What to know
- Cleansing Ability, or Cleanse, destroys red Dead Filament crystals blocking paths and corrupts enemies.
- Unlocked automatically in Sector 5 after defeating the Luna Digger boss in Sector 4.
- Use by charging an area-of-effect pulse; also clears blue Filament Masses indirectly via prior Lim Eraser.
- Essential for 100% collectibles like Safe Boxes and Storage Expanders in prior sectors.
Pragmata features obstructive crystal formations that block key paths and loot from early in the game. The Cleansing Ability empowers Diana to remove the tougher red variants, known as Dead Filament, opening up backtrack opportunities across multiple sectors.

Step-by-step unlock process
Follow the main story path without deviation, as the ability integrates automatically.
Step 1
Complete Sector 1: Solar Power Plants and enter Sector 2.
Step 2
In Sector 2: Mass Production Array, deactivate beacons up to the Business District rooftop.
Step 3
Descend into Lim Recycling Facility, clear enemies, collect Decoy Launcher, and interact with the lab terminal for Lim Eraser.
Step 4
Finish Sector 2, proceed through Sector 3: Terra Dome, and reach Sector 4: Lunum Mines.
Step 5
Defeat the Luna Digger boss at the end of Lunum Mines.
Step 6
Enter and complete the short Sector 5: Experimental Pragmatics chapter; Cleanse unlocks via cutscene upon fixing Diana.
How to use the Cleansing Ability
Position Hugh facing the red Dead Filament cluster. Hold LB (Xbox), L1 (PS), or E (PC) to charge—the ground ring expands to show blast radius. Release when it engulfs the crystals for detonation. No resources needed; repeat freely. In combat, target groups of corrupted enemies (showing red crystals) to remove slowdown effects and enable easier hacking.
Step 1
Approach red crystals directly.
Step 2
Hold charge button; watch expanding ring.
Step 3
Release over cluster to destroy.
Key locations blocked by Dead Filament
Dead Filament appears from Sector 3 onward, gating high-value items. Note these for post-unlock visits: Sector 2 Business District side alley yields two Safe Boxes near Red Zone after Escape Hatch; Sector 3 Terra Dome Eco Modeling Lab hides Safe Boxes off the atrium ledge; Sector 4 Lunum Mines Mine Entrance offers Storage Expander and Safe Boxes behind crystals right of Luna Digger repel area; Main Excavation Site under Logistics Hatch has more Safe Boxes.
Rewards from cleansing blocked areas
Clearing these yields critical upgrades for full completion.
| Location | Rewards |
|---|---|
| Sector 1 Generator Entrance | Storage Expander (hacking gauge upgrade) |
| Sector 2 Business District | Safe Box x2, Pure Lunum |
| Sector 3 Terra Dome Eco Lab | Safe Box x2 |
| Sector 4 Lunum Mines Entrance | Storage Expander, Safe Box x3 |
| Sector 4 Main Excavation | Safe Box x1+ |
Tips for efficient backtracking
Return systematically to avoid missing items.
Step 1
Solar Power Plants: Clear Generator Entrance corridor for Storage Expander.
Step 2
Mass Production Array: Business District lower areas for Safe Boxes.
Step 3
Terra Dome: Envirolytics and Eco Modeling Labs for remaining boxes.
Step 4
Lunum Mines: Entrance and Excavation Site for expanders and Lunum.
Beyond walls, cleanse adds combat utility—remove red crystals from foes to halt hacking interference. Charge in tight enemy packs for multi-cleanses. Combine with Lim Eraser for all barriers; no overlaps exist between the two.
