As far as I know, adventurer and scout only come through recruiting. So hiring more gals helps.
There's a lot of different stuff in this version, I haven't played in a while. Most of it is good, I feel like the mixed clothing mechanics to make bandages and pirate clothing, plus not being able to buy more adventurer clothing, is kind of needlessly restrictive IMO, but I'm still loving it. You'd think you'd get mixed clothing from at least every two corpses, if not -every- corpse. Most of them ARE wearing clothing after all.
