Starting Location: Bad Seed

The quest giver, a woman named Lysett, can be found in the north-east of Dominion’s Carcadia District. She’s on an elevated floor which you can climb from the north. Main Mission 18: Means of Ascent.

Take bioengineered seed

The quest puts out her hand and offers a seed, take it.

Note: this quest has several lengthy enemy encounters, if you’re underleveled and they show red skull icons you would have a hard time. In this case it’s better to come back later after leveling up. I was level 38.

Reach facility entrance

The entrance is 200 meters north. It’s up at a red gate where the yellow water comes from. Use the grappling points on the side to get up there. The location line will guide you to it.

Open facility gate

After you head into the first facility section, press the button at the gate. However, the gate is stuck and won’t open.

Unblock door

Go to the cogwheels in the north-west corner of the same room. There’s a metal piece stuck inside the cogwheels, pull it out.

Make your way into facility

The gate will now open. Head inside and climb the ladder at the end of the room on the right. In the next room use a grappling point, climb a ladder, and another grappling point to enter an air duct. Here pull the grate and drop down the air duct. Enemies will spawn in the next area.

Defeat security

Kill all enemies in the room. This is a lengthy fight with many enemies. If you’re severely underleveled and the enemies show a red skull, you may want to come back to this later after leveling up.

Hack security console

Jump up the platform in the middle of the room and use the computer, it will be outlined in green.

Enter maintenance shaft

Straight ahead of the computer, enter the tunnel.

Reach transistor capacitator

Go through the tunnel to reach this. Watch out for the engine fire along the path.

Spin transistor’s turbines

Grapple the points on the turbine, two times each to make them spin.

Return to transistor room

Go back to the previous enemy room, more enemies will spawn here.

Defeat reinforcements

Kill the new wave of enemies.

Overcharge transistor

Go through the door where the reinforcements came from, on the north side of the room. From there go upstairs to press a button in the command room.

Enter core room

Leave the room through the south side, opposite where the reinforcements spawned. That’s the core room.

Defeat facility director and guards

More enemies appear, kill everyone. The director is the main enemy and has a lot of health.

Put seed in core

After the fight, interact with the green outline on the yellow glowing machine in the middle of the room.

Overcharge core

Use the switch upstairs behind the yellow machine.

Pick up seed

Grab the seed from the machine floor.

Leave facility

After picking up the seed, the quest giver will call you and tell you to come see her again. The quest will end here immediately. She will offer the follow-up quest Bad Seed Pt. 2 later in Fades District (southern part of Dominion), which becomes accessible after completing Main Mission 18: Means of Ascent.

This finishes Bad Seed side mission in Borderlands 4 and unlocks the next mission Bad Seed Pt. 2.
