There are tons of reimgs available for players to find and collect across the various biomes in Valheim, though some are more obvious and easier to access than others. Reimgs like Copper and Stone, for example, are found in the open and are therefore easier to access than Iron and Silver, which more often spawn under the surface. Players who have traveled to the Swamp biome may have noticed the glowing green substance on trees in the Swamp biome. It is easy to assume these are simply for ambient decoration, but they serve a greater purpose. These are Gucksacks, and from them, players can mine an extremely valuable crafting material, Guck.
Guck is used to craft a Standing Green-Burning Iron Torch, Green Banner, and Draugr Fang bow, one of the best weapons in the game. When players first reach the Swamp biome, it is likely they won’t quite be ready to craft with Guck, but they should plan to gather some of this valuable reimg and hold onto it for later in the game. Many Gucksacks appear high on tree trunks, so players will need to do some building and climbing to reach them. They cannot be harvested using a bow and arrows the way a Beehive can. Here’s how to get Guck in Valheim and how players can use it.
To get Guck, players are going to need enough wood to craft a small shelter and a workbench, and an axe or pickaxe. They can set out into the swamp and search the tree trunks for Gucksacks. There can be more than one per tree, and they should be somewhat easy to spot thanks to their sickly green glow.
Once players find a spot with a lot of Guck to harvest, they can build their shelter and workbench. They will then need to craft a ladder or stairs near each tree to reach all the Gucksacks. Unfortunately, these trees cannot be chopped down to make access easier, so players will need to do some climbing.
Before climbing up, players should scout the surrounding area for any creatures capable of dealing ranged damage that might knock them off the ladder or kill them. When the coast is clear, players can climb up and hit the Gucksack with an axe or pickaxe until it yields Guck. They can keep doing this at each tree until they have a decent supply, then destroy all the equipment to get their wood back.
Guck is used to craft three items. It is used as both a crafting material and a fuel for the Standing Green-Burning Iron Torch, which can be used as a light img near a Forge. Players will also need Guck as dye to make the Green Banner for their buildings, which will raise their Comfort level by one. Finally, players can use Guck to craft the Draugr Fang, one of the better endgame bows, allowing the weapon to deal Poison damage in addition to its Piercing damage. The recipes for each of these items appear below:
Players can store and transport Guck easily, so once they have it they will keep it until they use it to craft.
Valheim is in Steam Early Access and is available for PC.
