Chaos Zero Nightmare Hidden Character Passives Explained
Chaos Zero Nightmare hides a lot of power in implicit passives and keywords that are not spelled out on basic tooltips: things like Futility scaling, Decibel shuffle damage, Mark targeting, and Inspiration triggers. Understanding these “hidden” behaviors lets you build decks and teams that exploit mechanics other players barely notice.

Keyword-Style Hidden Passives on Characters
Several characters have signature mechanics that act like hidden passives.
- Kayron – Futility / Exhaust scaling DPS
- Kayron uses the Futility keyword: ostensibly “dead” cards that do nothing but fill the exhaust pile, then his skills deal damage based on how many cards have been exhausted.
- Hidden effect: every Futility/exhaust card you cycle is effectively future damage; his passive scaling rewards heavy deck cycling and discard.
- Nia – Decibel shuffle damage
- Selena – Mark targeting
These mechanics often sit in small text or not at all on the main card, but they define how you should build and pilot each character.
Inspiration, Draw, and “When Drawn” Effects
Inspiration is one of the most important hidden-style systems.
- Inspiration basics:
- Hidden implication:
- Inspiration builds (Yuki, Veronica, others) scale with how often and how many cards they draw, so any passive that increases draw count or reshuffles your deck is effectively a hidden damage/heal engine.
Decks that spam draw or reshuffle multiple times per turn exploit this mechanic far better than just stacking raw attack.
Dupes, Potential, and Upgraded Base Cards
Some “passives” only show up when you invest dupes and Potential.
- Duplicate-based upgrades:
- A long-form impressions post notes that certain characters gain additional keywords when cards are duplicated, like a card gaining Retain at dupe 2 vs having no Retain at dupe 0.
- Hidden effect: an otherwise mediocre card can become core once it starts retaining, discarding, or applying a new keyword at higher manifestations.
- Potential nodes:
- Each character has unique Potential nodes that buff basic cards (heals, shields, damage) by percentages and sometimes add special behavior.
- Hidden effect: a character’s “vanilla” heal or block can become significantly stronger or gain extra effects after you invest Potential, changing how valuable that card is in your deck.
Because of this, late-game builds often reevaluate characters once more dupes and Potential nodes are unlocked.
Partner Passives that Look Small but Aren’t
Partner passives are another layer of hidden power; many are multipliers on specific card types rather than flat stats.
- Examples from partner guides:
- Extra attack partners: give 10–20% multiplicative bonus to extra attack damage, scaling higher with manifestations.
- Bullet partners (e.g., Akad): give 10–20% unconditional bullet damage, then another 12–24% after a crit, and this bonus also applies to the extra‑attack portion of dirge bullets.
- Low-cost card partners: grant additional 10–20% damage for cards that cost 1 AP or less, plus stacking damage when you use skill cards.
- Defensive/healing partners: give 12–24% bonus Defense (which healing scales from), plus 3–6% HP recovery at end of battle, or start-of-turn damage reduction stacks based on enemies planning to attack.
None of these radically change input, but they heavily tilt math in favor of certain archetypes (Hugo follow-ups, Renoa bullets, 0‑cost spam, Mika/Nia healing shells).
How to Exploit Hidden Passives in Practice
- Read keywords and passives carefully:
- Build decks around triggers, not just stats:
- Respect dupe and Potential breakpoints:
Once you understand these hidden passives, Chaos Zero Nightmare stops being just “play your highest-cost attacks” and becomes a game of engineering triggers and multipliers, turning subtle mechanics like Futility, Decibel, Inspiration, and partner passives into your real damage and control engines.
