Chapter 3 — Foundry Core
Monolith Engine Boss Guide
Pragmata Monolith Engine boss fight strategy — every attack pattern, the safest counter, and the rewards you'll walk away with.
Attack patterns
Monolith Engine cycles through 2 core attacks. Read the tell, counter cleanly, and don't rush the punish.
| Attack | Tell | Counter |
|---|---|---|
| Magma Geyser | Floor cracks turn orange | Sprint perpendicular — never linear |
| Conveyor Crush | Belt reverses | Jetpack to upper rail |
Strategy
- Solve all three lunar puzzles before damaging the reactor — otherwise final phase is uncapped.
- Bring high-stagger ammo: Monolith staggers at 35% threshold.
Recommended loadout
Bring the Stagger Cannon as your primary, plus the EMP Launcher if Monolith Engine has any phase or drone mechanic. Spend your lunafilament on the priorities listed in the upgrade route before this fight.
