How can I use the Stonecutter to plan a stone fortress in the Plains biome?

The Stonecutter is an essential tool for building stone structures in Valheim, especially when planning a stone fortress in the challenging Plains biome. To use the Stonecutter effectively, you must first unlock it by defeating the second boss, The Elder, and obtaining the Swamp Key. This key grants access to Sunken Crypts in the Swamp biome, where you can mine Scrap Iron. Smelt the Scrap Iron into Iron Bars at a Smelter, and then craft the Stonecutter at a Workbench using 10 Wood and 2 Iron Bars.\n\nOnce the Stonecutter is placed near your building site, it unlocks stone-based building pieces, such as stone walls, floors, and arches. In the Plains biome, where Deathsquitos and Fulings pose constant threats, a stone fortress provides superior durability compared to wood. Start by gathering stone from nearby boulders or mining it in the Black Forest biome. You’ll need a lot of stone, so consider using a Cart or Portal to transport resources efficiently.\n\nBegin your fortress by laying a strong foundation. Use stone floors to create a flat base, ensuring the ground is level. Uneven terrain in the Plains can make building tricky, so use the Hoe to flatten the area. Next, build stone walls around the perimeter. Stone walls are resistant to most enemy attacks, making them ideal for defense. For added security, incorporate stone arches and pillars to create multiple layers of walls, which can slow down or funnel enemies into kill zones.\n\nOne common challenge in the Plains biome is the lack of natural cover. To mitigate this, build elevated platforms or towers within your fortress. These provide vantage points for archers to snipe Deathsquitos and Fulings from a safe distance. Use stone stairs or ladders to connect different levels of your fortress. Additionally, consider adding a moat or trench around your fortress to prevent enemies from reaching your walls. Digging with the Pickaxe is time-consuming but highly effective for creating defensive barriers.\n\nLighting is another critical aspect of fortress planning. Place Sconces or Standing Braziers along the walls and inside the fortress to keep it well-lit at night. This not only improves visibility but also deters Greydwarfs and other creatures that spawn in the dark. For a more advanced setup, use Bonfires or Hearth fires to provide warmth and light while adding a cozy aesthetic to your fortress.\n\nFinally, don’t forget to include functional spaces within your fortress. Build a Workshop area with a Forge, Workbench, and Stonecutter for crafting and repairs. Add storage chests for organizing resources and a Portal for quick travel to other biomes. If you plan to farm in the Plains, designate a secure area within the fortress for cultivating Barley and Flax, which are exclusive to this biome.\n\nIn summary, the Stonecutter is a game-changing tool for building a stone fortress in the Plains biome. By gathering ample stone, leveling the terrain, and incorporating defensive features like walls, moats, and towers, you can create a formidable stronghold. Use lighting and functional spaces to enhance both practicality and aesthetics. With careful planning and resource management, your stone fortress will stand as a testament to your Viking ingenuity.
