Magnificence, the big tiddy dragon MILF queen, has a thing for slutty bimbos and wants to collect them as "trophies". Basically they're bimbo transformations where the subject becomes a trophy harem bimbo slut loyal to Magnificence. NGL they're my favorite transformations so far, but getting them is relatively complex and currently IIRC only two aren't mutually exclusive to any other (i.e. you can get those two in a single run/path but the other two you can only get if you don't have any other trophy transformation).
