Oopsie. Sometimes it happens, LR.
As I understand it - Larry Niven's character for whom things always worked out the best no matter what - put him into a wall because, if I remember rightly, no matter what happened she was gonna come out of it smelling like roses and all the other characters around her would be moved by fate or luck or whatever to make things good for her. He was not best pleased because she'd already been introduced into the stories.
As for your problem in regards to Mooks/Fuego fodder - how about some form of necromantic mooks.
The bad guy magic users can create a limited number and for a limited time and/or with someone they know or someone who is a blood relative of their enemy - a type of zombie. Alive/dead. The good guys can't just take out these possessed souls - Pombies - because many of them are still alive. (Perhaps the longer they stay under the spell the closer they go to being truly dead.) So the good guys are forced to work, quickly, carefully, and very circumspectly.
