Last War Research Guide: Tech Center Setup and Branch Priorities

To cut down long research timers and prevent account progression bottlenecks in Last War, assign your highest-rarity survivors directly to the Tech Center and unlock foundational development nodes before investing deeply into military trees.

Optimizing Tech Center Survivor Assignments

Long research timers are the primary bottleneck in late-game progression, scaling from a few hours early on to multiple weeks per node. Spreading production survivors evenly across resource buildings yields minor raw output at the expense of research momentum. Stacking your best survivors in the Tech Center applies percentage-based time reductions across every active research project.

Follow these steps to reallocate your survivor roster:

Review your survivor roster: Open your survivor inventory and locate high-rarity (UR and SSR) production survivors with research-speed perks.
Reassign high-tier survivors: Remove top-level and high-star survivors from secondary resource buildings, such as farms or smelters, and place them into your Tech Center slots.
Concentrate time-reduction perks: Keep your strongest research-focused survivors dedicated to the Tech Center. A percentage reduction on a multi-day project saves days of speed-ups, which outweighs modest gains in iron or food production.

Tech Branch Priorities

Rushing deep into expensive combat branches early stalls your account by consuming gold needed for basic upgrades. Build economic efficiency and event reward scaling first, then upgrade military branches that serve your primary squad.

Branch Category	Key Focus Nodes	Account Benefit	Priority Level
Development / Economy	Construction Speed, Tech Speed, Resource Yields	Permanently reduces timers across the base	High (Immediate)
Alliance / VS Trees	Duel Rewards, Chest Points, Help Speed	Yields extra speed-ups, gold, and Valor Badges from chests	High (Core Progression)
Squad / Military	March Size, Troop HP, Attack, Defense	Directly powers up your primary march for PvE and PvP	Medium (Iterative)
Specialized Troop Types	Tank, Aircraft, and Missile Buffs	Strengthens specific unit types after the main squad is set	Situational (Mid to Late Game)

Begin by unlocking nodes in the Development tree that provide permanent percentage boosts to construction and research speed. Each completed speed node reduces the time required for every future upgrade.

Next, advance through Alliance VS research nodes. Unlocking higher-tier Alliance Duel chests generates an ongoing supply of Valor Badges, gold, and tech speed-ups, creating a self-sustaining cycle to fund higher-tier projects.

Project Timing and Avoiding Common Traps

Maximizing your research value requires strategic timing and disciplined node selection:

Lock in buffs before starting: Research duration is calculated at the exact moment a project begins. Request temporary Ministry titles or alliance territory buffs before initiating high-cost nodes. If the buff expires while research is underway, the reduced timer remains locked in.
Sync completions with server events: Schedule lengthy or high-point tech completions to finish during Alliance VS Research Day or matching Arms Race stages. This secures milestone chests without requiring excessive speed-up items.
Focus on one troop discipline: Avoid spreading military research evenly across Tanks, Aircraft, and Missiles. Identify your primary march composition and invest exclusively in that unit type. Splitting combat tech across all three disciplines dilutes squad effectiveness and exhausts gold reserves needed for higher Soldier tier unlocks.
