Economy: Diamonds, Shops, Plunder

🗓 Updated: 2026-09-03

Last Asylum: Plague runs three parallel economies: diamonds and shops, daily plunder, and the event calendar. Each has its own traps — bad diamond buys, wasted plunder capacity, stamina spent at 5% efficiency. This page is the community consensus on all three, with the exact numbers.

VIP Shop: Diamond Priorities

The VIP shop takes diamonds, and most of its stock is a bad trade. The verified buy list:

And the full rule: avoid everything else unless extreme necessity. The shop is priced to tempt impatient players into converting diamonds into items the game gives away through events — hold the line.

Shop Restock Schedule

All shops restock on Monday. Plan your week around it: buy out your priorities Monday when stocks are full, run your Alliance Duel and Expedition income mid-week, then spend the weekend deciding what Monday’s refresh owes you. Players who shop on Sunday buy a picked-clean shelf.

Sanctuary Shop

1. Crow Essence and UR Hero Omnifragments — buy to the maximum.
2. Antidotes and SSR Omnifragments.
3. Gear Stones and Recruitment Tickets.
4. Skill Badges and SR Omnifragments — extra budget only.

Expedition Shop

1. UR Omnifragments and Essences.
2. Expedition Chest, Inscription Fragment, and the UR Inscription Chest.
3. Antidotes and Gear Stones.
4. Speedups, Tickets, and the 100K Crow Fruits — necessary only.

Honor Shop

1. UR Gear Blueprint, Essence, and UR Omnifragments.
2. Curiosity Chests and UR Inscriptions.
3. Everything else — urgent needs only.

The critical rule for Honor specifically: honor is only for gear blueprints. There are no epigraph chests here — that is not an oversight to work around, it is how the currency is designed. Spend honor on UR gear blueprints first and treat the rest as filler.

Alliance Shop

1. UR Hero Omnifragment, Crow Essence, and Direct Relocation.
2. Crow Evolution Guide, Shields, SR Inscription Chest, and Bella Fragments.
3. Optional: all speedups.

Epigraph Chests: The Exception Rule

Buy epigraph chests in every shop except the Honor Shop. Epigraphs feed the Raven system, and the Raven’s UR epigraphs only buff one faction — in the mono-faction meta, that makes epigraph chests the single most consistent long-term purchase in the game.

Free-to-play epigraph income is real, if you show up for it: 30 UR shards per day from Alliance Duel, plus self-forging in the Epigraph Workshop, adds up to roughly 1.5 UR epigraphs per month. The full system — workshop levels, promotion order, and rarity rules — is covered in the Raven guide.

Diamond Rules: Wheels, Banners, and Milestones

1. Save until day 8 for the Cynthia Wishing Wheel — she runs about 11,500 diamonds. Spin 10x only; single spins pay the same odds at a worse price.
2. After day 15, save for Joker’s wheel — the UR PvP finisher event. The mid-game diamond reserve exists for this.
3. Never dump diamonds into standard recruitment. Wait for rate-up banners — same currency, better heroes.
4. Do not chase cumulative diamond-spend milestones like Deep Sea’s Gift. Spending diamonds just to cross a reward threshold is buying the milestone, not the value.

Best Packs ($20-200 Range)

If you spend at all, the community picks three packs in the $20-200 range: Universal Speedup packs, Raven Essence packs, and City Level-Up packs. And from the beginner guides: the $1 Marlena top-up at day 66 remains the single best value purchase in the game at any price.

Plunder: The Complete Mechanics

Plunder income is capped by a daily limit, and the limit scales with your Sanctuary level. Knowing the thresholds changes when you stop attacking for the day.

How the Limit Works

• The limit counts Grain, Timber, and Herbs carried home from attacks.
• Below the limit: you carry resources at 100% efficiency.
• From 1x the limit: efficiency drops to 15%.
• From 1.3x the limit: efficiency drops to 5% — that is the floor.
• The limit resets at 02:00 UTC daily.
• The yellow triangle under a target’s Might is the over-limit indicator — check it via Effect Overview, then Plunder Gains.

Daily Limits by Sanctuary Level

The pattern: +1M per Sanctuary level up to 20, then +2M per level to the 30M cap at Sanctuary 30. Two mechanical notes:

• A Sanctuary upgrade raises your limit immediately — no reset wait. If you are near the daily cap and a Sanctuary level is close, finish it first and plunder after.
• The War Supply skill from the Legion Commander specialty tree (Era of Revival) raises the cap by +6 / +14 / +24 / +36 / +50% at skill levels 1-5. See the Era guide.

The Nine-Hit Rule

Never attack the same farm more than nine times in a row. The tenth hit destroys the city outright and teleports its owner away — you lose the farm, and the player loses their city. Nine hits is the ceiling; the community treats it as an obligation, not a suggestion.

Stamina Math: Why Over-Limit Plundering Fails

Spending stamina on over-limit plunder is one of the worst trades in the game:

• At 15% efficiency, each stamina point earns roughly 7x less than normal.
• At 5% efficiency, roughly 20x less.
• The same stamina spent on monsters earns full value regardless of your plunder status.

So the daily rhythm writes itself: hit the richest targets you can beat first while you are at 100%, stop attacking farms the moment you cross the limit, and dump the rest of your stamina into monsters. And within your plunder window, always hit the richest target first — the limit is coming regardless, so fill it with the biggest numbers available.

Caravans and Covert Ops: Always Run Both

Caravans and Covert Ops are separate systems from plunder, and they dodge every restriction above: no plunder limit, no real troop loss, no stamina cost. They are pure upside, which is why the community rule is to run both every single day.

• Caravans — your automated trade income. Keep them moving.
• Covert Ops — you can plunder up to 5 other players’ Covert Ops per day. Golden Covert Ops pay the best rewards — always grab a golden one when you see it.
