How to Get High-Tensile Spidroin in Starfield

In Starfield, High-Tensile Spidroin can be harvested primarily from the Frigid Palm plant found in the Linnaeus System on the planet Linnaeus II. Additionally, certain vendors, like Jemison Mercantile, UC Exchange, Zuri's Essentials, and Denis Averin occasionally have High-Tensile Spidroin in stock.

Harvesting

The most efficient way of getting High-Tensile Spidroin is by harvesting it from a plant known as the Frigid Palm. The Linnaeus System, particularly the Linnaeus II planet, is abundant with these plants. To harvest High-Tensile Spidroin, land on a spot in the Frozen Mountains region of Linnaeus II. Once there, look out for tall plants that look like cactus. When you find the Frigid Palm, scan it, and you will be prompted to harvest.

Buying

You can also buy High-Tensile Spidroin from specific vendors, but finding High-Tensile Spidroin in stock is pretty rare. Two main vendors are the Jemison Mercantile located in New Atlantis (Alpha Centauri) and Denis Averin in Cydonia (Sol). There is no guarantee they'll have it when you visit them, and stock is very limited even if vendors have High-Tensile Spidroin for sale. However, as you level up, the availability of rarer materials like High-Tensile Spidroin in shops increases.
