The first word of the hidden-occupations name didn't tell him anything as it was a simple 'Descendant'.
This could lead him to literally every single occupation, or even possible awakened affinity!
Had he received any more clues such as [Thundergod], [Burning], or [Tamer], Shane would have been able to comprehend some of it, but 'Descendant' didn't really provide him with any useful information.
Nevertheless, Shane couldn't complain. Instead, he was glad to have accomplished the first requirement of the hidden occupation that was the most likely to benefit him.
There were other occupations Shane had unlocked while completing his missions, with many at the [Platinum] quality, but there was none that looked as promising as the hidden occupation!
Now that he had solved the Innate taming skill's upgrade mission, Shane decided to take the next step that would allow him to become as strong as possible during the next few months.
