Last Z: Survival Shooter: How to Get 350 Golden Wrenches a Month

To collect roughly 350 Golden Wrenches each month in Last Z: Survival Shooter without spending real money, focus on clearing weekly Alliance Duel chests, buying discounted inventory from the Diamond store, and hitting intermediate thresholds in recurring mini-events.

Following this routine generates 70 to 100 Golden Wrenches per week, yielding an average of 350 wrenches across a four-week cycle.

Source / Activity	Weekly Yield	Monthly Yield (4 Weeks)
Alliance Duel Milestones	35–45	140–180
Weekly Diamond Shop Discounts	15–25	60–100
Rotating Mini-Events	15–20	60–80
Daily Quests & Radar Tasks	5–10	20–40
Total Target	70–100	280–400 (Avg. ~350)

Clear All Nine Alliance Duel Chests Weekly

The Alliance Duel cycle serves as your primary baseline for Golden Wrenches, contributing nearly half of your monthly total. Reaching the highest-tier chests requires hitting daily point targets across specific competition themes, such as tech upgrades, unit training, or radar exploration.

Pace resource spending: Spend speedups, recruitment tickets, and stamina cans only up to the score threshold required to unlock the final daily duel chest.
Hoard between cycles: Save surplus progression items for their designated duel days so you never miss end-of-week reward chests containing bulk wrench allocations.

Buy Discounted Stock from the Diamond Shop

Do not purchase Golden Wrenches at standard retail pricing. Instead, check the VIP and Diamond stores each Monday following the weekly reset to purchase discounted wrench stock.

Keep a currency reserve: Maintain a working balance of 5,000 to 10,000 Diamonds to immediately buy out the discounted bundles upon reset.
Convert event tokens: If a seasonal market or trade festival appears, prioritize converting surplus exchange tokens into Golden Wrenches before purchasing cosmetic items or standard materials.

Hit Milestones in Mini-Events and Radar Tasks

Rotating events such as Arms Race, vehicle training days, and weekend trials offer Golden Wrenches as intermediate rewards. You do not need to rank at the top of cross-server leaderboards to benefit. Reaching phase three or phase four reward tiers consistently delivers 15 to 20 wrenches each week.

For passive income, clear your radar station down to zero missions twice per day. Elite zombie encounters and rescue tasks on high-level radar missions can award an extra 5 to 10 wrenches weekly without spending Diamonds.

Hoard Wrenches for Spending Rebates

Do not consume Golden Wrenches immediately upon acquiring them. Hold your wrenches in inventory until a vehicle modification contest or spending event becomes active.

Target bulk milestones: Save wrenches until you can spend them in designated brackets (such as 100, 200, or 400) during active score-up windows.
Collect rebate chests: Spending during these events awards milestone chests that refund a portion of your consumed wrenches and provide vehicle modification parts.
Upgrade primary components first: Invest your accumulated wrenches into the front armor and main cannon of your primary combat squad's vehicle to maximize march capacity and damage before upgrading secondary utility vehicles.
