How did you got the "Slut" class, and what does it does exactly?
You can get the "Prostitute" class if you get enough levels of Lady of the Night, tho I don't know for sure what it does.
The "Mare" class is from dealing with centaurs, and I think it lets you join their camp without getting the bad end.
You can also get the "Queen" class from the Beastmistress Drow... but it's a bad end.
And I think there's a "Gobbo fuck-toy" class as a bad end on the Patreon version, not really sure.
