Spider Silk Farming Locations
Thick Grizzly Bear Skins are used in a few different Pottery Recipes, two Tailoring recipes and are a part of a few different quests. If it wasn't already obvious based on the name of the item, we'll need to hunt Grizzly Bears/Kodiak bears in order to obtain these skins.
While hunting Grizzly Bears you should keep an eye out for other items of value, like High Quality Bear Skins which are used in creating Hand Made Backpacks. These items commonly drop off the same enemies.
