"Tower, before we get into the rewards, can you tell me more about the towers? I seem to have noticed that some were giving me classes and subclasses. What is the difference here?" Kent asked.
So far, he has unlocked the Harem, Alchemy, Swordsmanship, Soul Cultivation, Guardian, and Servant Towers. However, among these six towers, only three had given him a profession, so he just couldn't wrap his mind around it.
[The towers are in two forms, Primordial and Mystical. Primordial Towers are designed to give you a class and subclasses once they are unlocked. The Swordsmanship, Alchemy, and Soul Cultivation Towers are examples of this.
Then there are the Mystical Towers, designed to aid the master in managing all the different aspects he wants to handle. For example, if you want to manage your women and ensure they grow along with you, the Harem Tower is designed for that.
