Knowing how to clear Subnautica 2 Bloom Cankers and save the Angel Comb is unavoidable if you want to continue through the campaign, as it leads you to an important ability. Disinfecting these sick coral structures in Subnautica 2 can seem like a confusing task at first, as you avoid dash attacks from deadly fish and follow underwater tendrils. However, once you have the right tools for the job, it’s a straightforward process.
Angel Combs hide DNA-altering Adaptations in their core, which, when accessed, allow you to survive the ocean more efficiently. It’s likely you’ve already run into one or two healthy Angel Combs on your journey so far, which have imbued you with the ability to breathe pressurised air and digest alien fauna like Water Slugs and Geordies without getting sick. Our guide explains how to cleanse the sick Angel Comb and deal with those pesky Bloom Cankers.
How to clear out Subnautica 2 Bloom Cankers and save the Angel Comb
The Subnautica 2 Angle Comb sickness is caused by sizable floral growths attached to the Angel Comb, known as Viral Blooms. To dispose of the Viral Blooms, you’ll need to destroy a glowing mushroom-like cluster at the core of the Bloom, which is called the Bloom Canker.
These can't be destroyed with your Multitool - you’ll instead need to craft the heavy-duty Subnautica 2 Sonic Resonator to destroy these destructive Bloom Cankers.
The difficulty in this quest comes from finding all of these Bloom Cankers. To do this, swim down to the base of the Angel Comb to find its ‘roots’, which resemble deep-sea fibre optic cables.
Select a root and follow it along the sea floor until you come to an endpoint, an area that looks like a tree trunk with flowers growing on it. You’ll know you’re in the right place when your PDA pipes up to explain that the area is called a viral bloom. You should see a series of blue, glowing, mushroom-like clusters – these are the Bloom Cankers. To dispose of each canker, pull out your Sonic Resonator, aim at the node, hold the trigger and release.
Once you’ve got all of them cleared, head back to the Angel Comb and complete the same process for the other roots. Once you’ve destroyed enough Bloom Cankers on the Angel Comb’s roots, Bloom Cankers will then appear on the 'mother' in the central cavern where you first found her. Destroy them all one final time, and the Angel Comb will open up, revealing its gooey purple innards with which you can interact to obtain the Subnautica 2 Heat Tolerance Adaptation.
While optional, we suggest unlocking the Wakemaker mobility tool for this process, as it lets you zoom around the ocean much faster and complete the job without taking unnecessary damage or running out of air. As with other tools in the game, unlocking the Wakemaker requires you to scan Wakemaker Fragments to unlock the Blueprint and then craft it at a Fabricator.
Subnautica 2’s aquatic setting is eerily vast and often dangerous. If you find yourself struggling to become one with the ocean, we’ve got plenty of guides to help you find your footing. No matter whether you’re struggling to stockpile resources like Subnautica 2 Lead or Gold, or are trying to smelt Subnautica 2 ingots for a new recipe, we’ve got you sorted. Plus, we’ll continue adding guides, so be sure to check back if you get stuck.
