Vendors

There are a handful of vendors in Umbra.

BROKERS
Brokers deal in byproducts (minerals not used in fabrication) and broken equipment. They pay 1 credit per gram for Aggregate, Rock-Salt, and Pyrite, ensuring no one will ever be truly broke in Umbra. When your gear inevitably breaks, you can pay 250 credits per item to have them salvaged, which will return a small amount of minerals. Usually it's just byproducts, but occasionally, you'll get something useful.

They also offer daily missions for these stones which can pay more or less than 1 credit per gram, but also offer XP and faction points.

Brokers are found in The Gravel Pit (near the North Drillship Terminal) and The Slag Heap (near the West Drillship Terminal), and are accompanied by two smaller drone bots that refine or fuse collectible gemstones.

WANDERING VENDORS
There are two vendors who wander the fabrication zones. The sell only octarine gas and Power Cell contracts, but will buy any curios or refined gemstones you don't want, and that you don't wish to trade.

STATIC VENDORS
There are two, one near the Northern Drillship terminal, and one near the Nautilus Corp. Count House. They exchange research points for sell clothing and collectible cards, and will also buy any curios or refined gemstones you don't want.

THE UPLINK
The Uplink is not a vendor, but a purchasing system available to all miners at all times, by hitting U on your keyboard, or an icon on the display. Open it to use your credits to buy mining tools, tool augments, consumables, boosters, and fabrication items, or to trade in your Udarniks for rewards.

You can use the Uplink to purchase tokens, which in turn can be used there to purchase unidentified curios, unrefined gems, advanced gear and augments, pre-made fabrication ingredients, or to upgrade to a pro account.
