Halibut

Halibut is the first companion you pick up in the story-adventure content. Fish up the legendary Halibut weapon, hold it, and finish her first-meeting conversation. From then on she travels with you and chimes in for the rest of the run.

After boss kills she hands you a fish. Once you’ve banked enough common fish she may pitch a fish-oil commission. If you take up the Brimstone Witch’s line, she tries to talk you out of it.

This page is about who she is and how the line begins. The details live on the subpages:

Subpage	Covers
Boss gifts	A fish after each of 22 boss kills, plus a one-off gift in the Underworld
Fish-oil commission	Hand over 300 common fish for Fish Oil
Branches & everyday scenes	Revival warning, her interference with the Brimstone Witch line, dye protest

Character

Before you reel her in she’s just an unnamed shape in the water, listed as ”???” above her. Once she’s on dry land she gives her name and tells you to call her Dr. Halibut, or just Halibut.

Thanks to your hook, I was pulled out of that silent, dead water.

She says she was a professor at Sulphurous Sea University, in the Department of Abyssal Research. A few years back the department ran an “Abyssal Ecological Sampling Project.” The team dove to the bottom of the abyss, ran into something that could neither be killed nor understood, and she was the only one who made it back.

While fleeing, she found an eye beneath a coral tree and swallowed it on instinct. Its power let her open a domain and tear an escape route out of the abyss. Then her memory blurs and she slept, until your line pulled her up. Her terms for coming along are blunt:

If you’ll have me, take me with you. I will help you conquer this land. In exchange… help me solve this… ‘revival’ problem with the eyes inside me.

She was once a colleague of the Old Duke at the same university. If she is with you the first time you meet him, she vouches for him.

Her portrait shifts with her mood as a conversation moves along.

How to start

1. Fish up Halibut

Fish any water that isn’t honey or lava for a chance at the weapon itself.

Situation	Chance
Never caught it before	about 1 in 10
Caught it before, none in your inventory	about 1 in 500

The first time you get the weapon, the game records the catch for good. During the epilogue of the Brimstone Witch’s [BE] ending, fishing always turns up another Halibut.

2. First meeting

Requirements: hold Halibut, first meeting not done yet, and no other conversation or cutscene playing.

On the sixth line she holds out the bass in her hands, saying it should have been your catch:

This fish should have been your catch. Now, it’s a gift to mark our meeting.

You get Bass ×1, and the conversation runs on through her backstory and her offer. When it finishes, first meeting is marked done and she starts traveling with you.

3. Later content

Most Halibut scenes need first meeting done and Halibut in hand. Two exceptions:

• Her interference: Halibut just needs to be somewhere in your inventory.
• Underworld gift: Halibut in your inventory, and you standing in the Underworld.
