There were hundreds of lifestyle classes in the King of Pantheon. The majority of them were available when the game was released but only a few of them such as Engineer were activated through unique quests.
The majority of the lifestyle classes had levels. They were Beginner-level, Intermediate-level, Master-level, Grandmaster-level, Epic-level, and Legendary-Level respectively.
The benefits it could bring towards the players increased as the lifestyle class level increased. In order to increase the level of the lifestyle class, one would have to spend a lot of time and money on it. Take Li Yi's Apothecarist class for example. He had been training for half a year since the server was opened and he was only able to reach Intermediate-level even with the required ingredients.
One could see that it was not easy to reach to the very top.
