Economy

Money takes up space here. Put it somewhere safe before a trip that has no shopping on the itinerary. I learned this while carrying a very respectable balance into an entirely unrespectable swim.

Currencies

Brindas icon

Brindas

I find Brindas most reliably on the recently dead, though they turn up elsewhere too. They pay for settlement goods, taxis and other services; I check the listed currency before carrying a bag of the wrong money across the island.

The name comes from Brinda, Spoonkid's fish dealer, church founder and habitual gambler. The resulting banking system is about as stable as that history suggests.

Form: physical custom currency

Aliases: Brin, $B

Uses: Monument vending, taxis, and other island services configured to accept $B.

Gemstones icon

Gemstones

I've found Gems while mining, warm to the touch and vibrating like a cat's purr. Exposed ones all seem to look green. I keep them for the Gem Dealer, the Apprentice and the rarer services that ask for them, checking the current shelf before spending the last handful.

Form: physical custom currency

Aliases: Gems

Uses: Gem Dealer rotations, blueprint packages, the Apprentice's fixed offers, and rare services.

Scrap icon

Scrap

Scrap still pays for useful work: research, recipes, trade and services. I keep some aside before taking a risk that needs none of it. We have acquired more currencies since Scrap ruled the island, and consequently more kinds of money to argue about.

Form: physical item

Uses: Ordinary trade, research-related losses, marketplace listings, services, and many recipes.

What to save

A wild Gemstone lying on pale rock

Keep the return fare and the materials for your next recipe before selling the rest.

A freshly mined Gemstone belongs to its miner until collected. Their direct, accepted mutual-feud opponent can collect it too; being a teammate does not grant that right. Other pickup attempts leave it on the ground. Once an eligible collector receives it, ordinary trade, dropping and storage apply.

Gem Dealer

I check the Dealer's shelf before spending Gems on the first impressive object. His small selection rotates through eligible blueprints, armor, books, packages and other curiosities. Find him with the Apprentice at Bandit Camp or Outpost; both compounds share stock, rotation and purchase allowances.

The Gem Dealer's rotating eight-offer shop interface
Check today's shelf. The possible-stock list below includes offers that may not be available now.

A physical blueprint goes home in the bag. A package teaches its contents immediately; I read which I am buying before paying. Call Gem Stock for current offers and prices, or browse eligible delivery goods on a personal Island Computer. Immediate-learning packages require a visit. Keep weapons lowered around the security.

Use: Find the dealer compound, inspect the current board, and bring Gemstones.

Cost: Gemstones

Possible stock is the complete eligible catalog, not today's shelf. 8 offers appear per rotation, which changes every 2 real hours.

Both compounds share rotation, stock and purchase limits. Blueprint packages teach their listed blueprints immediately and are bought in person.

Direct blueprints can be bought even if already known. Computer delivery adds one Gem to eligible Dealer goods; packages remain in person.

The Apprentice icon

The Apprentice

When I need a known tool, I check the Apprentice instead of waiting for the Dealer's rotation. His permanent counter at Bandit Camp and Outpost stocks practical devices and encounter equipment. Its selling offers buy Blueprint Fragments, Blueprint Pages and Blueprint Books for Gems. Check the required amount: the fragment offer takes three at a time.

The Apprentice's four equipment offers and separate Sell Fragments tab
The pictured counter separates buying equipment from selling blueprint materials. Check the selected tab and current quantities before confirming.

Read the SOS beacon or air-support instructions before using the equipment. The purchase itself is the quiet part.

Use: Speak to the Apprentice at the Gem Dealer compound.

Cost: Gemstones

The equipment counter is permanent; Sell Blueprint Items is a separate tab. Each sale needs the listed quantity of its blueprint item.

These are in-person trades. The stock report describes the rotating Dealer, not a new Apprentice rotation.

The Apprentice's complete counter
Item Trade Gem payment
Cloned SOS Beacon Buy 1 Pay 15 Gems
AN/PEQ-15 Target Designator Buy 1 Pay 20 Gems
AC-130 Beacon Buy 1 Pay 30 Gems
Island Phone Buy 1 Pay 3 Gems
Blueprint Fragment Sell 3 Receive 1 Gems
Blueprint Page Sell 1 Receive 4 Gems
Blueprint Book Sell 1 Receive 10 Gems

Operating instructions: Island Phone · Cloned SOS Beacon · F-15 designator · AC-130 Beacon.

The Apprentice buys Blueprint Fragments, Blueprint Pages and Blueprint Books. Check the quantity in each offer and keep the knowledge materials you still need before clearing a stack.

Monument Vending icon

Monument Vending

I check the settlement counters before searching another crate for one missing tool. Different shops carry building supplies, food, farming equipment, vehicle parts, diving gear and weapons. The location matters as much as the machine: one counter cannot promise another's stock. The trading guide puts the currencies and merchants together for planning a supply run.

Use: Read the machine and its location; different counters carry different work.

Cost: Usually Brindas

Stock is shared, and some arms offers rotate. Yesterday's shelf may have changed.

Marketplace Delivery icon

Marketplace Delivery

The marketplace lets me sell beyond the people I can meet in a day's travel. Purchases arrive through the drone network, so the order still has a physical journey to complete. Check the quoted trade and delivery terms before paying; the mail and delivery guide covers the other ways to get an item across the island.

Use: Use a participating market terminal and leave room for the delivery.

Cost: The listed price and delivery terms

Black Market Buyer

Look for the Black Market Buyer when deciding what to do with a recovered Car Radio, MLRS Aiming Module or Cobalt paperwork. His counter pays physical Brindas. The Outpost and Bandit Camp buyers accept radios only; other equipped counters can buy the additional goods. Check the selected quantity before selling.

Approach the buyer and interact within 6 metres. Sell one item, ten, or all matching carried items.

Outpost and Bandit Camp buyers accept only car radios. Other buyers also accept MLRS modules and the two named Cobalt documents.

Cosmetic skins do not change acceptance. Cobalt paperwork must have the exact named document title; ordinary paper does not qualify.

Black Market Buyer payments
Sell one Receive Brindas Where accepted
Car Radio 120 Every buyer
MLRS Aiming Module 700 Outside Outpost and Bandit Camp
Cobalt Recovery Claims 25 Outside Outpost and Bandit Camp
Cobalt Route Docket 35 Outside Outpost and Bandit Camp

Shopping from home

Order through the Island Computer's Shopping pages. An eligible personal terminal needs a suitable Mail Terminal with room for the whole purchase. Eligible checkouts can count currency in carried backpack contents too.

Selling a material is easy; remembering which recipe needed it is harder. Consult the recipe list before turning an unfamiliar ingredient into somebody else's bargain.
