Last Z: Survival Shooter Diamond Spending Priority Guide

In Last Z: Survival Shooter, invest your Diamonds primarily into permanent VIP milestone progression, cheap daily Stamina refills, and heavily discounted consumables from the Mystery Merchant. You should also maintain a reserve of 3,000 to 5,000 Diamonds for emergency Peace Shields and teleports during cross-server combat. Avoid spending Diamonds directly on raw building timers or base resources like Food, Iron, and Oil.

Primary Spending Priorities

Diamonds offer the highest return when converted into permanent account buffs or leveraged through discounted rates. Distribute your currency across these core areas:

1. VIP Level Milestones

Purchasing VIP points with Diamonds provides lasting value by unlocking permanent speed and capacity boosts, along with recurring daily rewards.

• VIP 8: Grants construction queue acceleration and increased squad capacity. Free-to-play and low-spending players should push toward this threshold first.
• VIP 10: Unlocks guaranteed daily Orange (Legendary) Hero Fragments from the daily VIP chest, providing steady hero ascension without relying on paid bundles.
• Timing: When possible, allocate bulk Diamond amounts to VIP points during VS Alliance Duel spending events to earn progress toward event milestone chests simultaneously.

2. Daily Stamina Refills

Stamina converts directly into Commander EXP, radar event rewards, Alliance Doom rally loot, and crafting materials. Because the Diamond cost increases with each successive purchase each day, buy Stamina in controlled daily increments rather than bingeing during a single session.

Direct the extra Stamina toward high-level Doom rallies and daily radar tasks to farm vehicle parts, badges, and gear blueprints.

3. Mystery Merchant Discounts

The rotating Mystery Merchant (Black Market) offers consumables at 50% to 70% off standard store rates. Limit your purchases to high-value utility items:

• 8-Hour and 24-Hour Speedups: Buy when discounted at 60% or higher, then save them for acceleration-scoring days in events like Enemy Buster.
• Advanced Teleports: Keep two to three discounted teleports in your inventory for alliance warfare and emergency relocation.
• Recruitment Tickets: Purchase golden recruitment tickets only when offered at deep discounts, saving them for milestone recruitment events.

Defensive Emergency Reserve

Always maintain a baseline balance of 3,000 to 5,000 Diamonds specifically for defense during State vs. State (SvS) or Enemy Buster phases:

• Peace Shields: Maintain active 8-hour or 24-hour shields if your base is exposed during combat phases. Buying a shield with Diamonds is significantly cheaper than replacing or healing high-tier troops.
• Emergency Relocators: Use an immediate teleport purchase if your base comes under focused rally fire and inventory teleports are unavailable.
• Hospital Healing: In high-stakes alliance defenses, use Diamonds on hospital healing speedups to restore defenders without draining alliance reinforcers.

Where Not to Spend Diamonds

To prevent stalling your mid-game growth, avoid these low-value currency sinks:

• Instant Timer Finishes: Do not click the Diamond prompt to immediately complete a building, research node, or training queue. Instead, combine alliance helps with discounted inventory speedups.
• Standard Store Resources: Never purchase basic resources (Food, Iron, Oil) with Diamonds. Rely on world-map gathering tiles, zombie hunting, and event reward crates to cover resource deficits.
• Full-Price Hero Recruitment: Avoid spending full-price Diamonds on standard recruitment pulls outside of dedicated rebate or spend-and-claim event windows.
