Pathfinder: Kingmaker

The data on this trophy, is far and wide and argues with itself. I will list what I have heard, but can make no promises. You may have to play the game once, and get your own answers:
--Tartuk - there are sites that say you don't need Chaotic alignment to ally with him. I didn't have chaotic alignment, and I allowed him to depart, but I don't believe I got credit for befriending him. You should probably just reset your mc to chaotic for "The Trouble With Trolls." My alignment was Lawful Good.
--Hargulka - I don't know the prerequisites for allying him. I believe that if you kill Tartuk first, he will eventually cede and you can offer him friendship. You likely need chaotic to befriend him as well. To avoid any reloads, you should just grab Tartuk instead, unless you want to test his viability, yourself.
--Vordekai - He seems to be the only "absolute" villain that definetely counts for the trophy. You need to have evil alignment in order to obtain him. [[[this can potentially mess up the super secret ending trophy. You'll need to roll a 47-50 in perception in a much later chapter, in order to correct your path to obtaining the super secret trophy. I was able to obtain vordekai and both trophy]]]. Maybe make a hard save for each branch of destiny. There is a suggestion to make him an advisor in order for fully ally him. When I recruited him, I was Lawful Evil.
--Tsanna - It is unconfirmed if she counts. Different information from different sources. She is easily obtainable, though. Spare worshippers of the Mother of Monsters, including the goblins that Nok Nok specifically asks you to spare. After her questline is resolved (with the least amount of murder as possible), she will hang around the shrine and you can recruit her. I don't believe any type of alignment is neccesary, I was Lawful Evil at the time.
--Armag - Once more, I am unsure if he counts, as there is different information from different sources. Become his blood brother. Sparing his life is easy enough, I don't believe it requires an alignment, my alignment was Lawful Evil.
--Nyrissa - Her friendship/romance is extremely complicated. From breaking curses to making extremely specific dialogue choices. You're going to need an entire separate guide, just for her. And there are whole essays about it. Which is why you should definetely grab the other villains. She should be a backup, because your chances of obtaining her on your first playthrough are fairly low. Also, I will note that turning villains into allies is super helpful during the final chapter. They're very powerful
