Your Essential F2P Diamond Strategy in Last Z

Maximizing your free-to-play experience in Last Z hinges on smart diamond management. This guide outlines how to acquire, save, and spend your valuable diamonds for optimal account progression. The fundamental principle is prioritizing long-term growth and defense over fleeting convenience purchases.

The Core Diamond Principle

Free-to-play progress thrives when diamonds are invested in permanent account enhancements, not momentary boosts. Always maintain a minimum 2,000 diamond safeguard for weekly shield coverage. Purchase shields from the Alliance Store using alliance points first, and only allocate surplus diamonds to refugee recruitment, high-value event deals, or upgrades that offer lasting value.

Quick Diamond Rules

• Weekly Shield Fund: Ensure you possess 2,000 diamonds by Friday.
• Refugee Vouchers: These provide the fastest route to growth boosts (especially Butlers and Scientists).
• Lucky Dealer Event: Reserve diamonds for genuine discounts, not impulsive buys.
• Discounted Accelerators: Only acquire these when the value is exceptionally clear.
• Avoid Impulsive Spending: Never use diamonds simply because they are available.

Earning Diamonds Without Spending

Consider free diamonds as a regular income rather than a random bonus. Regular participation in the Arena, various events, Furylord battles, using redeem codes, and opening saved chests all contribute to replenishing your shield fund and generating extra diamonds for growth-focused purchases.

Consistent Diamond Sources

Weekly and Event Rewards

• Arena Rankings: Achieving Gold tier or higher awards 1,000-5,000 diamonds weekly.
• SVS Personal Rewards: Diamonds are often included in the first three personal reward boxes during State vs. State events.
• Alliance Skirmish: Daily chest completion provides rewards.
• Promotional Codes: Active codes frequently grant free diamonds.
• Event Milestones: Most special events include diamonds as threshold rewards.

Maximizing Furylord Battles

Furylord appears four times daily at 00:00, 06:00, 12:00, and 18:00, except on Sundays. Employ these tactics:

• Use All Attacks: Even without full fuel, use fuel containers (you'll recover 5 from rewards).
• 3 Million Damage Objective: This milestone unlocks superior A-tier purple gear through achievements.
• Faction Bonus Timing: Attack during your faction's 50% damage bonus day to maximize achievement progress.
• Highest Single Hit: Only your highest damage hit counts towards achievements, so focus on one powerful attack.

Free-to-Play Diamond Spending Priorities

Before any diamond purchase, ask yourself three questions: Does it protect my base, offer a permanent speed boost, or align with a high-value event? If the answer is no, keep your diamonds.

Tier 1: Essential Acquisitions

1. Weekly Protection Reserve
   • Always maintain a 2,000 diamond minimum by Friday.
   • A better initial approach is to acquire 8-hour and 24-hour shields from the Alliance Store using alliance points when available.
   • Protection is more critical than spending on random upgrades.
   • Priority: Keep this reserve untouched before considering optional event purchases.
2. Refugee Recruitment Permits
   • This is the fastest method to accelerate construction and research speeds.
   • Target: Butlers (for construction) and Scientists (for research).
   • Refugees provide permanent speed bonuses.
   • Top Priority: Crucial for long-term account development.
3. Lucky Dealer and Strong Event Deals
   • Spend only when event value significantly surpasses standard shop rates.
   • The Lucky Dealer is among the most effective diamond events if you are prepared.
   • Spending on low-discount items is generally less efficient than waiting for better deals.
4. Discounted Accelerators Only
   • Never use the direct accelerator button.
   • Only buy accelerators when the discount is substantial enough to offer clear value.
   • Save accelerators for event days whenever feasible.
   • Convenience spending is typically the biggest diamond drain.

Tier 2: High-Value Acquisitions

• Lucky Dealer Accelerators: This event recurs approximately every four weeks. Acquire accelerators at 40%+ discounts only. Building and research accelerators are the highest priority.
• VIP Store Discounted Accelerators: Check the VIP store for sales. Buy only when the discount is significant.

Optimal Shops for F2P Players

Shops are vital for converting limited currencies into sustained account power. For free-to-play players, the best shops are those that consistently translate your efforts into irreplaceable progress.

VIP Store

• Buy: Golden Wrenches (critical for vehicle modifications, especially during Vehicle Boost events) and Discounted Accelerators (when available at good prices).
• Avoid: Power Cores (unless during specific events, as up to 500 are free weekly from the Tyrant event) and full-priced accelerators.

Time-Limited Shop

• Buy: All Badges (essential for high-tier upgrades) and Versatile Orange Fragments (unlocked at VIP 10, offering premium value). Also, gem-purchased items with favorable value.
• Avoid: Items with poor diamond-to-value ratios.

Glory Shop

• Always Buy: Versatile Orange Hero Fragments, Golden Wrenches (5 weekly), Equipment Framework Fragments (when available), and Random Component Boxes (when available).

Merit Shop

• Note: This shop is always accessible. Valor Medals, its currency, are earned from SVS, Saturday's Buster Day (Alliance Skirmish), and Canyon Clash.
• Buy: Power Cores (prioritize during events) and Versatile Orange Fragments.
• Avoid: Purple Equipment Boxes (low return on investment) and Basic Resource Crates (low value).

What to Never Purchase

Worst Diamond Investments

• Direct Accelerator Button: Considered one of the worst trades in the game.
• Purple Equipment Boxes: Offer low long-term value.
• Basic Recruitment Permits: Provide poor return on investment.
• Resource Selection Crates: Can be acquired for free through gameplay.
• Ordinary Purple Hero Fragments: Low long-term value.
• Power Cores (outside events): The Tyrant event provides up to 500 free weekly.
• Full-priced Accelerators: Wait for Lucky Dealer discounts.

Strategic Account Development

Growth-First Approach

One free-to-play player reached Shelter Level 28 with minimal real-money investment by following this strategy:

• First 4 Months: Exclusive focus on growth-related research.
• Early Game Skip: Avoid military research in the early stages; concentrate on construction and research speeds.
• Post-Growth Max: Rapid troop advancement followed, completing in just two months.
• Outcome: A slower initial pace, but eventually outpaces players who spread resources too thinly.

Speed Boost Targets

Aim for a 200% total boost through:

• Villa Upgrades: For construction speed.
• Bookstore Upgrades: For research speed.
• Sophia (3-star): Construction bonus.
• Amelia: Research bonus.
• Refugees: Butlers (construction) and Scientists (research).
• Shelter Research: Completing the growth technology tree.

Maximizing Value Through Timing

Timing significantly impacts the value of purchases. An accelerator used on the correct Alliance Skirmish day yields more value than one used merely to finish a timer prematurely.

Check the Calendar Before Buying

Items gain considerable value when synchronized with active events:

• Golden Wrenches: Best used during Vehicle Boost events.
• Accelerators: Utilize during Alliance Skirmish days.
• Wrenches/Accelerators: Score points in the Full Preparedness event.
• Power Cores: Acquire from the Merit Shop only during SVS.

Alliance Skirmish Synchronization

Save resources for the designated days:

• Monday: Golden Wrenches, blueprints.
• Tuesday: Construction accelerators.
• Wednesday: Research accelerators, badges.
• Thursday: Hero fragments, power cores.
• Friday: Training accelerators.
• Saturday: Combat—troop usage, attack events.

Quick Tips

• 2,000 Diamonds by Friday: Shield funds are non-negotiable.
• Avoid Direct Accelerators: This is the worst trade available.
• Prioritize Refugees: Butlers and Scientists are paramount for growth.
• Guard Your Shield Reserve: Never deplete it for minor purchases.
• Growth Research First: Patience in growth research pays off immensely.
• Lucky Dealer for Accelerators: Wait for 40%+ discounts.
• Use All Furylord Attacks: Gain free fuel and achievements.
• Claim 300 Free Fuel Daily: 100 from Katrina, plus 100 at 08:00 and 100 at 20:00. Follow the daily fuel schedule for optimal collection.
• Review Event Calendar: Align purchases with ongoing events.
• Weekly Golden Wrenches: Obtain 10 from VIP and 5 from Glory shops every week.
• VIP 10 Target: This unlocks Versatile Orange Fragments, a key resource.
