Last War Mastery Research Tech Priorities for Squad Power

To maximize your combat strength in Last War, focus your Mastery Research tree entirely on your primary squad composition using a specialized "tall" upgrade path. Invest your research resources into Attack nodes first, followed by HP nodes, and restrict stat upgrades to your main squad's hero unit type—such as Tank, Air, or Missile—before considering secondary squads or utility research.

Mastery Research Upgrade Priorities

Mastery Research grants permanent, percentage-based stat increases that apply to every hero in your squad. Unlike flat hero level gains, percentage buffs scale higher as your underlying hero stats increase, keeping your squad competitive across long-term PvP and Alliance events.

To spend research materials efficiently, follow this progression order:

1. Squad Hero Type Buffs: Direct high-tier research toward the specific hero classification running in your main line (for example, Tank-specific trees if your primary squad is Tank-heavy).
2. Attack Nodes: Prioritize offensive damage nodes to ensure your squad can reliably penetrate rival hero defenses.
3. HP Nodes: Prioritize HP over Defense within survivability branches. Extra HP provides a larger damage buffer during long fights than raw defense values.
4. Defense Nodes: Upgrade Defense after maxing out available Attack and HP options in your main branch.
5. Utility and Secondary Trees: Upgrade general base utility or secondary troop trees only when low-cost prerequisites are required or during quiet periods with excess materials.

Resource Management and Event Timing

Effective tech progression relies on concentrating spending rather than spreading research points evenly across all trees. A wide approach leaves individual stats underpowered, whereas pushing a single tree as far as possible yields high immediate combat performance.

• Avoid Stat Inflation: Building total account power through extra structures or low-level hero upgrades creates a high power number without battle strength. Optimized Mastery Research ensures a lower-power account can defeat unoptimized opponents with higher base numbers.
• Save Speed-ups for Power Growth Events: Hold major tech pushes and research speed-ups for recurring game events that grant rewards for research power increases. Cycling event milestone rewards back into tech speeds up overall progression.
• Maintain Tech Assets Across Meta Shifts: Hero choices may change as new units release, but core type-specific research remains intact on your account. Keeping research concentrated on key troop types minimizes stat loss if you replace individual heroes within that unit type later.
