How do you find and exploit shipwrecks in the ocean biome?

Shipwrecks in Valheim''s ocean biome are valuable sources of rare resources, including chitin, which is essential for crafting the Abyssal Harpoon and Abyssal Razor. To find and exploit shipwrecks, you must first prepare adequately. Start by crafting a Karve or Longship, as these vessels are necessary for navigating the ocean biome. The Karve requires 30 Fine Wood, 10 Deer Hide, 20 Resin, and 80 Bronze Nails, while the Longship requires 40 Fine Wood, 10 Deer Hide, 100 Iron Nails, and 40 Ancient Bark. Both ships are built at the Workbench, but the Longship is more durable and faster, making it ideal for long ocean voyages.\n\nOnce your ship is ready, stock up on essential supplies. Bring a pickaxe, as it is required to harvest chitin from the barnacle-covered ribs of shipwrecks. Additionally, pack food, healing mead, and a weapon to defend against sea serpents, which are common in the ocean biome. A bow and arrows are particularly useful for ranged combat. It''s also wise to bring a portal and portal materials (20 Fine Wood and 2 Surtling Cores) to establish a quick return point if you die or need to resupply.\n\nTo locate shipwrecks, sail into the ocean biome and keep an eye out for large, broken wooden structures partially submerged in the water. These are the shipwrecks. They are often surrounded by barnacles, which appear as dark, spiky growths on the ribs of the wreck. Approach the wreck carefully, as sea serpents may be nearby. Dismount your ship and swim to the wreck, then use your pickaxe to mine the barnacles. Each barnacle yields 1-2 chitin, and a single shipwreck can provide 10-20 chitin, depending on its size.\n\nOne common challenge is dealing with sea serpents while harvesting chitin. If a serpent attacks, prioritize your safety. Use your bow to shoot it from a distance, or if you''re on your ship, sail away quickly. Serpents are dangerous but can be outrun, especially in a Longship. If you''re caught off guard, use healing mead to recover health and continue fighting or fleeing. Always keep your ship repaired and avoid lingering in one spot for too long, as serpents are more likely to spawn in open water.\n\nAnother tip is to explore the ocean biome during the day. Visibility is better, and serpents are less aggressive compared to nighttime. If you must explore at night, bring a Dverger Circlet or a torch to improve visibility. Additionally, mark shipwreck locations on your map for future visits, as chitin is a renewable resource, and barnacles will respawn over time.\n\nFinally, consider building a small outpost near the ocean biome to store resources and resupply. This can save time and reduce the risk of losing valuable items if you die. With proper preparation and strategy, shipwrecks can become a reliable source of chitin and other rare materials, making ocean exploration a rewarding part of your Valheim adventure.
