Every saint-level powerhouse, whether it is from the human race or the monster race, has a title which was also called a saint title. It was the proof of acknowledgment of a saint's attainment regarding their title.
For example, Sophia's master was known as the Ice Saint since that old grandma was very proficient when it came to controlling and creating the element of ice. In other words, when it came to the element of ice, she was unrivaled.
Knowing a saint's saint title also meant that one could discover the field or element that they were proficient in. And by doing so, one would know what kind of existence they are up against.
With that intention in mind, the Wolf King asked Alister about his saint title. As long as he discovered Alister's saint title, he would be able to make some contribution to his race and his failure to eliminate Sophia would still be ignored by the Monster Saint due to his contribution.
