This page is the BRIGANDINE ABYSS classes hub: how Leader and Monster classes interact with squads, then where to go for progression (Class Change) and unit picks (Monsters, Best Monsters).

If a promotion still leaves your roster behind, compare the practical catch-up loop in Difficulty, enemy levels, and Training Ground advice, then use Quests & Exploration for reserve planning and Stronghold Upgrades for gear, recruitment, and base decisions.

  • Both leaders and monsters can change class (NIS system).
  • Commonly reported milestones occur at level 10 and level 20 (currently reported by RPGamer).
  • Promotions can increase a unit’s Command Point cost (reported).
  • Some later class branches may require quest class-change items.
  • Class reversal is not yet reliably verified.

Promotions can change a unit’s statistics and role. Reporting indicates monster promotions have sometimes increased a monster’s Command Point cost. Because squads are limited (up to five monsters) and formation is determined by the leader, any increase in a monster’s Command Point cost can affect how many and which units you can field together. Treat Command Point changes as an important consideration when promoting units.

  1. Confirm whether the unit is a leader or a monster — both can change class, but leaders also set formation.
  2. Check milestone levels: level 10 and level 20 are reported promotion points; verify in your playthrough.
  3. Watch for item requirements: some later branch promotions may need quest class-change items.
  4. Expect possible Command Point increases after promotion; plan squad composition accordingly.
  5. Remember class reversibility has not been reliably verified—assume promotions may be permanent unless you find a confirmed reversal method.
SituationPractical guidance
You reach level 10Consider the reported level 10 milestone as a natural point to evaluate a class change; review the unit’s role and potential CP impact.
You reach level 20Treat level 20 as a second major milestone; check for any item requirements before attempting later branches.
Leader promotionBecause leaders determine formation, plan how a leader’s new class will affect your squad layout and which monsters will fit.
Monster promotion raises CP costRe-evaluate squad composition and Command Point budget; you may need to swap or delay other promotions.
Unsure about reversibility or rare branchesDelay irreversible choices until you confirm reversibility through gameplay or an official guide; consult the game’s item/quest lists.

Q: What are the confirmed level milestones for class changes?

A: Level 10 and level 20 are commonly reported milestones (RPGamer review). These are current reports and may not cover every branch.

Q: Do both leaders and monsters change class?

A: Yes. The game’s NIS system allows class changes for both leaders and monsters; squads include up to five monsters and formation is determined by the leader.

Q: Will I need items to access class branches?

A: Some later branches may require quest class-change items according to reporting and the system’s wording. Early milestone changes are described without that caveat.

Q: Can class changes increase my squad’s Command Point cost?

A: Yes. Monster promotions have been reported to sometimes raise their Command Point cost (RPGamer review), which affects squad composition.

Q: Can I revert a class change?

A: Not yet reliably verified. Treat reversibility as uncertain until confirmed.
