How to Unlock Symbiosis

Find Three Lost Items From the Old Capital in Hollow Zero

The Symbiosis commission can be unlocked once you find all three Lost Items From the Old Capital in Hollow Zero. For Symbiosis, the items will appear after getting all items for The Hollows Bank and The Sanctuary.

Hollow Zero Guide and Rewards

Reset the Stage to Get Lost Items Faster

Old Capital Metro Lost Item Locations
Frontline 1			Frontline 2
Interior 1		Interior 2		Interior 3

Lost items are collected from Secret Path tiles in Hollow Zero, and you can get up to 3 items per day. You do not need to complete Hollow Zero stages to obtain Lost Items as quitting lets you keep them.

We recommend loading up a stage like Old Capital Metro: Frontline or Interior, checking if a Secret Path tile is present, and exiting and reloading the stage again until the Secret Path tile is present.

Old Capital Metro Guide

Pay 2,500 Gear Coins to Weird Girl

One of the encounters is with a Weird Girl asking for 2,500 Gear Coins. Collect 2,500 coins in a single run and keep going until she appears on another floor. Due to the randomness of the encounter, it's possible she won't appear again in the run. You can keep trying again or choose a different stage like the Construction Ruins or harder stages to increase the chance she reappears.

Pay 5,000 Gear Coins in Total

For the last item needed to unlock the Symbiosis commission, you'll encounter the Weird Girl again. This time, you need to pay her a total of 5,000 Gear Coins. This can be spread out through multiple runs. You can get Gear Coins through events, defeating Ethereals, and by collecting them.

Talk to Biologist

Afterwards, talk to Biologist, also known as Scholar Studying Symbiosis, in Scott Outpost to receive the commission on the HDD.

Best Teams for Symbiosis

Best F2P Team and Bangboo

Best F2P Team			Bangboo
Anby	Billy	Nicole	Avocaboo

The starter trio of Anby, Billy, and Nicole is a great F2P team capable to complete this commission. Nicole is a great Support Agent to bring for this comission because of the enemy's weakness to Ether attacks.

Avocaboo is also a great Bangboo of choice for the team to provide your Agents with heals if they need it.

Premium Team and Bangboo

Best Premium Team			Bangboo
Lycaon	Soukaku	Ellen	Sharkboo

We recommend the team of Lycaon, Soukaku, and Ellen to exploit the Ice weakness of the enemy. Soukaku provides a large Attack buff to Agent swapping in after her, while Lycaon increases the damage multiplier against stunned enemies for Ellen.

Symbiosis Quest Walkthrough

How to Beat Symbiosis

1. Destroy 50 Obstacles
2. Defeat Enemies Inside the Ring
3. Retrurn to Biologist

Destroy 50 Obstacles

The first portion for Symbiosis requires you to destroy 50 obstacles. We recommend ignoring the enemies that spawn and focus on breaking the boxes and canisters scattered throughout the stage.

Defeat Enemies Inside the Ring

Once the area is clear, secure the blue ring around the device by standing inside it and defeating enemies that go inside.

The goal for S-rank is to reach 100% on the progress bar before the clock hits 2 minutes, so prioritize enemies found inside the ring first!

Retrurn to Biologist

After completing combat, return to Scott Outpost and talk to Biologist to complete the commission.
