Last Z Diamond Reserve Guide: What to Save Diamonds For First
Diamonds are the most important resource in Last Z: Survival Shooter — and the way most players lose their edge is not by failing to earn them, but by spending them at the wrong time on the wrong things. Diamonds are reserve currency, so spend them only when the event or shop value justifies it. This guide breaks down the exact priority order for your diamond reserve: what to protect first, what to spend on second, and which purchases to skip entirely.
Whether you are free-to-play, a light spender, or running a mid-level account, the framework below applies.
What Are Diamonds in Last Z: Survival Shooter?
Diamonds are the highest-tier premium currency in Last Z: Survival Shooter. Unlike basic resources such as food, steel, and fuel, Diamonds cannot be produced in your base or looted from other players — they can only be obtained by completing specific in-game objectives, earning event rewards, or topping up directly.
Diamonds are directly tied to your VIP level. Every Diamond you spend simultaneously accumulates VIP points, which raise your VIP level over time. Your VIP level determines which long-term privileges you can unlock, including your daily Golden Wrench allocation, recruitment resource bonuses, construction speed bonuses, and weekly shop discounts.
This dual function — premium currency and VIP experience — makes every diamond decision more consequential than it looks on the surface. Spending carelessly does not just drain your wallet; it also routes VIP experience toward low-value items instead of building long-term account strength.
The Core Rule: Treat Your Diamond Balance as a Reserve, Not a Spending Budget
The single biggest mindset shift for improving your diamond efficiency in Last Z is recognising that your balance is a reserve, not a spending pool. Most players approach diamonds like a resource to burn. Strong accounts approach them like a strategic reserve to deploy at maximum value moments.
One of the biggest differences between weak and strong F2P accounts is timing. Buying the right item during the right event often matters more than buying more items overall.
The reserve-first framework has three non-negotiable rules:
- Shield money is sacred. Keep a 2,000-diamond reserve by Friday, use 8-hour and 24-hour Alliance Shop shields first when they are available, spend exposed resources before logging off when possible, and shield during real raid risk instead of losing weeks of farming to one bad weekend.
- Never use the direct speed-up button. Never use the direct speedup button. Save speedups for Alliance Duel days to double their value.
- Only spend aggressively during high-value events. Only during Lucky Discounter (40%+ discount) or VIP shop sales.
Priority 1 — The 2,000-Diamond Friday Shield Reserve
Before anything else — before event spending, before shop purchases, before any convenience buy — you need to protect your base every weekend. Always have 2,000 diamonds by the end of the week (or buy in the Alliance store) to spend on shields.
The reason is simple math: Without protection, losing resources sets you back weeks of farming. Shields are more valuable than any purchase. A single unshielded Saturday during Enemy Buster can cost you more progression than any single diamond purchase could buy back.
Use Alliance Shop 8-hour and 24-hour shields with alliance points before spending diamonds. The diamond cost is a fallback, not the first option. Check your Alliance Shop stock every week before Friday. Alliance Shop stock, shield pricing, server war timing, and event pressure can change after updates.
When Is Raid Risk Highest?
The shield reserve rule is anchored to Saturday’s Enemy Buster event, the most dangerous window for resource loss on most servers. For weekly shields during Saturday’s Enemy Buster event. Other high-risk windows include any active State vs. State (SVS) period and coordinated alliance war days. Check your server’s activity pattern before adjusting your Friday reserve downward.
Priority 2 — Key Licenses: Permanent Progression Unlocks First
Once your shield reserve is secured, the next-best use of diamonds is permanent account unlocks that compound every day you play. The top priorities are the key Licenses from the License Store: the Strategy License, Advanced Modification License, and Research License. They permanently unlock core game features, providing a continuous stream of extra resources and speed-ups. This is a one-time purchase for a lifetime of benefits.
Unlike event spending or shop purchases that give you a one-time boost, permanent licenses change your baseline. Every day you play after unlocking them, you benefit. Every day you play before unlocking them is a day of missed compounding.
Priority 3 — All Four Builders
After licenses, unlock all four builders as quickly as possible. It is highly recommended to unlock all four workers. This significantly boosts your construction and research efficiency, dramatically improving the gameplay experience and is a key step towards rapid development.
Your Headquarters level is the ceiling for every other building in your base — and your builders are the engine that raises that ceiling. The level of your HQ determines the maximum level of every single other building in your base. Running only two builders while other players run four is a permanent structural disadvantage that compounds over months.
Priority 4 — Refugee Tickets for Butlers and Scientists
After builders, refugee recruitment is one of the strongest long-term diamond investments available. If there’s one thing you should prioritize your diamonds on right now, it’s gambling for the refugees. You want the Butlers and Scientists. Those should be your priority.
Butlers boost construction speed. Scientists boost research speed. Together they compound every build and research queue you run for the lifetime of your account — making early investment in them exceptionally valuable. Best Last Z F2P spending priority: key licenses first, then all 4 builders, then refugee tickets for Butlers and Scientists, while always keeping 2,000 diamonds by Friday for shields and saving big purchases for discounted events.
Priority 5 — Lucky Discounter Event Budget
Lucky Discounter is the most efficient recurring diamond-spending event in the game for F2P and light-spend accounts. The key is preparing diamonds in advance, not reacting to it when it opens. The most important part of Lucky Discounter is that several attempts are fixed, not random. Those guaranteed 90% discounts are what turn the event from maybe useful into one of the best badge-buying opportunities in the game.
The guaranteed 90% discounts happen on attempts 5, 9, 18, and 32. These are fixed checkpoints and do not depend on luck. Your ticket and diamond strategy should be built around reaching at least attempt 9 before the event ends.
Save at least 9 tickets for two guaranteed 90% attempts. 18 tickets is a stronger long-term target, and 32 tickets is the maximum-value plan for very patient players.
What to Buy in Lucky Discounter
For most players, badges are the best purchase because they feed long-term research and progression instead of short-term convenience value. Never buy speedups below 90% discount — VIP shop prices are similar or better.
Lucky Discounter follows a consistent weekly rotation: Gacha Go → Bullseye → Lucky Discounter → Lucky Chest. Plan your ticket and diamond accumulation around this four-week cycle.
Priority 6 — Gacha Go for Golden Wrenches
Gacha Go is a recurring diamond-spending event that rewards Golden Wrenches, Modification Blueprints, and gift boxes. Golden Wrenches are essential for vehicle modification and unlocking powerful vehicles like Hercules.
You need 10,000+ Golden Wrenches for max vehicle level. This event is the fastest way to collect them. A good target is 30,000–55,000 diamonds to accumulate enough keys for the 300-key bundle. As with Lucky Discounter, the critical rule is to decide your budget before the event opens — not once you are already spending.
Weekly Shop Diamond Priority — What to Buy Every Week
Outside of events, your weekly shop routine determines how efficiently you convert small amounts of diamond-adjacent currency into long-term progression. Here is the current priority order validated for 2026:
| Shop | Buy First | Skip |
|---|---|---|
| Glory Shop | Orange Hero Fragments, Golden Wrenches, Framework Fragments | Modification Blueprints |
| VIP Shop | Golden Wrenches (10 per week) | Speed-ups bought directly with diamonds |
| Merit Shop | Power Cores and Orange Fragments (SVS only) | Purple Equipment Boxes, Basic Tickets, Resource Crates |
| Camilla’s Shop | Advanced Modification License first, rare vehicle materials second | Common speed-ups |
Glory Shop: Orange Hero Fragments first, Golden Wrenches second, Exclusive Framework Fragments third, Random Components fourth. Enhancement Alloy and Refugee Tickets when points remain.
Golden Wrenches are the core VIP Shop purchase. Their value peaks during Vehicle Boost or upgrade rush events, making them essential for quickly leveling your modified vehicle.
The Arena Diamond Trap: How to Use It Without Wasting Diamonds
The Arena is both a free diamond source and one of the most common diamond sinks in the game. Used correctly it earns you diamonds; used incorrectly it drains your reserve faster than almost anything else.
The Arena is a massive trap for the impatient. Buying extra attempts gets expensive — the price jumps from 50 all the way to 800 diamonds per hit. If you go overboard, you could blow over 11,000 diamonds a week just on Arena tickets.
The correct approach: use your 5 free daily attempts, use the free refresh to find opponents you can beat, collect your rank rewards, and stop. Accumulating wins in the Arena and finishing higher in League standings at the end of each season both yield Diamond rewards. The reward is in the weekly ranking, not in purchasing extra attempts.
What to Skip Entirely: The Anti-Waste Rules
Knowing what not to spend diamonds on is as important as knowing what to buy. These are the confirmed waste categories:
- Direct speed-up button. Never use the direct speedup button. This is the worst diamond trade in the game — you get a one-time timer reduction that you could replicate for free by saving speed-up items and using them on Alliance Duel days.
- Random daily chest opening. Use chest saving as a bonus diamond strategy, not a daily income plan. Trickle-opening reduces your odds at jackpot results.
- Purple Hero Fragments. Ordinary Purple Hero Fragments have low long-term value and are not recommended.
- Power Cores outside of SVS. Skip speed-ups bought directly with diamonds and Power Cores. You can earn 150–250 Power Cores weekly through normal events, making direct purchases wasteful at any standard spending level.
- Extra Arena attempts above the free five. The escalating cost (50 → 100 → 200 → 400 → 800 diamonds per attempt) makes this a fast way to drain your weekly reserve for minimal ranking gain.
How to Farm Free Diamonds Consistently
Building a healthy reserve is impossible if your income is unpredictable. F2P diamond income comes from many small and medium sources rather than one jackpot system. Here is the complete income stack to optimize every week:
Daily Sources
- Daily tasks / 150-point goal. You should never miss the 150-point goal. The final Golden Chest you get for hitting 150 points is the most reliable way to build your diamond stash. Points accumulate from training troops, killing zombies, and upgrading buildings.
- Fury Lord (4x daily). The Fury Lord is a giant boss that spawns near Level 6 cities four times a day. Most people hit it once and walk away — that is a waste of resources. You get 4 attacks every day, and you should use all of them. After your fourth hit, the game gives you five fuel cans back.
- Explore Treasure, Canyon Clash, and Battlefield Breakout. Make sure you are checking off your daily chores every single day: Explore Treasure gives easy diamonds, Canyon Clash and Tyrant reward consistent output, and Battlefield Breakout delivers diamonds alongside combat rewards.
Weekly Sources
- Alliance Duel. Each week, you can unlock 9 reward chests packed with valuable rewards. Researching Alliance Recognition literally doubles your rewards from the Duel chests. This is one of the highest-leverage free-diamond upgrades in the game.
- Arena rank rewards. Gold or higher Arena rank earns 1,000–5,000 diamonds weekly.
- SvS diamond mines. When the SvS heat kicks in, make sure your alliance is gunning for the capital. If your server wins, the area around the capital spawns Diamond Mines.
- Hero Battlefield Campaign. Participating in every reset of this event rewards Golden Wrenches, Universal Orange Fragments, Glory Badges, and Diamonds. Top-ranked players finishing in positions 1 through 10 can earn upward of 5,000 Diamonds along with elite hero fragments.
One-Time and Spike Sources
- Fury Lord achievements. Completing this achievement series unlocks Diamond rewards directly. These are largely one-time milestones, making them especially valuable in the early game when pushing through them quickly can build a meaningful Diamond reserve.
- Bulk chest openings. Bulk opening does not change the odds per chest, but it gives more chances at rare drops. Realistic expectations: approximately 20,000 diamonds total (including 10,000 and 5,000 jackpots) from saving thousands of chests, but this required weeks of accumulation.
- Redeem codes. Florere Game releases new codes every few weeks to celebrate game updates or social media milestones. Codes expire fast — some only last for a week, and many have a 200,000-user limit. Use the official portal at last-z.com/giftCenter and redeem immediately.
The Monthly Pass: Best Value for Spenders at Any Level
If you are spending any real money in Last Z, the ApocaAid Monthly Pass is the starting point. For the following 30 days, 500 Diamonds are delivered to your account every day, alongside bulk speed-up items and one daily Trade opportunity — which has a high probability of yielding Golden Wrenches, Diamonds, or hero fragments. The 30-day cumulative output of the Monthly Pass far exceeds its purchase cost, making it the single highest-value top-up option for long-term players.
VIP Level 10: The Diamond Milestone That Changes Your Hero Ceiling
There is one specific VIP milestone that every account should plan toward: VIP Level 10 is a particularly important milestone — reaching it unlocks the ability to purchase Versatile Orange Fragments from the shop, which are the core material for star-upgrading top-tier heroes.
These fragments are the only way to upgrade the best heroes in the game without spending money. This makes VIP Level 10 a hard milestone for any serious F2P account, and it reinforces why routing diamond spending through high-value channels (rather than low-value conveniences) matters — every diamond spent at good value also builds VIP experience.
How Alliance Recognition Research Changes Your Diamond Economy
One of the most leveraged investments in the entire game is completing Alliance Recognition research — and it directly improves your diamond income, not just your stats. Alliance Recognition delivers massive stat boosts, contributes directly to Alliance Duel points, and unlocks monthly ranking rewards including up to 10,000 badges for top-tier placements. That structure means the tree both costs badges and generates them at competitive levels.
Researching Alliance Recognition doubles your rewards for all nine weekly Alliance Duel chests. Because Alliance Duel chests are one of the main recurring diamond and badge sources in the game, this research multiplier compounds every single week.
Diamond Reserve Planner: A Simple Weekly Checklist
Use this checklist every week to keep your reserve healthy and your spending disciplined:
- ☑ Complete the 150-point daily task every day for Golden Chest drops
- ☑ Use all 4 Fury Lord attacks daily (collect fuel can refund on the 4th)
- ☑ Complete Arena daily free attempts, collect weekly rank reward
- ☑ Confirm Alliance Shop shield stock before Friday reset
- ☑ Verify your balance is at or above 2,000 diamonds by Friday evening
- ☑ Check the weekly event rotation — is it a Lucky Discounter or Gacha Go week?
- ☑ Buy Glory Shop priority items (Orange Hero Fragments first)
- ☑ Buy VIP Shop Golden Wrenches (10 per week)
- ☑ Check for new redeem codes via the official Gift Center
- ☑ Do NOT press the direct speed-up button under any circumstances
Early Game vs. Mid Game vs. Late Game: How Diamond Priorities Shift
Early Game (HQ 1–20)
Diamonds are valuable. Don’t waste them on speeding up timers or random chests. Save for: guaranteed hero summons, important events like Lucky Discounter, and VIP upgrades. In the early game, focus entirely on the 2,000-diamond shield reserve, key licenses, and your first two builders. Every permanent unlock you secure now reduces the grind for the rest of your account’s life. Check out the Last Z Beginner Guide for more tips during this stage.
Mid Game (HQ 20–30)
By this stage, your permanent licenses are active and you should have all four builders running. During mid-game development, focus on your chosen core hero and target their S1 Deeds or exclusive equipment packs. Simultaneously, actively participate in events like Lucky Discounter. Refugee tickets for Butlers and Scientists become the primary diamond target, and your Lucky Discounter budget should grow as your reserve builds.
Late Game (HQ 30+)
Late-game accounts redirect diamond reserves toward Gacha Go (Golden Wrenches for vehicle progression), badge acquisition via Lucky Discounter, and SVS preparation. The player who enters Lucky Discounter with 30,000 diamonds and a plan leaves with 15,000+ badges and a month of discounted speedups. The player who spent those diamonds on convenience between events gets neither.
