Chaos Key Quests and Terminus Progression Guide
Complete Chaos Key quest chain in Endless Ragnarok: Count One through Beyond the Terminus, Sundappled Grove, Earthchurner Ragnalia, and Maniac unlock order.
What Are Chaos Key Quests?
Chaos Key quests are a Folca and Seedhollow quest line that gates deeper expansion story beats, Maniac difficulty access, and Proud-tier farming for Ultimate Memory. They sit alongside the 11 optional Chaos side quests but drive main progression rather than sticker or card rewards.
You need Chaos difficulty unlocked first via A Trial of Two Eternities. Complete Conflux Cycle 3 and expansion story prerequisites before the Count series appears in Folca.
Terminus Progression Quest Chain
| Quest | Location | Unlocks / Purpose |
|---|---|---|
| Count One | Folca | Starts Terminus weapon goal chain; gates Maniac access steps |
| Count Two | Folca | Mid-chain progression toward Proud weapon goals |
| Count Three: Last Stop | Folca | Unlocks side quest TKO and deeper Folca content |
| Beyond the Terminus | Folca | Capstone Terminus quest; unlocks Proud-tier weapon farming goals |
Clear each quest in order. Higher Chaos tiers (Chaos+, Chaos++) unlock additional Folca side content documented on our side quests page. Pair the Count chain with rank-ups on the Fatebreaker guide route.
Sundappled Grove and Earthchurner Ragnalia
After Chaos unlock, investigate Sundappled Grove and defeat Earthchurner Ragnalia to advance expansion narrative gates tied to the Chaos Key thread. This boss encounter sits between Conflux Cycle 3 completion and deeper story beats referenced in our walkthrough.
Ragnalia fights use Chaos mechanics including EX Burst windows. Bring Fatebreaker-grade gear, a equipped Fatebreaker sigil, and Summon gauge planning—see Chaos difficulty guide for survival tips.

Frequently Asked Questions
Are Chaos Key quests the same as Chaos side quests?
No. Side quests are optional Folca and Seedhollow missions for stickers and cards. Chaos Key quests are the Count One through Beyond the Terminus chain gating Maniac and Proud progression.
When does Sundappled Grove unlock?
After Chaos difficulty and mid-expansion story progress—typically after Conflux Cycle 3 and initial Folca Terminus quests.
Do I need Beyond the Terminus for Ultimate Memory?
Not directly, but Proud-tier access from the chain makes Bahamut's Rage (Proud) farming much faster than lower difficulties.
