Chaos Zero Nightmare F2P Auto Tier List and Best Teams

To build an efficient free-to-play roster for auto-battles in Chaos Zero Nightmare, prioritize combatants who do not rely on strict card sequencing. The automated battle system plays cards based on fixed script weights rather than tactical board states, which causes combo-reliant carries to underperform. Investing in self-sufficient damage dealers, low-cost card cyclers, and passive healers ensures consistent clears for daily farming and roguelike runs.

Auto-Battle F2P Unit Tier List

The following combatants deliver reliable performance on auto-play due to low Action Point (AP) demands, predictable skill triggers, and compressed team roles.

Tier	Role	Combatant	Key Strengths in Auto Combat
S	Primary DPS	Mei Lin	Consistent multi-hit scaling and a straightforward skill cycle without complex combo setup.
S	Utility / Sub-DPS	Beryl	Low-cost deck cycling and strong passive skill triggers that fit almost any team lineup.
S	Sustain Support	Mika	Passive healing and debuff cleansing that prevent sudden wipes caused by poor AI card plays.
A	Burst Carry	Haru	High base multipliers that maintain solid clear speeds even when skill ordering is suboptimal.
A	Defensive Anchor	Adelheid	Steady damage mitigation and crowd control to stabilize the team during long battles.

Top Auto Performers vs. Manual Specialists

Mei Lin: Operates as the safest general investment for F2P players. Her deck features steady multi-hit damage that ramps naturally over extended fights without needing specific buff windows.
Beryl: Functions as an AP-efficient draw engine. She cycles cards rapidly to prevent dead hands while adding passive off-turn damage.
Mika: Serves as the primary defensive anchor. Her healing and cleansing trigger without requiring hand management, insulating the team from attrition.
Manual Specialists to Avoid on Auto: High-ceiling combatants dependent on combo-chaining mechanics (such as playing specific primers before finishers) drop significantly in value under AI control. Reserve strict combo units for manual challenge clears like high-tier Sorties or milestone bosses, and leave daily farming to passive, self-starting kits.

Best F2P Auto Team Compositions

Pairing self-sufficient carries with consistent support cards prevents your hand from clogging with unplayable high-cost actions.

1. Balanced General Farming Core

Primary DPS: Mei Lin
Sub-DPS / Deck Engine: Beryl
Sustain Support: Mika

This setup handles standard resource stages and daily grinding on full auto. Beryl generates card cycle and feeds turn actions directly to Mei Lin, who handles both single-target and multi-target damage. Mika automatically absorbs and cleanses incoming chip damage, removing the need to time defensive cards manually.

2. High-Difficulty Attrition Core

Primary DPS: Haru
Tank / Control: Adelheid
Sustain Support: Mika

For tougher progression stages where burst damage threatens your frontline, swap in Adelheid. Haru provides raw damage output that punches through heavier health pools without complex setup. Adelheid and Mika stack damage reduction, control effects, and continuous recovery, resulting in slower clear times but a much higher completion rate against hard-hitting enemy formations.

Pre-Anniversary Investment Strategy

Leading into an anniversary update, avoid spreading upgrade materials across speculative or niche combatants.Meta shifts and limited banners frequently introduce high-tier options that can disrupt standard rankings.

Limit your immediate focus to a single core team: Maximize the skill levels and primary stat gear on your main damage dealer (such as Mei Lin or Haru) before investing in secondary units.
Secure daily farm consistency: Once your three-to-four unit core completes routine farming runs without failure, stop spending resources on side-grade characters.
Hoard summon currency: Bank all premium currency and summon tickets for upcoming anniversary banners or character selectors rather than pulling on standard banners.
