Chapter 166

Looking through his skills, and what the book tells him of the class, most of it based on one single example who should have only just started down the Lord side of the skill tree after finishing the General side and not choosing to try for a more advanced class right away, Cain comes to a realization. 

The next skill he will be able to get is [Lieutenant] which the book says is in two parts. Either Summoned or Appointed. Summoned doesn't have details, other than that there are two to start with, but Appointed ones, the version the city leader uses are like his own Appointed Companion skill. They get the bonuses from his Summon related abilities. 

It would be nice if there was more information, but with only one sample used in this book they were limited to what he could or would provide.
