To unlock T10 troops efficiently in Last Z: Survival Shooter, focus your laboratory research primarily on the Combat and Development branches while stacking active speed buffs before initiating major upgrades. Reaching T10 requires heavy resource investments and long timers, making research management essential to prevent base progression bottlenecks.

Prioritizing Tech Trees and Requirements

Advancing to T10 troops requires direct focus on prerequisite tech trees rather than spreading laboratory time across all available research.

  • Target Core Branches: Prioritize projects in the Combat and Development tabs. Combat research provides necessary troop stats and tier requirements, while Development upgrades boost research speed and gathering efficiency to sustain late-game demands.
  • Verify Prerequisites: Inspect the Research Center requirements early to identify required secondary research nodes. Unlocking direct T10 paths often requires completing secondary branches off the main tech line.
  • Stack Pre-Research Buffs: Ensure alliance research speed tech and research-focused hero skills are fully activated before committing to long-duration research tasks. Speed buffs apply their reduction when the timer begins.

Resource Allocation and Speed-Up Strategy

T10 research demands large quantities of resources and extended project times. Structuring how you consume speed-ups and materials prevents economic stalls.

  1. Reserve Generic Speed-Ups: Hold generic speed-ups for the final, longest research projects in the T10 tree. Save shorter tasks for natural timers or specific research-only speed-ups.
  2. Time Completion with Events: Align the completion of long research projects with active power-up or research efficiency events to claim bonus rewards for subsequent projects.
  3. Preserve Resource Crates: Keep resource crates in your inventory to cover immediate research spikes instead of opening them for daily base upkeep.
  4. Gather Specialized Materials: Send idle marches to high-tier specialized resource tiles with fully optimized march capacities and gathering speed buffs active.
  5. Utilize Alliance Aid: Request alliance help immediately upon starting any research task to shave off initial timer percentages before using speed-up items.

Balancing Research Costs with Base Security

Focusing entirely on long-term tech development can leave your base under-defended during multi-day research timers. Adjust your research pace according to your server's current conflict level:

  • Peace Phase: If your server or region is in a stable diplomatic state, allocate the majority of your resource output and speed-ups toward accelerating the T10 tech queue. Keep your lab working continuously while running heroes through passive power development and equipment refinement.
  • War Phase: If active combat or raids are frequent, maintain a reserve of resources and speed-ups to replace lost frontline units and repair damaged structures. Avoid draining your entire resource pool into a single long-term research project if it leaves your base unable to defend against enemy attacks.
