Chapter 9
Finale branches and multi‑phase bosses. Spoiler light.
Summary
Enter the Chronorift Citadel, stabilize fractured timelines, and confront the corrupted Chrono Sovereign before reality collapses. Recommended level: 28–30 with memory cap 30–32.
Branches & Choices
- Choose the Temporal Vanguard path for direct combat and faster boss access.
- Take the Anomaly Dive to secure true ending flags and rare chronal materials.
- Optional: Align all three Chronoseals to unlock the True Ending and disable the Sovereign’s rage loop.
Boss Strategy
- Weakness cycles: Phase 1 → Ice, Phase 2 → Fire, Phase 3 → Light (each +40%).
- Phase counters: cleanse Doom/Seal, guard against Rift Nova, burst during exposed windows.
- Speed target: 200 to preempt Chrono Sovereign’s opening Rift Pulse.
Collectibles Checklist
Prep Checklist
- Field at least one attacker for each weakness cycle (Ice, Fire, Light); recommended cores: Gabumon → MetalGarurumon, Agumon → WarGreymon, Patamon → Seraphimon.
- Equip Doom Ward+ and Seal Guard accessories to mitigate Chrono status spam.
- Carry 5 Chrono Cleanse items and 4 EX Power Charge for long boss phases.
- Install Memory Chips Omega+ and Sigma before entering; Chip Infinity can push you to 32 memory mid-chapter.
- Craft Phasebreak sigils using Sovereign Core Alloy + Quantum Capacitors to shatter shields quickly during phase transitions.
Route Breakdown
- Chronorift Gate. Meet Mirei at the Citadel threshold, receive Chronoseal tracker, and choose Vanguard vs. Anomaly routes.
- Temporal Vanguard Path. Fight elite Chrono Knights, stabilize Rift Anchors A/B, and earn +5 Strategist affinity for preventing collateral.
- Anomaly Dive. Traverse fragmented time shards, solve echo puzzles (Past → Future → Present), secure Chronoseal fragments, and rescue council echoes for Supporter affinity.
- Chronoseal Alignments (Optional). Align seals in three arenas (Solar, Lunar, Nexus) to disable the Sovereign rage loop and unlock the True Ending flag.
- Sanctum Core. Combine seal fragments, claim Memory Chip Infinity, and watch the pre-fight rally cutscene (affinity boost).
- Rift Gauntlet. Survive three waves of mixed-element bosses (Phantomon → MarineDevimon → Seraphiel) to unlock the inner chamber; Wind counters speed up clears.
- Boss: Chrono Sovereign. Three-phase battle with rotating weaknesses and shield resets; time your Phasebreak sigils to strip invulnerability and manage Doom timers.
- Aftermath. If all seals aligned, view the True Ending epilogue, gain Chrono Sovereign scan, unlock New Game+ modifiers, and receive the Farewell council scene.
