What Are Angel Combs?
Angel Combs are glowing purple plants scattered across Proteus. Interacting with them unlocks Adaptations, permanent character upgrades that give you new abilities. They are the core progression system in Subnautica 2, gating access to biomes, resources, and story content.
All Adaptations, in Order
1. Digestion (Must Get First)
| Detail | Info | |--------|------| | Location | Northeast of Lifepod, ~160m | | Depth | Shallow (15-30m) | | Prerequisite | None |
What it does: Lets you safely eat local fish and plants. Without Digestion, consuming alien food causes sickness and health loss. This is the #1 early-game mistake, new players starve because they didn't get this first.
How to find: From your Lifepod, swim northeast. Look for a glowing purple plant on the seabed. Interact with it.
2. Endurance (More Inventory)
| Detail | Info | |--------|------| | Location | Multiple: Sophie's Retreat + Cicada Wreck + Unauthorized NOA Mod | | Depth | 30-80m | | Prerequisite | Digestion |
What it does: Adds extra inventory slots and quickbar slots. More carrying capacity = fewer trips back to base.
3. Dexterity (Better Tool Handling)
| Detail | Info | |--------|------| | Location | Nahema's Lab, Hydrothermal Vents | | Depth | 50-150m | | Prerequisite | Digestion, Sonic Resonator |
What it does: Improves tool handling speed and efficiency.
Note: The Hydrothermal Vents are hot, you'll take damage without Heat Tolerance. Get in, interact with the Angel Comb, and get out quickly if you don't have Heat Tolerance yet.
4. Heat Tolerance (Access Hot Biomes)
| Detail | Info | |--------|------| | Location | Blighted Area Angel Comb | | Depth | 20-40m | | Prerequisite | Sonic Resonator (to clear Bloom Cankers blocking the area) |
What it does: Lets you survive in hot biomes, Hydrothermal Vents, Hot Caves, and certain deep Karakorum areas. Without it, hot water damages you rapidly.
How to find: The Blighted Area is east of the Old Habitat. You'll need the Sonic Resonator to clear Bloated Bloom Cankers blocking your path.
5. Axum Vision (Late Game, Story Critical)
| Detail | Info | |--------|------| | Location | Karakorum Power Plant | | Depth | 200m+ | | Prerequisite | Heat Tolerance, Tadpole with Depth Module, access to Karakorum |
What it does: Required to repair the Power Plant and progress the main story. This is the last adaptation in the current Early Access build.

Frequently Missed Adaptations
- Digestion can be missed entirely if you don't explore northeast. You'll wonder why you keep getting sick from eating fish.
- Heat Tolerance requires the Sonic Resonator. You can't clear the Bloom Cankers blocking the Blighted Area without it. Get the Sonic Resonator from Old Habitat fragments first.
- Dexterity is in a hot zone. You'll need to tank some heat damage if you go for it before Heat Tolerance. Bring medkits.
