Can I use portals to escape the effects of the Bonemass boss fight?

In Valheim, portals are a powerful tool for fast travel, but they cannot be used to escape the effects of the Bonemass boss fight. Bonemass, the third boss in the game, is located in the Swamp biome and has a unique mechanic that prevents players from using portals during the fight. When you summon Bonemass, a large area around the boss altar becomes a restricted zone, disabling all portals within that radius. This means you cannot teleport away to avoid damage or replenish supplies mid-fight.\n\nTo prepare for the Bonemass fight, you must rely on traditional survival strategies rather than portal usage. First, ensure you have the best gear available. Iron armor and weapons are highly recommended, as they provide strong defense and damage output. Crafting a mace is particularly effective, as Bonemass is weak to blunt damage. Additionally, stock up on healing meads, stamina meads, and poison resistance meads, as Bonemass deals heavy poison damage and can quickly overwhelm unprepared players.\n\nBefore engaging Bonemass, set up a small base nearby with a bed, workbench, and storage chests. This base should be outside the restricted zone to allow respawning if you die. Place a portal at this base and link it to your main base for easy access to resources. However, remember that once the fight begins, you cannot use this portal until Bonemass is defeated. This setup ensures you can quickly return to the fight if needed.\n\nDuring the fight, focus on managing your stamina and health. Bonemass has three primary attacks: a melee swipe, a poison cloud, and a summoning ability that spawns adds. Use the terrain to your advantage by staying on higher ground or behind obstacles to avoid his melee attacks. Kite the adds away from Bonemass and deal with them quickly to avoid being overwhelmed. Poison resistance meads are essential for surviving his poison clouds, which can deal massive damage over time.\n\nIf you find yourself struggling, consider bringing a friend or two. Bonemass is significantly easier to defeat with a group, as you can divide his attention and share the workload of dealing with adds. Coordinate your attacks and healing to maximize efficiency. Alternatively, if you are playing solo, practice your dodging and timing to minimize damage taken.\n\nAfter defeating Bonemass, the restricted zone will lift, and you can use your portal again. Bonemass drops a trophy and a wishbone, which are essential for progressing in the game. The wishbone allows you to locate hidden silver veins in the Mountains biome, unlocking the next tier of gear and resources.\n\nIn summary, portals cannot be used to escape the Bonemass fight due to the restricted zone mechanic. Proper preparation, including crafting the right gear, stocking up on meads, and setting up a nearby base, is crucial for success. Focus on stamina management, poison resistance, and strategic positioning during the fight. With these tips, you can overcome Bonemass and continue your journey through Valheim.
