The world of Core Keeper is rich with materials. Ores (Copper, Tin, Iron, Gold, Scarlet, Octarine, etc.) are smelted into bars for tools and armor. Wood and Slime are basic crafting components. Gems (Ruby, Sapphire, Emerald) are used for specific recipes and can be sold. Unique monster drops are essential for crafting boss-tier equipment or summoning items. Always keep an eye out for new resources, as they often unlock new crafting possibilities and progression paths. Efficient resource management is key to success.
