The auction house. Buying and selling Slaves
I have made some experiments about this part of the game and this are my conclusions. Mind you, I have not give a look to the code, just played and taken some notes in a notebook.
There are two market slaves in the game. One in Watery Eyes and another in Chrystal Heights. You can put your fancy suit on, assign Armand as a follower (just in case, in previous versions he get you a discount, not sure if in this one it still work) and enter in an auction and buy slaves. The auctions are done during daylight, and you can assist to a max of 3 auctions per day.
There are a value number on the right top corner of the slave. Don´t let you fool with the drawing of the slave and pay attention to this number!!. In some cases the auctions get hot and if you want to get the slave you must pay a lot of money. As a rule of thumb, you should not pay more that 700$ per point of value.
Ok, you get your new slave in your household. You have buy her with the purpose of selling her (from the screen of actions). WAIT AT LEAST FOUR DAYS!. If you try to sell your slave too fast, the potential buyers will thing that there are something wrong with her, and you will get paid less.
Well, you need to improve your slave in order to pay service to the first trade rule, buy cheap, sell expensive. You can improve her corruption. You can improve her skills. Or you can decrease her willpower. This last one it´s, by far, the more cost/effective one.
There are a lot of things that you can do to decrease the willpower of a slave. the more cost effective it´s talking to them.
You can ask, dominantly, about her sexual preferences, three times.
You can explain, gently, her sexual duties. Don´t do it dominantly. The loss of willpower will not be higher and you are going to create anger that can make impossible to influence the slave tomorrow, breaking your chain of production.
If your Charm and Manipulation are high enough, that´s 6 points of willpower per slave per day. 4 slaves are a 6 hours work.
You can use also some passive effects.
You can put them in harnesses and collars, and make them wear small to medium butt plugs, and this help somehow.
In the last stages (will 9 or less), you can put one of them to work at Devious tools
You can assign one of them to blow you in the morning, and then humiliate her.
And if you have one slave mistress that decreases willpower that that´s an extra.
And you can make lectures in the shrine. Either to 4 slaves in training or to all your household. Mind you the even to just 4 slaves (just followers) it still affects the emancipation value of you house. If you are running the House of Mindless Zombies, that can be super effective.
All in all you need to put your slaves in NEGATIVE willpower. You get an big increase in price for willpower 0. And you get other big one for negative willpower. Yes, there are difference between will -1 and will -4, but its an increase, not a jump.
Usually the slaves you buy have willpower in the 25-40 rank. That means that you can break her in 4-7 days. Once you have achieved this and the slave have been in your household for 4+ days it´s time to sell her. Go to the action screen and check both slave markets. They will tell you an estimate price. Then, cross your fingers, hold your breath and send your slave to the market with the higher estimate price. On average you will receive between *1.5 and *2 of her buying price.
It´s a very cost/effective use of the time of your MC once you have cleaned the map, finished your academic courses and raised a good manipulation and charm skill. If you can process 3 slaves per day you can get more money with this strategy that going chasing Lvl 4-5-6 bounties. Sadly, it´s not for me, because its a lot of clicks and a lot of micromanagement, and I don´t want to run the shrine trick ( My house it´s high in willpower and emancipation. and in corruption also) but may be fine for you...
