Chapter 4 — Subterranean
Abyss Walker Boss Guide
Pragmata Abyss Walker boss fight strategy — every attack pattern, the safest counter, and the rewards you'll walk away with.
Attack patterns
Abyss Walker cycles through 2 core attacks. Read the tell, counter cleanly, and don't rush the punish.
| Attack | Tell | Counter |
|---|---|---|
| Phase Lunge | Body becomes translucent | Diana's reveal hack pins it for 2s |
| Sonar Scream | Stands still and roars | Crouch behind reinforced cover |
Strategy
- Use the EMP grenade dropped earlier in the chapter — it cancels phase shifts entirely.
Recommended loadout
Bring the Stagger Cannon as your primary, plus the EMP Launcher if Abyss Walker has any phase or drone mechanic. Spend your lunafilament on the priorities listed in the upgrade route before this fight.
After the fight
Pick up the REM data — feed it to Diana for the gift effect. Continue with the main walkthrough.
