To increase your Combat Power quickly in Last Z: Survival Shooter, concentrate your resources on your top three primary march heroes, reserve gear refinement materials for high-tier equipment, and maintain constant research in the Laboratory's combat development branch. Spreading resources across your entire roster slows progression; focusing on your main formation delivers immediate, permanent stat gains.

Upgrade Primary Heroes and Skills
Hero upgrades provide the fastest increase to base Combat Power. Rather than spreading experience materials and skill books evenly across all unlocked heroes, funnel them exclusively into the three units forming your main battle march.
- Hero Level Caps: Push your top three heroes to the maximum level permitted by your current Headquarters level.
- Skill Tier Priority: Use skill books to upgrade hero skills. Higher skill levels grant percentage-based stat multipliers to deployed troops.
- Skill Book Acquisition: Complete daily events that offer skill books as top-tier rewards to maintain steady skill development.

Equipment Refinement and Set Matching
Equipment acts as a force multiplier for hero stats. Avoid spending rare upgrade materials on low-tier gear that will soon be replaced.
| Gear Action | Target Equipment | Resource Rule | Impact |
|---|---|---|---|
| Forging | Higher-star items | Craft role-specific gear (Damage vs. Support) | Raises primary hero attributes |
| Refinement | Purple or Orange gear only | Save Refinement Stones for high-tier pieces | Adds secondary stats like Army Attack and Defense |

Laboratory Research Priorities
Research provides permanent, account-wide statistical bonuses that apply to all deployed armies. Keep your Laboratory active at all times.
- Focus the Combat Branch: Enter the combat development research tree first to unlock direct army buffs.
- Target Core Nodes: Prioritize Army Attack and Army Defense nodes before taking utility branches.
- Time Event Speed-Ups: Save speed-up items to use during dedicated research events, maximizing event rewards while completing tech upgrades.

Daily Resource Routine
To maintain continuous hero, gear, and research progress without bottlenecks, stick to a daily base management routine:
- Resource Gathering: Keep gathering marches permanently deployed to high-yield resource nodes outside your base.
- Silo Management: Empty passive resource collectors inside your shelter before production caps out.
- Daily Missions: Complete all daily task objectives to earn speed-ups, diamonds, and crafting materials needed for upgrade cycles.

I wish I had read this before upgrading the wrong thing.
Good guide for Last Z: Survival Shooter players. The heroes part was useful.
Can you add more details about heroes in a future update?
This helped me understand heroes much better.
