Stock up on the good stuff
Materials like Sap, Plant Fiber, Sprig, Dry Grass Chunk, and Pebblets are all considered key materials. They’re used in loads of basic, ever-important crafts like tools, bandages, and the Roasting Spit you’ll need to cook the meat of critters you find on your travels.
It’s a good idea to grab a few stacks of these whenever you can. Storing some in a Basket by your base is a good habit to get into, but if you’re prone to traveling far from your base, you’ll want these on hand so you can quickly grab some grub or set up somewhere to sleep for the night.
