Towards the end of the game, in the "House at the End of Time", you have to save your companions. Chance of saving them seems to depend on the resolutions of their personal quests:
Spoilers ahead
- Amiri: In act 4 (Twice Born Warlord) I've done the "Hour of Rage" first, saving most of the barbarians and most important her friend. Later on, when her tribe was held hostage by a ghost giant, Amiri sacrificed herself, after I've asked her to sacrifice me instead (she got better).
- Valerie: In the prologue, I've helped her taking care of wounded soldiers; won a duel with her old master (damn, damn hard fight!!!) and let him go. When she was acting up, I've convinced her to calm down and apologize. During her judgement, she apologized and was forgiven by the goddess (her scar disappeared)
- Harim: here my memory is a bit fuzzy: let him destroy the magical anvil, then the same with golem. In the last quest, I've sided with the dwarves and destroyed the magical throne. I'm not sure about the consequences of the conversation afterwards, but he accepted the fact, that he is not cursed (but he still follows his god of destruction).
- Octavia: Not much to decide here: When I found the Technical League hideout, I let her old master run away and saved the slaves. Later on, I've visited her mother in Pitax (I don't think that I had to convince Octavia to forgive her or anything).
- Regognar: The same quest as Octavia - I let his old slavemaster to run away and saved the slaves. When found his tribe, I've buried the bones.
Not sure is it important here: I was romancing Octavia but after the first meeting I didn't reply with "I love you too" (I was still able to keep sleeping with her!), so in the ending I didn't have any suggestion, that I was still with her - instead, it was information, that Regognar was thinking about proposing himself.
- Jubilost: won the fey competition without hurting anyone. When meeting the Host again, Jubilost decided to give immortality to some random, dying ("bleaching") gnome, who saved him in the end.
- Ekundayo: I let the kid-trolls go in act 1, I told him it is time to stop his vengeance and find new bury his past, siding with the tavernkeeper. In the House, when facing near-unkillable troll, I simply walked away with him in my group (I didn't have to convince him to walk away, even while it was in the options, I just said "we will kill it"... and I didn't :P)
Unfortunately, I was unable to save Jaethal and Nok-Nok (and to a degree Tristan):
Nok-Nok: I let him build his temples, but when facing the false Goblin King, I simply killed him instead of tricking him. This made Nok-Nok doubt, that he is a hero, so he was killed in the House.
Tristan: I forgave him, followed his quest chasing the monster-cult. In the end, I've saved the final sacrifice, but after Tristan was forgiven by his goddess, I've said "do what you want" and he became a deva (but still stayed with me). In the House, he says that "he has been deceived again" and killed Jaethal.
Jaethal: Most problems here: I've convinced her to kill the undead girl she just created, then I've learned the magic ritual and kept my word and risen the old priestess. In the showdown with elves, I let the inquisitor kill her daughter. I was trying to convince her to stop, but I couldn't, so the only options were either sacrifice the daughter, possess her body or attack Jaethal. I let her decide and she has chosen the sacrifice. In the House, she is convinced, that she must kill Tristan.
So, with that long wall of text (that I hope will be helpful to someone), can you tell me, how to save all companions and bring most positive endings?
