How can I use stone floors to prevent enemies from digging under my fort?

In Valheim, one of the most effective ways to prevent enemies from digging under your fort is by using stone floors as a defensive layer. Stone floors are a mid-to-late-game building material that can be crafted once you unlock the Stonecutter, which requires Iron and a Forge. Stone floors are impervious to most enemy attacks, including digging, making them an excellent choice for fortifying your base.\n\nTo begin, you must first gather the necessary resources to craft a Stonecutter. This requires 10 Wood and 2 Iron, which can be obtained by mining Muddy Scrap Piles in the Swamp biome. Once you have the Stonecutter, place it near your base to unlock stone building options. Stone floors require 6 Stone each, which can be mined from large boulders or gathered from the ground in the Meadows, Black Forest, or Mountains biomes.\n\nTo use stone floors effectively, you need to create a solid foundation around your fort. Start by clearing the ground around your base to ensure a flat surface. Then, lay down a layer of stone floors extending at least 2-3 meters outward from your walls. This creates a barrier that prevents enemies like Greydwarfs, Trolls, and even Fulings from digging under your defenses. The stone layer should be placed directly on the ground, as raising the terrain with the Hoe can sometimes leave gaps that enemies can exploit.\n\nOne common challenge is ensuring the stone floors are seamless and cover all vulnerable areas. Enemies can still target weak points, so it’s crucial to inspect your fort’s perimeter for any gaps. Use the Hammer tool to repair or replace damaged sections and ensure the stone layer is continuous. Additionally, consider reinforcing your walls with stone as well, as wooden walls are more susceptible to destruction.\n\nFor added protection, you can combine stone floors with other defensive measures. For example, dig a trench around your fort and line it with stone floors to create a moat. This not only prevents digging but also slows down enemy movement. Alternatively, you can build raised earth walls using the Hoe and then cover them with stone floors for a layered defense. This approach is particularly effective in the Plains biome, where Fulings and Lox pose significant threats.\n\nFinally, remember that stone floors are heavy and require strong support structures. Use stone pillars or core wood beams to reinforce your base and prevent collapse. This is especially important for multi-story forts or structures built on uneven terrain. By combining stone floors with strategic planning, you can create a nearly impenetrable fort that withstands even the toughest enemy assaults.\n\nIn summary, stone floors are a powerful tool for defending your Valheim fort. By crafting a Stonecutter, gathering stone, and laying down a solid foundation, you can prevent enemies from digging under your base. Combine this with trenches, raised walls, and strong support structures for maximum protection. With these strategies, you’ll be well-prepared to face any threat in the world of Valheim.
