Moonlighter 2: The Endless Vault Perfect Stamp Prices

Shopkeeping in Moonlighter 2: The Endless Vault is a base stamp plus multipliers. You set a gold number on the showcase. The game files that number into Cheap, Perfect, Expensive, or Overpriced. Customers answer with faces. Quality, Deluxe, popularity, furniture, and shop perks then pile on top. This page is the stamp ledger for the relics you will actually see in the first two biomes, plus the rules that make a 21-gold Silence Shell and a 336-gold Blob Shell behave differently on the same shelf. Pair it with the Shopkeeping guide and the Relics Tier List. Vault math sits on Vault unlocks.

Stamps below are Perfect values at baseline quality. They are not the final coins in the till.

Read that table as a ladder, not a shopping list. Kalina Commons live in the 21–89 band. Gallery Commons sit 26–94. The first Uncommons (Blackstone, Electrostar) jump the stamp over 100. Blob Shell at 336 is still Uncommon; it is a warning that color is not the same as a Legendary.

Firewood and Cable Knot share a 42 stamp and do not share a job. Firewood is a Kalina burn tool. Cable Knot is Gallery junk unless a neighbor says otherwise. Battery at 52 is a Gallery cleaner. Starsign Summoner at the same 52 is a Kalina Common you sell. Do not stamp them the same in your head just because the number matches.

Quality multiplier

Each relic has a quality number under the name. Each point is about 5% on the stamp. Ten quality is roughly +50%. Forty quality can more than triple a piece. Tomo’s research can make the multiplier 6% more effective per rarity band and can unlock Deluxe drops that sell higher. Furniture and shop perks add more. The face check still uses the base stamp, not the multiplied till number. If you raise a Silence Shell to 200 because quality made it “feel” Rare, customers will frown and walk.

Practice: stamp Silence Shell at 21, not at 21 plus quality. Let the game add the 5% ticks. If a Known Customer asks for Cheap, go under the stamp on purpose. If a rich unique walks in after you have filled the perk meter, you can test Expensive on a high-rarity piece. Never test Expensive on the first sale of the day; you need smiles to fill the meter.

Calendar hearts

Open the Codex. A six-day calendar forecasts what Tresna wants: a rarity (Uncommon day), a biome (Kalina day), or a similar tag. Popular relics get a heart and a popularity multiplier. On those days, fill showcases with matching stock even if a lonely Legendary is sitting in K33P3R’s chest. A hearted Uncommon at Perfect often beats an unhearted Rare that nobody came to buy.

Plan runs around the calendar when you can. If tomorrow is Gallery day, do not dump every Electrostar tonight at a shrug price. If today is Common day, Silence Shell and Sand Fruit are not jokes; they are the shift.

Faces

Customers talk with icons, not with spreadsheets.

• Gold-eyed grin (Cheap). Too low. They buy, they tip, the perk meter fills, you left coins on the counter.
• Simple smile (Perfect). The band you want. Meter fills. A red stamp marks the top of this band.
• Pained face (Expensive). Some still buy. Meter does not fill. Use after the day’s perks are purchased.
• Angry face (Overpriced). No sale. Drop the number before the next browser arrives.

The Codex remembers reactions. After a few sales you can let the game autofill a known stamp. Until then, start high once, read the angry face, step down. Overpriced is information, not a fine. Two overpriced browses in a row can send a customer out the door, so do not leave a 500 stamp on a 21-gold shell while you AFK at the till.

Perk meter only likes Cheap and Perfect. Open a shift with cheap Commons if you need the first perk fast, then lock Perfect Stamps on Uncommons and Rares. Tips scale with K33P3R upgrades and with furniture from the Countess. Decor from Ms Scratch is cosmetic; it does not change faces.

How to use this with a real bag

1. Identify biome and rarity in the backpack before you take the pendant.
2. Finish Burn / Shock / Absorb chains so quality sits on a sellable relic, not on Aetherium.
3. Stamp from the table. Add nothing for quality; the game already will.
4. Check the calendar heart. Put matching relics on the best showcases.
5. Watch the first face. Adjust once. Log it in your head; the Codex will too.

If gold is the only goal, you are feeding the Vault. If you are still dying to Herald, stop optimizing 21-gold shells and read Getting Started. The till is a loop, not a spreadsheet boss. More tools sit in the Tools Hub.
