Currency and Payment

  • General currency: Skeleton Coins are explicitly described as a basic currency of Lynn’s world, usable as a general medium of exchange 4.
  • Physical circulation: Customers carry coins in pouches and pour them onto the apothecary counter to pay for treatment 5 6.
  • System accounting: Lynn’s status panel records his personal Skeleton Coin balance, while purchases trigger deduction notifications 2 23.
  • Alternative payment: Bloodsaw Maniac instructs Lynn to accept something of equal value from customers without money. Lynn takes Blood Doll’s right eye as payment and allows her to redeem it after earning money 2 4.
  • Separate shop funds: The apothecary’s regular customer payments belong to the shop; Lynn initially cannot spend them as his own money. His system quest rewards are personal funds 4 22.
  • Direct transfers outside retail purchases: Information Agent No. 24 receives Lynn’s consultation and messenger-hiring payments through direct transfers, with the two fees charged separately 82.
  • Gifts, wages, and inducements: Lynn offers Skeleton Coins and discount coupons to the Twin Ghostly Shadows to persuade them to accept treatment. He later pays Blood Doll one coin for assigned work, offering the possibility of doubling her pay 153 1001.
  • Bribery: Skeleton Coins can purchase cooperation from hostile creatures. Lynn uses them to obtain transport, information, and access to classified cargo from Flesh God Cult members 900 901 902.
  • Physical gains and losses: The system records changes caused by handling actual coins, not only formal purchases. Zuo Zuo swallowing a Black Skull Coin produces a 1,000-Skeleton-Coin deduction, while Lynn recovering coins from her produces balance-increase notifications 513 514 515.

Bribery and Coercive Transactions

Flesh God Cult Transport and Information

Lynn combines threats, a demonstration of force, and coin payments to gain entry to a Flesh God Cult transport. The cultists’ hostility gives way to claims of brotherhood once they accept his money. He then purchases information about their summoning mission and access to the Parasite Beast cargo destined for Blue Star 900 901 902.

Payment Amount Result
Payment for a slain Tentacle Guardian’s life 20 coins Lynn tosses the coins into another tentacle’s mouth after shooting the guardian; the one-eyed monster later claims the cult would have killed it for ten 900 901
Ride aboard the moving mass of flesh 100 coins The one-eyed Tentacle Monster accepts the money and welcomes Lynn as a fellow sect member 900 901

Identification of the destination world 50 coins The monster names No. 47 Ocean World, which Lynn recognizes as Blue Star 902
Information about the shipment’s purpose 100 coins The monster explains that believers requested the cargo to accelerate the world’s corruption 902
Access to the classified Parasite Beast cargo 300 coins The monster immediately reverses its refusal and orders preparations for Lynn’s inspection 902
Further Parasite Beast development information 50 coins The monster explains the ordinary three-to-five-day incubation period 903

After subduing the cultists, Lynn reclassifies his earlier payments as a loan. He claims to have lent 890 Skeleton Coins, rounds the principal up to 900, imposes interest of 200% per minute, and demands a total of 11,700 coins. Zuo Zuo realizes that he had intended to recover his spending with interest from the outset 910 911.

Buying Cooperation at the Occupied Apothecary

  • Lynn halts a hostile Flesh Humanoid’s knife attack by placing a Black Skull Coin on the counter, then scatters additional Skeleton Coins and asks whether it will become his “dog.” The creature immediately barks, and its attitude toward him improves dramatically 927 928.
  • The Black Skull Coin also persuades the cult’s captains that Lynn is an exceptionally wealthy customer. They order their subordinate to serve him carefully in pursuit of repeat business 929.
  • The two Flesh Humanoids discuss receiving fifty percent of the proceeds from the establishment’s business and declare that they have never seen so many Skeleton Coins 928.

Hoarding, Recovery, and Destruction

Lynn’s Hidden Savings

  • Zuo Zuo reveals that Lynn conceals coins in his mask, clothing, belt, shoes, and shorts. He also hides savings beneath floorboards in his Dark Night City room and beneath the bedroom floor at the Potion Shop 512.
  • At least two thousand coins are hidden beneath the second floorboard by his Dark Night City bed; the denomination of that particular stash is not specified 512.
  • Sir Awen later identifies another hiding place beneath the second layer of stone slabs in the corner of Lynn’s room, where Black Skull Coins are stored with treasured books and comics 2049.

Zuo Zuo’s Coin-Eating Incident

Zuo Zuo attempts to break Lynn’s curse-induced loss of fighting spirit by threatening his savings. She chews and swallows Black Skull Coins, causing repeated deductions of 1,000 Skeleton Coins. Her threat to devour his entire fortune and digest it with acid finally drives him to use Limited-Time Curse Removal on himself 512 513.

Lynn subsequently retrieves coins from Zuo Zuo before she can digest them. Recorded recoveries include batches of two, eight, and five Black Skull Coins, alongside other swallowed items. By the end, the recovered Black Skull Coins and Skeleton Coins exceed the amount she had visibly eaten during the incident, exposing additional concealed appropriation of his savings 514 515.

Big Tongue’s Concealed Earnings

Big Tongue initially offers roughly a hundred Skeleton Coins as proof of loyalty after Lynn discovers his cooperation with the Flesh God Cult. Under pressure, he repeatedly reveals larger amounts while blaming poor arithmetic for his earlier claims 935 936.

Disclosure Recorded Gain or Amount Explanation
Initial offering Roughly a hundred coins Big Tongue claims to have saved all his earnings for Lynn 935
Supposed final remaining coin +1 Skeleton Coin He insists that nothing remains afterward 935

Second substantial additional disclosure +12,100 Skeleton Coins He claims to have omitted two zeroes 936
Cellar stash Amount not specified Lynn exposes further hidden coins by kicking an empty bottle into the cellar, then confiscates the stash and completes the hidden quest concerning Big Tongue’s secret wealth 936

Other Recoveries and Losses

  • Looted funds: While dealing with the Flesh Humanoids occupying his shop, Lynn obtains one Black Skull Coin and 321 Skeleton Coins among other recovered items 932.
  • Destroyed stock: As the Hell Walker breaks potion bottles in the apothecary, Lynn mentally associates the losses with values of 100, 500, and 821 Skeleton Coins 56.
  • Deliberate destruction: Silver Fantasy scatters Black Skull Coins bearing engraved signatures and dates, then burns them in intensely hot flames until they melt down into ashes 2052.
