- To clear Subnautica 2 Armored Pox (Bloom cankers), you need the Sonic Resonator.
- Some cankers require the Feedback Resonator mod for armored versions.
- Destroy open Bloom cankers first to reveal armored ones.
- Follow the Bloom branches to locate all infection sites.
- Flares are useful for distracting aggressive creatures in infected areas.
Understanding the Viral Bloom and Armored Pox
Zezura is under threat from a mysterious bacterial infection known as Bloom, a virus that devastates everything it touches. This infection isn't just a visual nuisance; it blocks access to crucial areas, preventing you from acquiring vital adaptations and resources like gold and lithium. The Bloom manifests in various forms, including biofilm, cankers, sap, and parasites. While the basic Bloom can be cleared with the Sonic Resonator, some advanced forms, often referred to as "armored pox" or armored cankers, require a specialized approach.
The Bloom infection spreads through parasites and blocks significant portions of the map. Failure to clear it will limit your progression and access to essential materials and adaptations.
To effectively combat the Bloom, you'll need the right tools. The primary tool for this task is the Sonic Resonator, and for the tougher, armored variants, an upgraded version or specific technique is required.
Acquiring and Upgrading Your Resonators
The Sonic Resonator is your first line of defense against the Bloom. This tool uses sound waves to break through various materials, including the Bloom infection itself.

Finding the Sonic Resonator
The blueprint for the Sonic Resonator is crucial. You'll find it near the Blackbox - Wander signal. Noa provides the coordinates to this location after you discover the remains at the Blackbox - Ruby signal. Look for a discarded Sonic Resonator inside an open box on a table, usually found near an entrance blocked by Bloom biofilm.
Scanning the discarded Sonic Resonator will add its blueprint to your Fabricator, allowing you to craft it as needed.
Crafting the Sonic Resonator
Once you have the blueprint, crafting the Sonic Resonator is straightforward:
| Component | Quantity |
|---|---|
| Basic Battery | 1x |
| Wiring Kit | 1x |
| Titanium Ingot | 2x |
| Lead | 2x |
Dealing with Armored Cankers: The Feedback Resonator
While the standard Sonic Resonator handles most Bloom forms, armored Bloom cankers often require an upgrade. Players have noted that "armored" or "closed" cankers might need a specific mod for the Feedback Resonator. This advanced tool allows for distance destruction of these tougher infections.
| Resonator Type | Target Bloom Type | Destruction Method |
|---|---|---|
| Sonic Resonator | Open Bloom Cankers, Biofilm, Sap, Parasites | Direct application, close range |
| Feedback Resonator (Modded) | Closed/Armored Bloom Cankers | Specific distance shot, reticle turns green when in range |
The Feedback Resonator mod is essential for later stages of Bloom eradication, particularly for cankers that remain closed or become armored.
Clearing the Viral Bloom and Armored Pox Sites
Clearing the viral Bloom involves destroying multiple cankers and parasites across infected areas. Your PDA and Wander will often provide audio cues to guide you.
Locate the First Infection Site
Upon entering a Bloom-ravaged area, Wander will guide you to the first set of Bloom cankers and parasites. These are typically white infections taking over wildlife. Use your Sonic Resonator to destroy them. Your PDA will confirm when the treatment is successful.
Address the Infected Angel Comb
You'll likely encounter an infected angel comb. Wander will prompt you to save it. However, the angel comb often cannot be treated immediately. You must first track down other infection sites. Head north from the first location to find the second site.
Navigate the Second Infection Site
This location is often guarded by aggressive creatures like Nibbler Mango. Pack flares to distract them and avoid damage. Destroy the Bloom cankers here. Once cleared, your PDA will confirm success, allowing you to return to the infected angel core.
Confront the Final Armored Site
The third and final area is typically protected by a Marrowbreach. Again, flares are highly recommended for distraction. This area often contains four Bloom parasites that glow bright blue, making them easier to spot. Destroying these parasites will open the core, unlocking the Heat Tolerance adaptation, crucial for surviving hotter environments.
Remember that some cankers might appear permanently closed. This often means you need to clear other, smaller Bloom infections or progress further in the story before they become vulnerable. Always follow the Bloom branches and tentacles, as they often lead to hidden infection sites.
Strategy for Persistent Armored Cankers
If you encounter armored cankers that don't respond to the basic Sonic Resonator:
- Check for Feedback Resonator: Ensure you have the Feedback Resonator and its necessary mod.
- Maintain Distance: Some players report that the Feedback Resonator works best at a specific distance, just before the reticle turns green.
- Prioritize Open Cankers: Often, the armored cankers only open after all surrounding, unarmored Bloom infections have been destroyed. Scan closed cankers; they might reveal that they are feeding off nearby open ones.
- Explore Vertically: If a branch seems to lead to a dead end, consider looking up or down. Bloom infections can be hidden in wreckage or caves above or below the main path.
Open Cankers
- Destroy with Sonic Resonator
- Often found in early infection sites
- Easier to clear, directly visible
Armored Cankers
- Requires Feedback Resonator (Modded)
- May need specific distance and prior clearing of open cankers
- Often found in later, more challenging Bloom zones
Essential Gear and Tactics for Bloom Clearance
Successfully navigating Bloom-infected zones and destroying armored cankers requires not just the right tools, but also smart tactical choices.
Always carry extra flares when entering areas with aggressive fauna. They can be a lifesaver when dealing with creatures like Nibbler Mango or Marrowbreaches, allowing you to focus on Bloom destruction.
Inventory Checklist for Bloom Missions
Before heading into heavily infected areas, ensure you have these items:
Bloom Clearance Gear:
- Sonic Resonator (fully charged)
- Feedback Resonator (with mod, if available)
- Flares (at least 3-5)
- Basic Batteries (for recharging tools)
- Med Kits (for unexpected damage)
- Oxygen Tanks (extra capacity for deep dives)
Tactical Considerations
| Scenario | Recommended Tactic |
|---|---|
| Aggressive Fauna | Deploy flares to distract and create an escape window. |
| Closed Cankers | Scan them to understand dependencies; seek out open ones first. |
| Lost/Stuck | Re-trace Bloom branches, check for vertical paths. Wander's cues are vital. |
| Low Oxygen | Look for Bloom sap formations; destroying them often reveals oxygen pockets. |
Some players have reported issues where cankers remain permanently closed, even with the correct tools. This can sometimes be a bug, or it might indicate that a specific sequence of events or another hidden Bloom site needs to be addressed first. For instance, the "Last Angel Bloom" near the giant drill mechanism will only open its closed spore things after smaller blooms around it have been dealt with. The wreckage site is also a common place for hidden spores requiring the advanced resonator.
FAQ: Subnautica 2 Armored Pox
Q: What is an armored pox in Subnautica 2?
An armored pox refers to the closed or hardened Bloom cankers that cannot be destroyed by the basic Sonic Resonator. These often require an upgraded tool like the Feedback Resonator with a specific mod.
Q: How do I get the Sonic Resonator in Subnautica 2?
The Sonic Resonator blueprint is found near the Blackbox - Wander signal. You'll receive coordinates from Noa after discovering remains at the Blackbox - Ruby signal. Scan the discarded tool to learn the crafting recipe.
Q: Why can't I destroy some Bloom cankers with the Sonic Resonator?
Some Bloom cankers are armored or permanently closed until you clear other, often smaller, open Bloom infections in the vicinity. You might also need the Feedback Resonator mod for these tougher variants.
Q: Are there any bugs with the armored Bloom cankers?
While the game is designed for specific progression, some players have reported instances where cankers seem stuck or permanently closed. Ensure all other infection sites are cleared and you have the correct tool (Feedback Resonator with mod) and technique (distance for armored cankers) before considering it a bug.
