We'll BLAM, ok? Theorycrafting killing all companions playthrough.
I'm traveling. Im bored, hench this post.
Rules are simple, Companion must be recruited before blaming, and rt cannot feed certain companions to Heinrix.
Act 1: No companion can be killed on act1, so progress the act as should. Pick the fish from the station, get doormat fanwank waifu...i mean Kibellah when approaching Rykard Minoris, get Pasqal from airport and Heinrix from power plant. Join deathcult and do different walks of life if feeling like it. Finish act1.
Act2 : pick Jae from footfall, do Argentas footfall quest, return to ship after picking Heinrix.
Now this is where the fun begings.
After some warp jumps you get Idiras warp event. Unless you specially go to save her, Idira dies ether by airlock or adepta sanctimonius bolts of seeth.
Progress to Janus and recruit Yrliet. How Muaran is handled dosent matter.
On west of Janus there is the dark pit and it asks for an sacrifice. Luckily your senechal is allways there for you.
After returning to Janus Dargonus during spiders in the jar, Yrliet sneaks into lord captains wraithbone wallhanger and miniature figurine collection. For this transgression she must pay with her blood.
Start Jaes romance and progress it to the part of that boardcast. [Execute the smuggler] For making a mockery of the Rogue Trader, I sentence you to death.
Now all theres to do is waiting for act 3. And boy.
In act3, our shortlived team is those whom remaing, Argenta, Pasqal, Kibellah, Heinrix and Cassia. Pasqal has been moggled and beaten and waiting to be finished off by someone. Luckily our hero Rogue trader is there to save the day!
Argenta you meet on the chasam with """"comissar"""" and can die with him.
After arena fight, Tervantrias funhouse is open to us. First things first, after awakening from med table, rt must stroke his ego and asks to "safe" one of their companions. Lets go with Cassia first, open the pod and you're given straight away option to shoot her. Unfortunately Heinrix is timegated now until after second arean fight. Kibellah is on other end of the opera on cage with her close friends. Tell her to kill herself...ahem themselves, or do it yourself. Tell Marazhai that you need fighters for escpape. If rt has atleast one crafting material, they can suck Haemonculis ego bit more and take space wolf with them.
Done with second arena fight pick Marazhai, save Marazhai from ulfar, go pack to opera to pick heinrix but just lock him to the box instead. Progress in act3 normally now.
Coming to act4 theres only one companion we can kill - Marazhai. Lucky for us, all we have to do is one warp jump. Option is to do it personally or vent whole section. Ether works.
Last but not least we have to get rid of Ulfar, and it can be done all the way in act5. When Ulfar steals an shuttle and Leeroy Jenkises himself to the ice planet just...leave him there to die than send rescue mission to pull his Astartes ass from grasp of death at last minute.
And there it is. If theres more optimized route or oppoturnity to kill companion earlier, feel free to correct.
