How to Unlock T5 Troops in Call of Dragons: The Ultimate Strategy Guide

Unlocking Tier 5 (T5) troops is the definitive endgame milestone in Call of Dragons. These elite units represent the pinnacle of military power, offering significantly higher stats and combat efficacy compared to their T4 counterparts. However, the path to T5 is a marathon, not a sprint. It requires years of accumulated research speedups and a highly optimized economy. This guide provides the expert roadmap to navigating the technical requirements, economic hurdles, and strategic trade-offs involved in reaching this prestigious tier.

The Technical Prerequisites for Tier 5

Before you can even consider the T5 research tree, you must satisfy rigorous infrastructure demands. The game locks the final military research tiers behind specific building levels, primarily tied to your City Hall progression.

City Hall Level 25: This is the non-negotiable gateway. You cannot unlock T5 units without a maxed-out City Hall.
Academy Level 25: Your Academy acts as the bottleneck for all military research. You must upgrade it to level 25 to access the final tiers of the military technology tree.
Military Infrastructure: You must upgrade your barracks, stables, archery ranges, and magic schools to level 25. These buildings are hard requirements to unlock the final nodes in the research tree.
The Research Tree: You must complete the entirety of the T4 research for a specific unit type, followed by the advanced military research nodes that serve as the "bridge" to T5. This includes investments in logistics, hospital capacity, and troop training speed.

The Art of Hoarding: Managing Speedups

The most common mistake players make is burning universal speedups on mid-game research. To reach T5 without stalling, you must adopt a disciplined "Hoarding Mentality."

Avoid "Convenience" Spending: Do not use universal speedups to finish minor upgrades or tech that doesn't directly contribute to your City Hall or Academy progression. Every speedup spent early is a day of T5 progress lost.
Event Synergy: Always save your major speedup pushes for high-value events like "Power Up" or "Research Speed" events. Using your hoard during these windows allows you to double-dip, gaining massive combat power while simultaneously earning legendary hero tokens, specialized materials, or alliance rewards.
Maximize Alliance Help: Never start a long-duration research project without first requesting alliance help. Each member who clicks "Help" reduces the time by 1% (up to a cap). Over the course of a multi-week research project, this can save you days—or even weeks—of speedups.

Balancing the Gold Economy

T5 research is notoriously gold-hungry. As you approach the final nodes, you will find that your bottleneck shifts from time to actual resource costs. If you lack the gold, you cannot initiate the research, regardless of how many speedups you have saved.

Prioritize Gold Tech: Within the Economic research tree, prioritize all nodes that increase gold production and gathering speed.
Hero Talents: Use secondary heroes with "Gathering" talent trees to strip-mine gold nodes on the map. During downtime, your legions should never be idle; they should be parked on high-yield gold deposits.
The "Speedup-to-Gold" Ratio: If you find yourself with an excess of speedups but no gold, pause your research. It is mathematically better to farm for two extra days than to waste speedups on a project that you cannot sustain.

The Hidden Cost: Sustainability and Healing

Unlocking T5 troops is only half the battle; maintaining them is the true test. T5 units carry a significantly higher gold and resource cost for both training and healing.

If you unlock T5 units before your economy is fully developed, you risk "bricking" your account. If you participate in a massive field battle and lose a large portion of your T5 legions, the healing costs could deplete your reserves entirely, preventing you from training new troops or completing future research.

Expert Tip: Only push for T5 if your daily resource production (from nodes, alliance territory, and building production) can comfortably cover the expected healing costs of a full-scale war.

Strategic Priority: Which Unit to Unlock First?

You should never attempt to unlock all four T5 unit types at once. The research cost is exponential, and spreading your resources thin will leave you with a weak, middle-of-the-road army.

Match Your Heroes: Identify your strongest hero pair. If you have maxed out an Infantry commander, prioritize T5 Infantry. The stat bonus from T5 units scales multiplicatively with the skill damage and passives of your legendary heroes.
Meta Considerations: Assess the current meta in your server. If your alliance needs more frontline tanks for KvK (Kingdom vs. Kingdom), prioritize Infantry. If you need more high-damage glass cannons for objective control, focus on Mages or Archers.
One Specialized Legion: Aim to create one "Elite" legion first. Having one unstoppable T5 legion is significantly more effective in combat than having four mediocre T4 legions that cannot trade efficiently with enemy whales.

Common Mistakes to Avoid

Ignoring Hospital Capacity: As you increase your troop power, ensure your hospital capacity grows with it. If your hospital fills up during combat, your wounded troops will die, representing a massive loss of resources and time.
Neglecting the "Free" Time: Always aim to have your research queue running 24/7. Use your speedups only at the end of a project to finish it instantly, allowing you to start the next one immediately. Never let the Academy sit idle while you sleep.
Over-investing in Buildings: While City Hall is essential, don't waste resources upgrading non-essential buildings (like decorative structures or lower-tier resource nodes) if it delays your Academy progression.

Final Verdict: The Path to Mastery

Reaching T5 in Call of Dragons is a test of patience and resource management. By focusing on your economy first, hoarding your speedups for major events, and specializing in one unit type that complements your primary heroes, you will eventually reach the power ceiling required to dominate the map. Remember: it is better to be a highly efficient T4 player with a massive resource stockpile than a struggling T5 player who cannot afford to field their own army. Focus on the long game, stay active in your alliance, and the T5 power spike will be yours.
