"How is the elemental affinity considered to be good?" Tyrion asked.
"The higher the elemental affinity, the higher the value of the elemental talent detected. For example, a normal person's elemental affinity is only within the range of 1 to 50, and those with more than 30 are eligible to become Chemists." Taergarien said.
He then whispered, as if he were sharing a great secret, "Someone with an elemental affinity between 30 and 50 would be detected with a greater value of elemental talent. As such, the chances of becoming a Chemist would naturally be higher for someone with a value above 50. So, in general, the higher the elemental affinity, the higher the elemental talent."
He then added one last piece of crucial information. "As to whether there is a limit on elemental affinity, no one really knows. In the past, there were geniuses, who were said to have values of more than 100, 200, or even 300!"
