In Rise of Kingdoms (ROK), the title of scientist is a temporary title that can be held by a player for a limited period of time. The duration of the scientist title varies depending on the level of the Technology Research Facility and the number of technology points invested in it.
To unlock the scientist title, players need to upgrade their Technology Research Facility and accumulate a certain number of technology points. Once achieved, players can activate the title and enjoy its benefits.
The duration of the scientist title ranges from a few hours to several days, depending on the level of the Technology Research Facility. At lower levels, the title may last for a shorter duration, whereas at higher levels, players can enjoy an extended period as a scientist.
It is worth noting that the scientist title provides various benefits to the player. It increases the speed of technology research, allowing for quicker advancements in various fields. This can be advantageous for players who prioritize technological growth and progress.
