Stronghold Kingdoms Research Technology Tree Manual Guide
Research can be confusing and complicated in Stronghold Kingdom if you do not know the type of research that you are going for in game. This guide or research tree manual will detail out the different possible researching paths that you can take to advance further in game. You can use the search function to quickly narrow down the type of research that you need to unlock certain buildings. However, the research cost and time is not included because there are other factors that can alter and decrease the time and cost needed for individual research. If you have found this guide useful, please share them with your team mates and friends. Good luck in game. Please also check out my list of Stronghold Kingdom guides for more helpful tips.
This table will help you to decide how to learn various research, and how to get gold effectively via Stronghold Kingdoms researches.
Alternatively, it is recommended that you use this alongside with the Stronghold Honor and Ranks List as well as the Village Listing to know the overall requirements of the various buildings in game.
