Resources are TUSG.io’s material economy: monsters drop ores, biomes grow plants and pool liquids, and crafting turns the pile into gear. Knowing what is actually rare is the difference between a full vault and a valuable one.

Ores drop from monster kills — but only from level 3 and higher monsters, so farming fodder feeds your mass, not your ore stock. Higher-level monsters drop more per kill, and boss variants multiply the count (golden bosses drop 3×).
Liquids are biome-locked pools you collect on site: Aetherspring and rare Solmead in the normal biome, Pyrebrine in the hot, Voidbrine and Mirefen in the cold. See the biomes guide for the full geography.
Bank the top of the ore table (Aetherium, Valorium) and every liquid — they gate the recipes that matter. Common ores in bulk are marketplace inventory: sell them to crafters and let someone else do the hauling. Use bank vaults so a bad death does not liquidate your savings.
