Last War: Upgrades and Buildings You Can Safely Postpone

To advance quickly in Last War, postpone internal resource production plots, wall fortifications beyond mandatory prerequisites, low-tier economic tech nodes, and secondary barracks. Progress in the early and mid-game relies on clearing Headquarters (HQ) milestones, expanding march sizes, and unlocking higher soldier tiers.

Internal base resource fields produce negligible hourly output compared to active world map gathering, event chests, and alliance rewards. Deferring low-impact projects preserves your limited builder queues, construction speedups, gold, and iron for structures that directly advance your base tier and squad power.

Low-Impact Buildings to Defer

Focus builder time exclusively on functional unlocks and the direct prerequisites required for your next Headquarters tier.

Passive Resource Production Fields

Upgrading Farmland, Iron Mines, and Gold plots yields minimal returns relative to their construction time and upfront costs. A high-tier resource field generates an amount of iron or food in an hour that active gathering marches or daily Arms Race crates match in minutes. Additionally, uncollected or stored internal resources make your base an attractive target during Warzone Duel and Kill Events. Keep resource plots at low levels until a future HQ requirement forces an upgrade.

Base Wall Beyond Prerequisites

Upgrading the Wall increases durability hit points, but wall durability alone cannot stop incoming attacks. If your garrison squad is defeated, a high-durability wall merely extends the time your base burns before it is forcibly relocated. Wall upgrades demand massive amounts of iron and gold that are better directed into military tech and unit promotions. Level your Wall only when it is an explicit requirement for your next HQ tier.

Secondary Barracks and Over-Expanded Hospitals

You only need a single Barracks leveled to your current HQ tier to unlock and train your highest-tier soldiers (such as T8, T9, or T10). Additional barracks can lag several levels behind without hurting your frontline combat strength; use lower-tier barracks to produce lower-tier units for batch promotions or to meet daily event training tasks. Similarly, keep Hospital upgrades capped to what protects your primary march during standard daily farming. Excess hospital beds lock up builder queues without providing economic acceleration.

Low-Priority Tech Center Nodes

Tech Center research queues are a major progression bottleneck. Defer branches in the Economy and Base Development trees that solely boost internal gathering speeds or passive crop, gold, and iron output.

• Defer passive production tech: Fractional percentage boosts to base generation yield far less value than the days of research time they consume.
• Skip deep gathering trees early: Unless an economy node is a strict prerequisite for an advanced military tier, leave it at level one.
• Focus on combat and scoring: Dedicate the Tech Center to troop damage mitigation, march capacity, unit lethality, and Alliance Duel scoring bonuses. Higher Alliance Duel reward chests return significantly more speedups and resource crates than economic tech nodes provide.

Optimal Builder Queue Strategy

Direct all builder allocations toward two goals: meeting the next HQ requirements and expanding primary march combat capacity.

1. Dedicate Builder One to HQ Requirements: Keep your primary builder continuously cycling between the Headquarters and its direct prerequisites, such as the Tech Center, Wall, or Tank Center.
2. Assign Builder Two to Functional Military Assets: Upgrade the Drill Grounds to expand troop march limits, the Alliance Center to reduce construction timers via alliance helps, and your primary Barracks.
3. Ignore Non-Essential Infrastructure: Leave auxiliary facilities, decorative elements, and passive production plots idle until your main combat and base tier milestones are secure.
