If your growth in Last Asylum: Plague feels slow, the problem usually isn’t your heroes or troops—it’s your Research Lab. This building quietly controls your entire account progression, and the way you prioritize it determines whether you scale efficiently or fall behind. So instead of asking what should I upgrade next, the better question is: what should I research first and why?
Why the Research Lab Is So Important
The Research Lab isn’t just another upgrade building—it’s a multiplier system that affects every part of your gameplay loop.
Every key system is tied to research in some way:
- Faster building speeds
- Shorter research times
- Higher resource income
- Stronger troops and heroes
What makes it even more critical is that research compounds over time. A small early boost like increased research speed doesn’t just save time once—it accelerates every future upgrade you’ll ever do. That’s why experienced players treat the Research Lab as a long-term investment engine, not a short-term power boost.
Core Mechanics You Shouldn’t Ignore
One of the most impactful upgrades is unlocking the second research queue. Being able to run two researches at the same time dramatically increases your overall progression speed, and over longer periods the gap becomes extremely noticeable. For active players, this is one of the highest-value upgrades you can invest in.
Another key point is that research order matters far more than simply pushing levels. Speed-related upgrades such as research speed and construction speed should always come first because they affect everything that follows. If you delay these, every future upgrade becomes slower, which creates a long-term disadvantage that is difficult to recover from.
Another layer that many players overlook is research planning over time. Instead of deciding upgrades one by one, it’s more efficient to plan your research in blocks. For example, grouping together speed-related upgrades first, followed by economy expansion, ensures that each phase of your progression supports the next. This kind of structured planning reduces downtime and prevents situations where you lack either resources or time efficiency. Over the long run, a planned research path will always outperform reactive upgrading.
Research Priority Guide
①Development Tech
This should always be your starting point. Focus on improving construction speed, research speed, and unlocking essential buildings. These upgrades act as the foundation of your account’s growth. The earlier you invest in them, the more value they generate over time because every system benefits from faster progression.
At this stage, managing your speedups efficiently becomes just as important as choosing the right research. Short timers should usually be completed naturally, while longer research projects are better paired with speedups during events or progression spikes. This ensures that you maximize the value of every resource spent while maintaining a steady upgrade flow.
②Economy Tech
Once your development speed is optimized, resources become the next bottleneck. At this stage, the focus should shift toward expanding resource generation capacity and improving gathering efficiency. Increasing the number of resource sources is often more impactful than simply boosting production percentages, as it ensures a stable supply for continuous upgrades.
A common issue during this phase is hitting resource bottlenecks even when production seems sufficient. This usually happens because upgrade costs scale faster than passive income. To solve this, players should combine passive production with active gathering and event rewards, creating a more balanced resource flow that can sustain continuous development.
③Hero and Troop Tech
After stabilizing your economy, combat scaling becomes the priority. Instead of spreading resources across multiple paths, it is far more efficient to focus on a single hero class that matches your main team. From there, increasing troop capacity provides the best overall value before transitioning into offensive stats. This approach ensures consistent and efficient power growth.
It’s also worth noting that your research focus may slightly shift depending on whether you prioritize PvE or PvP. PvE progression benefits more from stable scaling and efficiency, while PvP places greater emphasis on burst power and optimized troop composition. Understanding your main focus helps you allocate research points more effectively instead of following a one-size-fits-all approach.
④Alliance Duel Tech
This branch is mainly about improving event rewards rather than direct combat strength. You don’t need to fully invest in it early, but unlocking key reward tiers significantly improves your long-term gains. Planning ahead for this ensures you don’t miss out on valuable progression opportunities during events.
⑤Elite Troop Tech
As you approach the late game, unlocking higher-tier troops becomes essential. This is a progression requirement rather than an optional upgrade. Delaying it too long can slow your advancement in both PvE and PvP, so it should be prepared for in advance rather than rushed later.
Common Research Mistakes to Avoid
Many players slow their progress by making avoidable mistakes. Following quest prompts without considering efficiency often leads to suboptimal upgrades. Spreading investments evenly across all tech trees prevents any single area from becoming strong enough to make an impact. Ignoring early research speed upgrades results in long-term delays, and failing to prepare for event-related research can reduce overall rewards. Avoiding these issues will significantly improve your progression pace.
Advanced Tip: Think in Terms of Account Value
Instead of focusing only on immediate power increases, it’s more effective to think in terms of long-term account value. Every research decision should contribute to sustained growth rather than short-term gains. This mindset helps you build momentum that compounds over time and keeps your progression efficient.
As your account progresses, the value of each percentage-based upgrade increases significantly due to scaling costs and longer timers. This means early investments in speed and efficiency become even more impactful later on. Players who prioritize these early will notice a widening gap over time compared to those who focus only on immediate power gains.
Conclusion
Prioritize development, stabilize your economy, and then focus on combat. That’s the structure that keeps your progression efficient. If you want to accelerate your growth, using LDShop to top up Last Asylum can help you unlock key upgrades faster and stay ahead with less grind.
