Btw, is there a guide on beta? I've read the alpha but I need to know the deal about the "Tier" system. Are there limits to starting out and prohibited use of such girls? Why can't I hire Maxed out girls? Why my slave won't fight in combat? She is part Assassin tho
Nope, no guide, we'll be adding a limited of "PyTFollopedia" in the game itself, similar to Civ games and will be expanding that as we move along. Assassin slaves come from modder packs, as the previous version of the city was nuked in the major slave revolt, slaves are forbidden from doing any kind of combat, in the future, this and other game world rules could be influenced through politics. You'll be able to free slaves in the Beta release as it comes out of the testing phase.
Maxed out girls will refuse to get hired by a low-level mc and you will be meeting better ones as you advance. Rule of the thumb is that one tier is about 20 levels but that also depends on stats and skills so tiering up can happen earlier or later than that. You normally want to use girls of the same or higher tier than the building they work in.
You can get more AP by increasing constitution (same as it was in Alpha) though items/events, maybe chopping wood. One of the trainers has a small chance of increasing that as well although those are majorly expensive.
