R&D (Research and Development) is where you upgrade your military strength and customize your gameplay in Battlecry.
In this section, you can spend Skill Points and Tactical Points to improve different aspects of your army. You can also adjust your strategy and update your flag.
R&D plays a major role in shaping how your military performs in battles. Whether you want more health, stronger attacks, or better resource generation, this is where you make those improvements.
Using R&D effectively can give you a strong advantage over other players.
