How to do I research Technology?
In order to research technologies, you will first need to construct a Alchemy Lab. Once construction is complete, you can see the list of available technologies by clicking on the Alchemy Lab. Prerequisites that have not been met will be listed in red. Once you have completed the prerequisites for a technology, you can begin researching it.
Technologies grant your Cities bonuses such as increased production of resources, increased troop health and attacks, or more information when scouting. They play a heavy role in combat as many of the technologies can boost your army's attacks, defenses and health.
Technology that is completed in one city will apply to all your other cities.
