Promotion Mission & Growth Guide
Beyond regular Story and Battle Missions, Chaos Zero Nightmare also has the Growth Guide — an account-progress mission system capped off by a Promotion Mission in each chapter. This page summarizes the mechanic and the confirmed level milestones.
The Growth Guide is an account-progress mission system (a book icon in the same menu as dailies and achievements), tied to your roster's Character Affinity. Each chapter has its own set of Growth Guide missions — for example, Chapter 1 has exactly 8: 7 regular missions and 1 special one called the Promotion Mission. You need to finish the chapter's Story and Battle Missions plus all 7 regular Growth Guide missions, and reach the required level, before the Promotion Mission appears; completing it uncaps your Captain Level and unlocks the next chapter.
The 3 mission types in Story Mode
3 confirmed Promotion Mission milestones
| Captain Level | Unlocks |

| Lv20 | Unlocks the Weekly Boss. |

| Lv40 | Unlocks the Memory Fragments feature (combatant equipment). |
Promotion Mission by chapter
Each chapter has its own story boss; clearing that chapter's Promotion Mission grants a new Captain rank and raises the level cap. Chapters 1-3 now have a confirmed boss, weakness attribute and recommended level; Chapters 4-5 have a confirmed rank/new cap/unlock, but their story boss hasn't been announced yet.

Only the RULES are covered here (what to dodge, what threshold triggers what) — no HP, EXP or Crystal reward numbers.
Story Mission rewards
Completing Story Missions grants several resource types as a FIXED amount per chapter (not random) — the source we have to cross-check exact figures is fairly old, so we're not printing specific numbers here, only the reward types; see the mechanics of each on the Items page.
The Growth Guide/Promotion Mission mechanic is compiled from community guide notes, cross-checked for Captain Level 20/30/40 (their unlocks are confirmed). The story boss, weakness attribute, recommended level, Promotion rank and unlock for all 5 chapters have been cross-checked against a source whose content was readable; only the Chapters 4-5 story boss hasn't been announced by the source, and this page does not speculate further.

Frequently Asked Questions about Missions
Story and Battle Missions advance the chapter's plot; the Promotion Mission is a SEPARATE mission that only appears once your account has met that chapter's full requirements (including all 7 regular Growth Guide missions) — completing it is what uncaps your Captain Level and unlocks the next chapter.
Level 20. After completing the Promotion Mission at the Level 20 milestone, the Weekly Boss unlocks.
Exactly 8: 7 regular missions and 1 Promotion Mission. The Promotion Mission only appears after the 7 regular missions (plus the chapter's Story/Battle missions and reaching the required level) are complete.
The recommended level is what you SHOULD reach before attempting that chapter's boss (e.g. Level 20 before facing Bercula in Chapter 2). The new level cap is what gets UNLOCKED after clearing that chapter's Promotion Mission (e.g. clearing Chapter 2 raises the cap to Level 30) — the two numbers apply at different points in the chapter's progression.
