How do you unlock the recipe for the Porcupine, and what materials are needed?

The Porcupine is one of the most powerful maces in Valheim, combining blunt and piercing damage, making it highly effective against a variety of enemies. To unlock the recipe for the Porcupine, you must first progress through the game and acquire specific materials from late-game biomes. The Porcupine is crafted at a level 4 Forge, so ensure your Forge is fully upgraded before attempting to craft it.\n\nTo unlock the recipe, you need to gather and hold specific materials in your inventory. These materials include Linen Thread, Fine Wood, Iron, and Needles. Linen Thread is crafted from Flax, which is found in the Plains biome. Fine Wood is obtained by chopping down Birch or Oak trees, while Iron is mined from Muddy Scrap Piles in the Swamp biome. Needles are dropped by Deathsquitos, also found in the Plains biome. Once you have these materials in your inventory, the Porcupine recipe will automatically unlock.\n\nTo craft the Porcupine, you will need the following materials: 5 Fine Wood, 20 Iron, 10 Linen Thread, and 5 Needles. Fine Wood is relatively easy to obtain, but Iron requires significant effort. You must first locate Sunken Crypts in the Swamp biome, which are guarded by Draugr and other enemies. Inside these crypts, you will find Muddy Scrap Piles that yield Iron when mined with a Bronze or Iron Pickaxe. Smelt the Iron in a Smelter to produce usable Iron bars.\n\nLinen Thread is crafted from Flax, which grows in Fuling Villages in the Plains biome. Flax can only be harvested after defeating the game''s fourth boss, Moder, as it requires a Black Metal Pickaxe or better to break. Once you have Flax, process it into Linen Thread at a Spinning Wheel. Needles are dropped by Deathsquitos, aggressive flying enemies in the Plains biome. These creatures are fast and deadly, so approach them with caution. Use a bow or shield to counter their attacks and collect Needles from their drops.\n\nOnce you have all the materials, head to a level 4 Forge to craft the Porcupine. Upgrading your Forge requires additional materials like Chains, Anvils, and Tool Shelves, so ensure you have these ready. The Porcupine is a versatile weapon, dealing both blunt and piercing damage, making it effective against enemies resistant to one type of damage. It is particularly useful in the Plains biome, where enemies like Fulings and Loxes are common.\n\nFor new players, the journey to crafting the Porcupine may seem daunting, but it is a rewarding endgame goal. Focus on progressing through the biomes in order: Meadows, Black Forest, Swamp, Mountains, and finally Plains. Each biome introduces new challenges and resources, so take your time to prepare. Experienced Vikings can speed up the process by prioritizing key materials and using efficient farming strategies.\n\nPractical tips for crafting the Porcupine include always carrying a shield when exploring the Plains biome to counter Deathsquitos. Use a Stagbreaker or Iron Sledge to clear Fuling Villages safely, as these weapons deal area-of-effect damage. When mining Iron in the Swamp, bring Poison Resistance Mead to mitigate damage from Blobs and Oozers. Finally, always upgrade your Forge and other crafting stations to maximize efficiency and unlock advanced recipes.\n\nThe Porcupine is a testament to your progress in Valheim, showcasing your ability to conquer the game''s toughest challenges. With its unique damage types and high durability, it is a weapon worth the effort for any Viking aiming to dominate the Plains and beyond.
