To level up your Castle efficiently and unlock higher-tier troops (T4/T5) as fast as possible, follow this core rule: "Do not upgrade everything!"

🎯 Primary Focus: Focus only on the prerequisite buildings required for the Castle upgrade (such as the Wall and the specific secondary building shown in the requirements).

🌾 Storages & Academy: Keep your Storages leveled up so they can hold your resources, and prioritize Academy research to increase building and research speeds.

🛡️ Hospital Capacity: Don't neglect your Hospitals! Upgrade them so they can hold your troops in case of a sudden attack, preventing permanent troop loss.

💡 Pro Tip: Save your Building Speedups for major "Building Events" to maximize your rewards while rushing your Castle level!
