less smoke relative to its size and is more efficient for cooking and heating. Additionally, it can be placed closer to walls without risking fire spread. However, it requires more resources to build, so plan accordingly.\n\nFor players in the early game, a simple Campfire with a roof hole is sufficient. As you progress and gather more resources, you can upgrade to a Hearth and design more sophisticated ventilation systems. Always test your setup by lighting the fire and observing the smoke flow. If smoke lingers, adjust the design by widening the chimney or raising the roof.\n\nFinally, remember that fires require fuel to burn. Keep a supply of Wood or Coal nearby to maintain your fire. If you''re exploring or building in colder biomes like the Mountains, having a reliable indoor fire is crucial for survival. By following these steps, you can enjoy the benefits of an indoor fire without the risks of smoke damage.\n\nIn summary, building a fire indoors in Valheim requires careful planning and attention to smoke mechanics. Use chimneys, roof holes, or raised roof sections to ventilate smoke effectively. Choose the right type of fire for your needs, whether it''s a simple Campfire or a more advanced Hearth. With these tips, you can create a safe and functional indoor fire to enhance your survival experience.
