The whole walkthrough

Before you start

Chapter 3 is linear. You can't return to your ship or the star map until it's over. Your party is split up, and your gear is taken from you. The goals, in order, are:

1. Find your companions (Reunion).
2. Get your gear back (The Chasm and the arena).
3. Survive the arena and deal with Marazhai.
4. Beat the final boss and escape (Strings of the Puppeteer).

Some companions that join here are missable. Read each section before you move on.

Opening: Troubling Developments

The chapter opens with your capture in the von Valancius Palace and drops you into Commorragh. Several quests start at once:

• One Foot in the Grave
• Reunion
• Not the Biggest Problem
• Following Breadcrumbs or Hunting the Hunter. Which one you get depends on whether you recruited Yrliet in Chapter 2.

Explore every corner of the first areas. You are weak right now, so pick up anything usable and avoid fights you don't need.

Reunion: finding your companions

Reunion tracks down the companions who were captured with you. Before your first arena fight you can get back Abelard, Argenta and Yrliet (if you recruited her). Other companions turn up later in the chapter.

• Some companions need you to pass a dialogue check to stay on your side. Save before these talks.
• Only the people who were taken with you are available here. Plan your party around them.

The Chasm and the first arena fight

Your gear is held in the Anatomical Opera. To get there, you go through The Chasm.

1. Work through The Chasm and enter the dimensional portal.
2. Defeat the enemy marked as Malice, or the one with the "Commissar" icon, to move on.
3. Win the arena battle. Fight from cover and use the arena's choke points.
4. In the Anatomical Opera, find the "maestro of flesh", Tervantias the Archmachinator, and get your items back.

Ulfar, the Space Wolf (missable)

A Space Marine of the Space Wolves, Ulfar, is held by Tervantias in the Anatomical Opera. This is the Fury in Chains errand. If you miss him here, you can't recruit him later.

1. Find Ulfar's cage in the Anatomical Opera.
2. Get the Bone Key and use it to free him. Guides also describe talking Tervantias into letting him go.
3. Loot the chest on the left side of the cage. It holds Ulfar's Astartes gear.

Ulfar is a superb front-liner. He makes the rest of this chapter much easier.

Marazhai and the second arena fight

Your second arena fight is against Marazhai, the Drukhari who captured you. After it, the quest Last Will starts.

• Marazhai can become a companion, but recruiting him is tricky and he does not always survive. Your dialogue choices decide it. Save before talking to him.
• Like most Drukhari, expect him to hit hard. Keep your tank between him and your ranged characters.

The optional quest The Worm Churns ends with its own boss, Kilkaross, her Drukhari squad and a machine that shields her. Take out the shield machine first.

Final boss: Iremeriss

Iremeriss (also written Yremeryss) is the boss at the end of Chapter 3. Many players report that she can wipe a party in a few rounds.

• Focus her down. The fight is all about killing Iremeriss fast.
• At half health she heals back up and two turrets appear. You don't need to destroy the turrets: they vanish when she dies.
• Bring a tanky front line (Ulfar is perfect), strong damage dealers, and an Officer who can hand out extra turns.
• Use stairs and narrow spots to funnel her guards so they can only reach your tank.
• Save Momentum for a Heroic Act on Iremeriss after she heals.

Escape: Strings of the Puppeteer

Once the way out opens, Strings of the Puppeteer leads you to a portal into the webway.

• Loot everything before you go. You won't be back.
• Make a hard save right before the webway gate. Chapters 4 and 5 are harder to fix if something went wrong here.

Walking through the portal ends Chapter 3.

Tips for this part

• Save often, in new slots. This is the chapter where people most often get stuck with a bad party.
• Recruit Ulfar. Even if you don't plan to use him later, he carries you through Commorragh.
• Drukhari have low armour but high damage. Cover and focus fire matter more than ever.
• If Iremeriss wipes you, lower the difficulty for one fight. It is a known spike.
• Talk to companions you reunite with. Some conversations here affect whether they stay loyal.

My take

Commorragh is grim, cruel and honestly brilliant. Losing your gear made the early fights tense in a good way. Iremeriss took me three tries and one very lucky Heroic Act. How many attempts did she take you?

FAQ

How do I get my items back in Chapter 3?

Go through The Chasm, win the first arena fight, then find Tervantias in the Anatomical Opera. Your gear is there.

Can I miss Ulfar?

Yes. He is only recruitable in the Anatomical Opera in Chapter 3. If you leave Commorragh without him, he's gone for that playthrough.

How do I beat Iremeriss?

Focus all damage on her. She heals at half health and summons two turrets, but they disappear when she dies, so ignore them.

Can I go back to my ship during Chapter 3?

No. The chapter is linear and you stay in Commorragh until you escape through the webway.
