Last Z: Survival Shooter Thursday Alliance Duel Event Guide

To maximize event points as a free-to-play player in Last Z: Survival Shooter, save all hero upgrades, recruitment tickets, and promotion materials until Thursday. Thursday features the Hero Development theme in both Alliance Duel and Total War Preparation. Aligning your hero upgrades with active Arms Race stages allows you to complete multiple milestone reward tracks simultaneously without spending extra resources.

Stockpile Hero Resources During the Week

Alliance Duel rewards burst resource consumption. Upgrading heroes between Friday and Wednesday wastes scoring potential because those actions yield zero event points outside the Hero Development cycle. Keep the following items in your inventory until the Thursday server reset:

• Recruitment Orders: Save standard and advanced recruitment tickets to complete pull-based scoring tasks.
• Hero EXP Vials: Hold all level-up experience rather than raising the levels of newly acquired heroes immediately.
• Hero Shards and Selection Chests: Keep duplicate hero fragments and unopened shard boxes in your backpack, postponing star promotions until the event is live.
• Skill Badges and Combat Manuals: Retain all skill materials to unlock ability tiers during matching event phases.

Time Upgrades With Arms Race Stages

Do not spend your stockpiled inventory immediately when Thursday begins. While Alliance Duel runs across the entire 24-hour cycle, Arms Race objectives rotate in shorter intervals throughout the day.

Wait until the active Arms Race window matches your target activity before using resources:

Timing your spending to match an active hero-focused Arms Race window lets single upgrade actions clear milestones in Alliance Duel, Total War Preparation, and Arms Race simultaneously.

Efficient Spending Order and Chest Caps

To maximize point yields from limited free-to-play materials, follow an efficient sequence and stop as soon as individual milestones are met:

1. Target low-level units first: Leveling secondary or SR (purple) heroes from level 1 up to level 30 or 40 requires minimal EXP vials while generating standard per-level event points. This yields a higher point-to-EXP ratio than pumping high-tier heroes past level 90.
2. Execute star promotions: Activate all pending star promotions to trigger large point bursts toward higher chest tiers.
3. Upgrade key skills: Invest skill badges into your primary frontline and damage units to hit remaining point requirements.
4. Halt at chest nine: Stop spending immediately once you claim the ninth and final individual Alliance Duel chest and the top active Arms Race chest.

Points earned beyond the ninth individual chest only advance competitive rank leaderboards against paying players. Saving any leftover recruitment tickets, EXP, and shards ensures you have enough resources to clear the ninth chest again the following Thursday.
