Last Z: Survival Shooter Post-T10 Progression Guide

After unlocking T10 research in Last Z: Survival Shooter, your main progression changes from rushing higher troop tiers to refining overall army stats. Completing T10 research marks the transition into late-game optimization, where combat strength depends heavily on hero attributes, equipment quality, and sustainable resource management.

To maintain progression after T10, reallocate your daily speed-ups and resources toward four key areas: hero development, gear refinement, chief equipment, and passive resource production.

Upgrading Heroes and Skill Synergies

Once T10 troops are active, heroes become the main driver of additional battle power. Instead of spending resources purely on mass troop training, prioritize building a specialized hero roster that directly supports your primary unit type.

Farm Hero Shards: Focus on gathering shards for high-tier heroes to unlock key stat multipliers.
Enhance Active Skills: Upgrade skills that boost the attack, defense, or health of your primary troop types.
Check Squad Synergies: Open the combat menu regularly to ensure your active march formations match the bonuses provided by your active research paths.

When research speed progression slows down, gear refinement offers an effective way to boost army attributes. Focus daily resource gathering on collecting materials for gear upgrades across your equipment slots.

Spread refinement levels evenly across your active gear sets rather than putting all resources into a single item, as high-level single-item upgrades suffer from diminishing returns.

Gear Category	Key Benefit	Practical Application
Uniform Refinement	Increases base defense and health	Helps units survive longer during extended rally combat.
Weapon Upgrades	Boosts direct attack power	Improves overall damage output and kill ratio in PvP encounters.
Accessory Calibration	Grants situational stat buffs	Provides tactical advantages during event battles and capital fights.

Enhancing Chief Equipment

Chief equipment provides permanent, passive percentage bonuses to attack and defense that apply to all deployed units regardless of troop tier. Because these stats are non-expendable, chief gear is one of the safest long-term investments after finishing major research milestones.

When upgrading chief equipment, monitor your material stockpiles and hold valuable components for major tier jumps rather than spending them immediately on minor incremental increases. Focus first on pieces that provide direct percentage boosts to offensive and defensive unit stats.

Strategic Resource and Base Management

With the initial resource burden of T10 research finished, pivot your base planning toward resource preservation and automated income.

Maintain a Battle Reserve: Keep a dedicated stock of resources on hand to heal T10 casualties quickly during server events.
Redirect Speed-ups: Shift speed-up usage from long-term research projects toward troop recovery and event participation.
Optimize Base Production: Invest remaining research capacity into resource output and storage capacity. Maximizing passive income guarantees a continuous flow of materials for ongoing gear and chief equipment upgrades.
