the bonus levels are not clear, since it's really hard to track/test. if we knew what to look for early on we could have asked ppl to write down levels in their S2 save that is used for S3 and write down what level they recruited the characters relative to the recruiter's level....... also it wouldn't be a good idea to recruit with a level 99 character because you can't tell if they are supposed to join based on the recruiter's level + bonus.
