I noticed some minor inconsistencies. For example, the system says the original owner was Lv.1 with 100% experience and could change profession, but he failed repeatedly. That implies the job-change itself has a chance of failure, not just lack of faith. But later the narrative treats the job-change as something that worked only because of the unknown being. Also, the attribute values post-change don't exactly double (some go from 4 to 8, 6 to 12, but the base was 5 average, so maybe I misread). It's not a big issue, but it made me re-read. Overall, the logic holds up.
