Elysia Oasis Decisive BattleFirst Sector Finale
The Elysia Oasis Decisive Battle is the finale of Elysia, and the most officially adjusted battle in Pax Autocratica's history — between June and July 2026, Multiverse shipped six balance patches for it. This file compiles every verifiable detail from the official patch notes.
Battle Structure
Per the official patch notes, the battle uses a multi-phase structure:
- Regular engagement phase — you advance alongside allied forces (the 2026-07-07 patch converted the support units into allies)
- Position assault — the enemy deploys turret emplacements (their positions were officially rearranged twice, on July 23 and 28)
- Final phase — enemies reinforce in waves while the Fortress Bunker takes the field — a giant fortress mounted on mechanical legs
Core Mechanic: The Mechanical Leg Weak Point
This is the only strategy point officially documented in the patch notes:
The standard playbook this confirms:
- The core objective of the final phase is the Fortress Bunker's Mechanical Leg Weak Point — focus fire on it instead of dumping damage into the main body
- The game provides guidance prompts (strengthened by the July 22 patch) — follow the UI cues
- Hitting the weak point triggers a heavy-hit reaction — use it as your confirmation signal and keep firing
- EMP-type tools can disable elite and boss shields (see Core Fragments), opening windows for weak-point strikes
Complete Official Adjustment Record
First Difficulty Reduction
The battle's overall difficulty was reduced for the first time.
Second Difficulty Reduction · Allied Forces Adjustment
Difficulty reduced again; support units converted into allied forces.
Weak Point Guidance Strengthened
Improved the guidance for the Fortress Bunker's Mechanical Leg Weak Point; added heavy-hit reactions to enemy weak points.
Turret Position Adjustment (I)
Enemy turret positions rearranged.
Third Difficulty Reduction · Turret Position Adjustment (II)
Difficulty reduced for the third time; turret positions adjusted again.
Final-Phase Pacing Tune
Adjusted the spawn count and intervals of final-phase enemies.
If Oasis broke you in an earlier version: the current battle has been through three difficulty reductions and one pacing tune — far more forgiving than at launch. Bring your best core build, keep your eyes on the mechanical legs — the State awaits your victory report.
Pre-Battle Checklist
- Finish your core build — stack Core Fragments around a single archetype through the first half of the expedition so your weapon form is fully realized before the battle
- Field full-strength troops — the battle is a large-scale melee; firepower from allies and your own units is critical
- Mobility first — keep moving through the wave brawls; use the double jump and jetpack to stay out of dense bullet zones
- Ammo and condition — confirm your gear and supplies are fully stocked by the colony production lines before departure
