What’s the optimal height for walls to prevent enemies from climbing over?

In Valheim, building defensible fortifications is crucial for surviving raids and protecting your base from hostile creatures. The optimal height for walls to prevent enemies from climbing over is 4 meters. This height ensures that most enemies, including Greydwarfs and Trolls, cannot scale your defenses. Walls shorter than 4 meters can be easily breached, especially during events like the Troll Raid or Fuling attacks in the Plains biome.\n\nTo achieve this height, you need to use the core building mechanics of Valheim. Start by crafting a Workbench, which is essential for constructing walls. Gather wood from nearby trees using an axe, and ensure you have enough materials to build a perimeter. Use the Hammer tool to access the building menu and select the Wood Wall or Stone Wall pieces. Stack two 2-meter wall pieces vertically to reach the 4-meter height. This design is effective in Meadows, Black Forest, and even Mountain biomes.\n\nOne common challenge is ensuring structural stability when building tall walls. Walls taller than 4 meters may require additional support beams or stone pillars to prevent collapse. Use Core Wood beams or Stone blocks to reinforce your walls, especially if you''re building in uneven terrain. For example, in the Swamp biome, where the ground is often uneven, combining stone foundations with wooden walls can create a sturdy barrier against Draugr and Blobs.\n\nAnother consideration is the type of enemies you''re defending against. In the Plains biome, Fulings and Lox can pose a significant threat. While 4-meter walls are sufficient for most enemies, adding spikes or trenches around your base can provide an extra layer of defense. Digging a trench 2-3 meters deep around your walls prevents enemies from reaching the base of your fortifications, making it harder for them to attack.\n\nFor advanced players, combining walls with defensive structures like watchtowers or archer platforms can enhance your base''s security. Use the Hoe tool to level the ground around your base, ensuring a flat surface for building. This is particularly useful in the Mountain biome, where uneven terrain can complicate construction. Additionally, consider using Iron Gates or reinforced doors to secure entry points, as these are harder for enemies to break through.\n\nFinally, always test your defenses by triggering raids or luring enemies to your base. This allows you to identify weak points and make adjustments. For example, if Trolls are able to damage your walls, consider upgrading to Stone Walls or adding a second layer of defenses. By following these steps and adapting your strategy to the biome and enemy types, you can create a secure and impenetrable fort in Valheim.\n\nPractical tips: Always keep a stockpile of building materials like wood, stone, and iron for quick repairs. Use the Hoe to level terrain before building walls, as uneven ground can create gaps in your defenses. Finally, consider building a moat or trench around your base for added protection, especially in high-threat biomes like the Plains or Mountains.
