What’s the best way to reinforce walls against enemy attacks?

Reinforcing walls in Valheim is essential to protect your base from enemy attacks, especially as you progress into harder biomes like the Plains or face raids from Fulings or Trolls. The game uses a structural integrity system, meaning walls and other structures can collapse if not properly supported. To reinforce walls, you need to focus on both durability and structural stability. Start by upgrading your walls to higher-tier materials like stone or iron, which offer significantly more health than basic wood.\n\nTo upgrade walls, you’ll need a workbench nearby and the appropriate materials. For example, stone walls require stone and a stonecutter, which is crafted using 10 wood and 2 iron. Iron-reinforced wood walls, on the other hand, require iron nails and core wood. These materials are found in specific biomes: stone is abundant in the Black Forest and Mountains, while iron is obtained from muddy scrap piles in the Swamp biome. Always ensure you have a steady supply of these resources before starting your upgrades.\n\nAnother key aspect of reinforcing walls is ensuring proper structural support. Walls that are too tall or lack adequate support beams will collapse. Use core wood beams or iron beams to reinforce the structure. Core wood beams are crafted from core wood, found in the Black Forest by chopping down pine trees. Iron beams require iron and are crafted at a forge. Place these beams vertically or horizontally along your walls to distribute the load and prevent collapse.\n\nDefensive structures like stake walls or raised earth walls can also provide additional protection. Stake walls are crafted using wood and can be placed around your base perimeter to slow down enemies. Raised earth walls, created using the hoe and stone, are particularly effective against Trolls and other large enemies, as they cannot be destroyed. Combine these with reinforced walls for a layered defense system.\n\nFinally, consider the layout of your base. Avoid placing walls too close to trees or rocks, as enemies can use these to climb over. Create a moat or trench around your base using the pickaxe to dig, which forces enemies to take a longer path and gives you more time to defend. Always keep your workbench, forge, and other crafting stations protected within your reinforced walls to ensure you can repair and upgrade during raids.\n\nPractical tips: Always carry a hammer and repair materials during raids to fix damaged walls quickly. Use bonfires or torches to light up your base, as some enemies avoid fire. For advanced players, consider using ballistae or other defensive traps to further enhance your base’s security. By combining upgraded materials, structural support, and strategic layout, you can create a base that withstands even the toughest enemy attacks.
