Bab 2307: "Shamans' Honor" 

The man got a lot of news from the outside world so he knew that Ainsley's first spirit was about to disappear, which was why she needed a replacement to prevent the backlash from the first spirit. 

However, if the replacement was a beast spirit...no matter how strong the spirit was, they could not block the backlash because they were of a different race! 

This is why most shamans would not contract beast or plant spirits if their first spirit was a humanoid spirit. 

There were too few beast and plant spirits, so naturally, most shamans only had the humanoid spirit as their first choice. 

Then, they would not want a beast or a plant spirit as their second spirit. 

Not to mention that shamans who could contract two spirits were too few in number. 

The shaman guild master herself had only contracted two spirits so far even when she could contract the third spirit.
