Last Z: Survival Shooter Post-SvS Research Guide

After a Server vs. Server (SvS) event in Last Z: Survival Shooter, check your battle logs to identify unit vulnerabilities before committing resources to new Research Center projects. Prioritize percentage-based combat nodes that boost the damage and survivability of your primary troop type, then schedule upgrades around your available speed-ups and building prerequisites.

Post-SvS Research Priorities

Focusing your Research Center on combat stat nodes immediately after SvS yields the highest return on technical investment.

• Target Main Troop Types: Concentrate research on branches dedicated to your primary damage-dealing units rather than spreading resources evenly across all categories.
• Prioritize Combat Stats: Select nodes that provide percentage-based attack, defense, and health bonuses to enhance army survival during high-intensity battles.
• Time Upgrades After Events: Initiate major technical projects right after inter-server conflict concludes, when battle performance reveals clear defensive or offensive gaps.

Resource Management and Base Constraints

Advanced tech nodes require substantial stockpiles of raw materials and acceleration items. Over-committing to research can bottleneck other base operations if reserves run dry.

• Pace Accelerator Use: Reserve research speed-ups for final node tiers, where completion times increase significantly.
• Maintain Resource Reserves: Avoid exhausting material reserves required for immediate troop training or emergency hospital healing.
• Unlock Time-Reduction Nodes: Invest early in nodes that reduce subsequent research times to build a compounding speed advantage.
• Check Prerequisites: Ensure your Headquarters level and base infrastructure meet requirements for advanced nodes before committing stockpiles.
• Coordinate with Hero Growth: Use research stat bonuses to complement fully leveled heroes and optimized gear rather than relying on technical nodes to replace character growth.

Post-SvS Research Action Plan

1. Review SvS battle logs to determine whether offensive output, unit defense, or troop health requires immediate improvement.
2. Confirm your Headquarters level satisfies prerequisites for target tech nodes.
3. Queue combat stat nodes dedicated to your primary troop type in the Research Center.
4. Save adequate material reserves for troop maintenance and emergency hospital healing before applying research speed-ups.
