How can I use the Swamp biome’s crypts to prepare for Bonemass?

The Swamp biome’s crypts are a critical resource for preparing to face Bonemass, the third boss in Valheim. These crypts are filled with valuable materials, including Scrap Iron, Withered Bones, and other resources that will help you craft stronger gear and consumables. To begin, you’ll need to locate a Swamp biome, which is typically found near Black Forest or Meadows biomes. Once inside the Swamp, look for crypts—large, stone structures with green torches outside. These are your primary targets for preparation.\n\nBefore entering a crypt, ensure you are well-equipped. Bring a Bronze or Iron Mace, as the enemies inside, such as Draugr and Blobs, are weak to blunt damage. A shield is also essential for blocking attacks. Additionally, carry a Pickaxe to mine Muddy Scrap Piles, which yield Scrap Iron. Stock up on Poison Resistance Mead, as the Swamp is filled with poison hazards, including Blobs and the environment itself. This mead is crafted at a Fermenter using Honey, Thistle, Neck Tail, and Coal.\n\nInside the crypts, you’ll encounter tight corridors and enemies that can overwhelm you if you’re not careful. Use your shield to block incoming attacks and counter with your mace. Focus on mining Muddy Scrap Piles to gather Scrap Iron, which is essential for crafting Iron gear. You’ll also find Withered Bones, which are required to summon Bonemass. Collect as many as possible, as you’ll need 10 to summon the boss. Be mindful of your stamina, as mining and combat can drain it quickly. Bring plenty of food, such as Cooked Meat, Carrot Soup, or Sausages, to maintain your health and stamina.\n\nOnce you’ve gathered enough Scrap Iron, return to your base and smelt it into Iron at a Smelter. Use the Iron to craft Iron Armor, an Iron Mace, and an Iron Shield. These items will significantly increase your survivability and damage output during the Bonemass fight. Additionally, craft Frost Resistance Mead if you plan to explore the Mountains biome later, as Iron is also used to craft the Wolf Armor set.\n\nAnother key preparation step is to craft a Stagbreaker, a two-handed hammer that deals AoE (area of effect) damage. This weapon is particularly effective against Bonemass’s minions, which can swarm you during the fight. Stagbreaker is crafted using Core Wood, Deer Trophies, and Leather Scraps. Pair this with your Iron gear, and you’ll be well-prepared for the battle.\n\nFinally, consider building a small outpost near the Swamp biome to store your resources and respawn if needed. This will save you time and effort when traveling back and forth. Place a Portal at your base and another near the Swamp for quick access. With your Iron gear, Poison Resistance Mead, and Withered Bones in hand, you’re ready to summon and defeat Bonemass. Good luck, Viking!
