Science Center

All research is done in the Science Center (SC). It is important to have something researching continuously. You can set researches while the Science Center is upgrading, you just have to click the building until the window opens. Alternatively, you can click the research button on the top right side of the screen to show what you are currently researching, and click "Research".

The researches affecting resource production include Agriculture, Woodcraft, Masonry, Alloys, and Energy Collection.

The researches affecting troops /dragon performance include Rapid Deployment, Weapons Calibration, Metallurgy, Medicine, Dragonry, and Aerial Combat (Great/Elemental ONLY).

Suggested Sequence of Researches

This is only for the first few levels until you get the hang of the buildings associated with the researches. This is also assuming you are collecting resources from Camps which are good sources of Food and Wood early on and have 3 of each field producing Stone and Ore. Then when you are able, attacking other players for resources. The Buildings needed for each research are included in the table to provide a reference of priorities while upgrading buildings and researches.

This should be adapted to fit your needs at that time in the game, there is no such thing as the absolute walkthrough for researches due to lack of resources mainly as well as other factors such as time. Long research times should be while you are offline, while short are for when you are online.

Building Times are according to City times which vary depending on level of Levitation.

This has been confirmed. Towards the end, the researches and buildings can be switched around a lot depending on what you want to get done, so I just included the buildings and the researches to get all of the troops started. For the Full Building Sequence click the link.
