Chaos Zero Nightmare Debuff and Support Builds That Carry Teams
Chaos Zero Nightmare’s strongest teams are often anchored by debuff and support builds that multiply everyone else’s damage while keeping runs safe and consistent. Units like Mika, Rei, Selena, and Tressa enable Exhaust, follow‑up, and Bullet strategies that routinely outperform raw DPS stacks in real content.
Core Debuffs and Buffs
Understanding which status effects scale multiplicatively is what turns a good support into a carry in high‑difficulty content.
- Weaken and Vulnerable are multiplicative damage modifiers, meaning they boost final damage rather than just attack, which is why debuffers that apply them are so highly valued.
- Morale, Fortitude, and shield‑boosting buffs dramatically increase survivability, while Immunity and cleanse effects prevent lethal debuff stacks in Chaos and Nightmare stages.
S-Tier Debuff and Support Units
These supports are consistently rated top tier because they combine AP, card flow, and premium debuffs in one package.
| Role | Key unit | What they do | External reference |
|---|---|---|---|
| Healer / AP battery | Mika | Top‑tier sustain plus AP recovery, making almost any team more stable and explosive; widely regarded as near‑universal support. | OSLink Tier List |
| Exhaust / futility support | Rei | Low‑cost buffs, Exhaust application, and deck smoothing that turbocharges Exhaust and Bullet comps. | LootBar Team Guide |
| Free support / sub‑DPS | Tressa | Free unit with strong chip damage and support value that shines in Exhaust and follow‑up setups. | OSLink Tier List |
| Offensive debuffer | Selena | Passion support that layers offensive buffs, marks, and debuffs, especially when paired with Mei Lin. | Game8 Character Tier List |
| Deck / retain support | Cassius / Nia | Hand‑fixers and retain supports that prevent bricked turns in boss and Chaos content. | Game8 Best Teams notes |
Sample Debuff/Support-Centric Teams
These team shells show how supports become the real win condition once mechanics are mastered.
| Team concept | Core trio | How it carries | External reference |
|---|---|---|---|
| Exhaust lockdown | Kayron + Rei/Tressa + Mika | Rei/Tressa feed Exhaust and curses while Mika keeps AP and HP flowing; bosses melt over time even with modest DPS stats. | LootBar – Exhaust Teams |
| Follow-up spam | Hugo + Tressa/Selena + Nia | Supports stack Hunt/follow‑ups and ensure smooth draws, turning Hugo into a constant extra‑attack engine. | LootBar – Follow-Up Teams |
| Safe boss control | Mei Lin + Mika + Cassius | Mei Lin breaks and bursts, Mika sustains, Cassius fixes bad hands; recommended as a “best for beginners” boss squad. | LDCloud Team Guide |
| Bullet / DoT ramp | Renoa/Luke + Rei + Mika | Rei and Mika enable constant card spam so Bullet checks and DoT stacks ramp to absurd levels in long fights. | LDShop Bullet Teams |
Build Priorities for Supports
Support builds focus less on raw attack and more on uptime, survivability, and consistent debuff application.
- Prioritize AP generation, draw, and cost‑reduction effects on supports like Mika, Rei, Cassius, and Nia to maximize how many key debuff cards you can play each turn.
- Stack HP, defense, Fortitude, and shield‑boosting effects on pure supports so they stay alive long enough to maintain Vulnerable, Weaken, Exhaust, and other multiplicative modifiers on bosses.
