In Last Z: Survival Shooter, select the 800 Golden Wrenches if your vehicle parts and garage nodes are still progressing. Take the Halloween HQ Aura only if your main combat vehicles are already maxed out and your account relies on global percentage multipliers to gain combat power.
The Halloween Havoc event places both rewards in the same milestone tier, meaning claiming one locks you out of the other for the rest of the event cycle.

Why 800 Golden Wrenches Benefit Most Players
Vehicle modification is one of the tightest progression bottlenecks in Last Z: Survival Shooter. Golden Wrenches are required to upgrade high-tier vehicle parts, calibrate combat stats, and unlock key nodes in the vehicle garage.
Claiming a lump sum of 800 wrenches provides immediate battlefield advantages:
- Expanded March Size: Upgrading specific vehicle nodes increases your squad's troop capacity, which directly improves duel outcomes.
- Higher Combat Attributes: Vehicle parts grant direct boosts to Lethality and Armor, solving mechanical deficits in State vs. State battles.
- Time Savings: Securing 800 wrenches at once bypasses weeks of slow accumulation through weekly alliance milestones and standard shop resets.
If your primary combat formation consistently struggles due to lower troop capacity or underleveled vehicle components, cosmetic bonuses cannot compensate for the missing base stats.

When to Pick the Halloween HQ Aura
The Halloween HQ Aura provides permanent, passive percentage increases to squad stats such as attack, defense, or troop HP. These bonuses remain active across all deployed formations even if you change your visible base skin later.
However, percentage multipliers scale entirely from your account's existing base values. A 2% to 5% stat increase yields minor gains if your core hero gear, research, and vehicle parts are underdeveloped.
The HQ Aura is the better choice only under specific conditions:
- Your primary and secondary combat vehicles are already fully upgraded or close to node caps.
- Your account has reached the point where raw upgrade materials offer diminishing returns.
- You prioritize collecting limited-time event cosmetics that rarely return outside seasonal reruns.

Quick Decision Checklist
Before the Halloween Havoc event store closes, review your vehicle garage and choose based on your current account stage:
- Pick the 800 Golden Wrenches if:
- Your main vehicle has empty or low-tier mod slots.
- Your march capacity is lower than average for your bracket.
- You are a free-to-play or budget player needing functional combat power.
- Pick the Halloween HQ Aura if:
- Your vehicle garage nodes and calibrations are already completed.
- You already have high base stats to multiply with global percentage buffs.
- You want an exclusive visual asset that cannot be farmed through standard progression.
