Last War Tech Research Priorities for Combat Power

To maximize effective squad power in Last War, prioritize upgrades in the Military research branch over general base and resource nodes. Focus your initial investments on primary combat stats—Attack, HP, and Defense—for the specific hero unit types actively deployed in your main squad.

Research Branch Priorities

Spreading research thin across every node inflates account level without improving combat performance. Focus resources where they directly improve battle results:

Research Branch	Priority Level	Key Focus Areas	Strategic Objective
Military	High	Squad Attack, Troop HP, Defense, Unit-Specific Tech	Directly increases hero damage output and combat survivability.
Development	Medium	Research Speed nodes	Reduces upgrade completion times across all branches.
Resource	Low	Minimum required for prerequisite unlocks	Avoid over-investing; resource nodes provide zero direct combat power.

Specialized Unit Nodes

Align specialized branch upgrades with your main squad composition:

Tank Squad Focus: Prioritize Tank-type damage and health nodes if your primary squad relies on Tank heroes.
Unused Squad Types: Skip Aircraft or Missile research nodes until you actively field dedicated squads for those unit types.
Stat Priority Order: Focus on Squad Attack first to increase damage output, followed by Troop HP and Defense to sustain frontline heroes in extended fights.

Managing Time and Resource Bottlenecks

As research levels scale, single upgrades require multiple days and high amounts of gold. Manage these limitations with the following steps:

Invest in Research Speed Early: Prioritize the Research Speed nodes within the Development tree to reduce completion times for high-tier Military nodes.
Conserve Gold Reserves: High-level research creates a heavy gold bottleneck. Stop non-essential utility upgrades whenever gold is needed for hero upgrades or main squad gear.
Time Completes with Events: Schedule long research projects to finish during Alliance Tech events to earn supplemental rewards and speedups.
Target Depth Over Breadth: Upgrade deep into specific high-tier combat nodes rather than unlocking numerous shallow, low-level technologies across unused categories.
