Valheim Bonemass boss guide - how to defeat the third boss

Bonemass is one of the hardest fights in the entire game, forcing players to come prepared before taking on the green behemoth. Before attempting to fight this Valheim boss, you need to become familiar with the Swamp biome. The poisonous area features a number of powerful enemies that creep around the surrounding area such as skeletons, draugrs, and infuriating blobs, ready to drain your health in an instant. As for your Valheim armour, while skilled players could get away with a set of troll armour during this boss battle, you may want to invest in iron armour if you find this fight difficult. Iron armour features resistance to physical attacks, perfect against Bonemass' primary attack. Before you attempt to fight Bonemass, you'll need to find his location. The Swamps contain dungeons known as Sunken Crypts. You have the chance to find a runestone in one of these crypts - it may take you several attempts as the runestone is quite rare. Fortunately, these locations always contain muddy scrap piles which drop iron scraps, the material needed to craft Valheim iron. Here's everything you need to know about how to summon and defeat Bonemass in Valheim.
