Okay, so as I understand it, the only way for a Villain to inflict more than one wound with a Raise is for them to purchase a Duelist Style with the pool of Advantage points they start with (Strength+5).
But, if a Villain does purchase a Duelist Style, should they also get that school's special maneuver? Personally, I see the special manuevers of a school as being something for the PCs to make use, giving them that little bit extra flair to make them that much more distinct. Plus there's the notion that a combat-orientated Villain with a high Strength (6 or more) has already got enough going for them (Heroes need to inflict more wounds to cause a Dramatic Wound, Villains can change their 'approach' without penalty, have Danger Points aplenty where Hero Points are a more limited resource) that adding the special maneuver of a Duelist style just seems like it's overkill.
Came upon this particularly quandry while working up some sample Villains for a future blog post, one of whom was a stereotypical Vesten raider. From what I understand by RAW, if I purchase Duelist Academy for this brute (Strength 7), and pick Leegstra (suits him really well), then he'd be able to dish out some pretty frightening damage in three consecutive raises (Slash -> Leegstra Crash -> Slash), leaving most Heroes reeling from that much punishment, especially if the Hero isn't themselves a Duelist. Granted, this Villain is offset by a fairly low Influence (only a couple of points, enough so that he can call up a Brute Squad on short notice if need be), so he's not rolling lots of dice (I figure on average he'll be able to make between 4 to 5 raises on his Risks).
