After a decade of Dr M, his student is annoying to play (maybe just for me). It used to be, for most checks the margin of success is binary. You can pass by one or a million, in most classes it doesn't matter. Dorothy means that every time you investigate, you have to do the math again, running a checksum of (total-penalties = 1 or 3).
Not that you won't appreciate the money, but without some of the combo pieces released with Drowned City, it's going to be tough for seekers to adjust their results, and you'll need to get the test four times over four turns to make her revenue neutral. Still, even mutated Dr. M was one of the best Seeker allies ever, so maybe this is what it looks like when you get a stat bonus, random $ and soak.
