How do I deal with troll raids in a shared base?

Troll raids in Valheim can be a significant threat to a shared base, especially if players are unprepared. These raids are triggered by the game''s event system, which spawns enemies near your base when certain conditions are met. Troll raids specifically occur after defeating the first boss, Eikthyr, and are marked by the message "The ground is shaking." Trolls are large, powerful enemies that deal massive damage to structures and players alike, making them a serious challenge for shared bases.\n\nTo defend against troll raids, the first step is to fortify your base. Build a sturdy perimeter wall using stone or reinforced wood, as these materials can withstand more damage than basic wood. Stone walls are particularly effective, but they require a Stonecutter, which is unlocked after defeating the first boss and acquiring bronze. If stone is not yet available, use core wood or reinforced wood for better durability. Ensure your walls are at least two layers thick to absorb more damage.\n\nNext, create defensive structures such as stake walls, trenches, or moats around your base. Trenches and moats are especially effective because trolls cannot cross them, forcing them to path around to your gates or other entry points. Digging a trench requires a pickaxe, which is crafted using wood and hard antler from Eikthyr. Make the trench at least two meters deep and three meters wide to prevent trolls from jumping over it. Place stake walls or spikes at the bottom of the trench for added protection.\n\nIn addition to physical defenses, prepare your team with the right weapons and tactics. Trolls are weak to piercing damage, so equip bows and arrows or spears. Finewood bows and flint arrows are effective early-game options, while later upgrades like the Huntsman bow and fire arrows can deal even more damage. Assign roles to your team members, such as archers to attack from a distance and melee fighters to distract trolls if they breach your defenses. Communication is key in a shared base, so use in-game chat or voice communication to coordinate your efforts.\n\nIf trolls do breach your defenses, focus on kiting them away from your base. Trolls are slow but deal massive damage with their attacks, so avoid engaging them in close combat unless necessary. Use the terrain to your advantage by leading them into narrow spaces or over traps. If your base is near a Black Forest biome, consider luring trolls into the forest, where they may aggro other enemies like Greydwarves, giving you time to regroup.\n\nFinally, always have a backup plan. Store valuable resources and crafting materials in secure chests or separate buildings away from your main base. If your base is destroyed, having a secondary location with essential supplies will allow you to rebuild quickly. Additionally, consider building a portal network to evacuate quickly if the situation becomes dire.\n\nIn summary, defending against troll raids in a shared base requires a combination of strong defenses, strategic planning, and teamwork. Fortify your base with sturdy walls and trenches, equip your team with the right weapons, and always have a backup plan. By following these steps, you can protect your shared base and continue thriving in Valheim.
