How does rain affect the durability of wooden structures?

Rain in Valheim has a significant impact on the durability of wooden structures, making it a key gameplay mechanic to manage for both new and experienced players. When it rains, wooden structures such as walls, floors, and roofs will gradually lose durability over time. This degradation occurs because rain causes wood to become wet, reducing its structural integrity. If left unchecked, wooden structures can eventually break, leaving your base vulnerable to damage or collapse.\n\nTo understand the mechanics, rain affects all exposed wooden structures, meaning any part of your build that is not covered by a roof or protected by other means will take damage. The rate of durability loss is consistent, but the damage is not immediate, giving players time to address the issue. For example, a wooden wall exposed to rain will lose 1 durability point every 10 seconds. While this may seem slow, prolonged rainstorms can lead to significant damage over time.\n\nOne of the most effective ways to protect wooden structures from rain is by using roofs. Roofs act as a shield, preventing rain from directly hitting the wood beneath them. To craft roofs, you will need to unlock the Hammer tool and the Building menu. Roofs are crafted using wood and require a Workbench nearby. Ensure that your roofs overlap sufficiently to cover all exposed wooden parts, as even small gaps can allow rain to seep through and cause damage.\n\nAnother solution is to upgrade your wooden structures to higher-tier materials, such as core wood or stone. Core wood, obtained from pine trees in the Black Forest biome, is more durable than regular wood and can withstand rain better. Stone structures, unlocked after defeating the first boss, Eikthyr, and obtaining the Antler Pickaxe, are completely immune to rain damage. However, stone requires more resources and advanced crafting stations, making it a mid-to-late-game option.\n\nFor early-game players, tar can be used to create weather-resistant wood. Tar is found in the Plains biome, typically near Fuling camps or in tar pits. Once collected, tar can be used at a Workbench to craft tarred wood, which is resistant to rain damage. This is a great option for players who want to maintain the aesthetic of wooden builds while improving durability.\n\nPractical examples include building a roofed porch to protect your Workbench or creating a covered walkway to shield your base''s exterior walls. If you notice rain damage on your structures, repair them using the Hammer tool and wood. Simply select the repair option and click on the damaged parts to restore them to full durability.\n\nIn summary, rain is a persistent threat to wooden structures in Valheim, but with proper planning and resource management, you can mitigate its effects. Use roofs to protect exposed wood, upgrade to more durable materials like core wood or stone, and consider tarred wood for weather resistance. Regularly inspect and repair your structures to ensure they remain intact during storms. By following these steps, you can maintain a sturdy and reliable base, no matter the weather.
