My fault. I knew it was something like this just hadn't found the rule.
The basic gist was that normal d&d magic rules don't really apply verbatim.
Annoyingly, for the SM, Estevan is a Paladin, and has Divine Grace. He probably has a respectable, if not phenomenal, CHA score.
PS: Using Mind-affecting magic, is probably a social stigma for Anuire. Every time I have seen such in RoE, it has been attached with significant social stigma (except in the cases of clerics, not surprisingly).
