You need to be nice to Aligern and complete his quest. This one pops during the ending sequence.

Oom: be mean to him and do not let him touch you tell him he disappoints you.

Tybir: during his quest, allow him to kill Ragmin in the Shrine of Great Chila.

Callistege: do not give her the book (found in Buried Crossroads) she wants.

Matkina: do not help Clarion in the Fifth Eye Tavern with recruitment agree with Paj during first conversation in Miel Avest and afterwards tell Matkina that she is just a jerk that interrupted a nice conversation you were having with Paj (very important) do not help her reconcile with Melmoth in Miel Avest (very important) feed her to the Maw in the Shrine of Great Chila.

Rhin: be very mean to her during conversations with her (tell her you think she is out of her mind, tell her that what you do is your business not hers, tell her you love using the Tides to force people to do stuff, tell her to shut up etc.), persuade Loss-of-Self to jump of the cliff kill Aidan Sitabo after defeating him be mean to everybody around sell Coty to the Decanted feed Aligern and Matkina to the Maws.

Erritis: give (or try and change your mind) Rhin back to the slavers persuade Loss-of-Self to jump of the cliff kill Aidan Sitabo after defeating him kill rogue Stichus in Cliff’s Edge try to sell Rhin to the Decanted tell Skoura that you want to make Erritis stronger and than tell the same to the Audience.

Aligern: claim that you are Changing God help the Foreman in Underbelly make children and than take them all as numenera agree with Min of Tan Liang instead of Aligern during conversation in the Order of Truth give (or try and change your mind) Rhin back to the slavers persuade Loss-of-Self to jump of the cliff kill Aidan Sitabo after defeating him try to sell Rhin to the Decanted tell Aligern to use his tattoos more (very important) don’t take him with you when you talk to Aadiriis in Miel Avest (very important) feed him to the Maw in Little Nihliesh and do not pull him out.

If someone want to share his own experiences of what various companions disapprove of, I will gladly add them below. I do not have extensive experience with disappointing all the companions, so descriptions below are not very detailed for all of them.

Feed a companion (or two if you have Rhin with you) that still doesn’t hate you enough to Aen-tozon Little Nihliesh – this guy feeds on positive relationships.

Resolve their quests in a way that they do not like or don’t do them at all.

Aligern will leave if you actually sell Rhin to the Decanted) – you want them to stay and hate you, not hate you from afar. Be careful here though, some acts will make companions leave you for good if they already dislike you enough and you don’t want that (e.g.

Do not buy them clothes upgrades in Miel Avest.

being a test subject for Demeray and Obervich in the Bloom).

Force them (usually by Persuasion or Intimidation) to do stuff they don’t want to do (e.g.

Be awful to your companions, always tell them to shut up and always be clear on how little you think of them.

You can also see that companions’ opinion of you changed when they change their answer to “how you’re doing?” question (exception: you can see Oom’s opinion of you changing by his reaction to you petting him). Also, when what you do or say causes a big shift in an attitude of a companion towards you, you will get a helpful message saying that their opinion of you improved or worsened.

This one is a bit more tricky – being hated is not as easy as being loved, who would have though ). So you only need to make 3 companions hate you. Only your current (and full) party matters for this achievement, not all the available companions. The entire party dislikes the Last Castoff. For example, Rhin, Erritis and Aligern ike when you help the weak and generally act in a hero, Gold-Tide kind of way. Buy them clothes upgrades in Miel Avest.Do their quests and resolve them in a way that benefits them.Be nice to them in general and never force them to do something they do not want (e.g.

So you only need to make 3 companions like you. Those unlock as you progress though story of the game.
