Tier Explanations

SS Tier — Top Meta Picks

Mei Lin

Mei Lin continues to be the strongest single-target DPS for Passion-oriented teams. Her ability to apply Passion weakness consistently and generate AP through Tenacity damage gives her unmatched stability. She’s future-proof thanks to her dual role as a buffer and primary damage dealer.

Mika

A pure F2P healer with incredible AP generation, Mika fits into nearly any lineup. Her straightforward card flow and reliable sustain make her one of the most universal supports available.

Veronica

Veronica excels as a sub-DPS that summons Ballistas dealing passive damage every turn. She also enhances team synergy with card draw effects, making her a powerful engine for many offensive setups.

Khalipe

Known for high AoE output and strong defensive utility, Khalipe adapts well to multiple teams. Her kit combines easy setup with Tenacity-breaking potential, allowing flexible and impactful turns.

S Tier — Strong, Reliable Choices

Haru

Haru specializes in explosive burst rotations through repeated Anchor Shot usage. She thrives in decks that provide extra cards, enabling her to stack big turns quickly.

Hugo

A follow-up attacker who shines in single-target encounters. Although he struggles with AoE-heavy units, his synergy-based kit lets him operate as a sub-DPS or even a main DPS with proper support.

Kayron

Kayron is one of the most flexible Combatants thanks to scaling Exhaust mechanics. He offers excellent AoE damage and fits into a large variety of team cores.

Tressa

An F2P DoT-focused DPS, Tressa spreads damage across the board while benefiting from 0-cost Shadow Daggers. She supports follow-up teams exceptionally well.

Rei

Rei provides consistent buffs, deck thinning, and Morale scaling. Her support makes multi-hit-oriented teams perform much better.

Cassius

The premier utility unit for card cycling. He can draw, shuffle, buff, debuff, and heal while maintaining tempo through his quest mechanic, making him one of the most complete supports.

A Tier — Effective but More Setup-Heavy

Selena

A flexible DPS who applies Mark and Passion weakness while assisting with Tenacity breaks. Works best in Passion-based squads.

Beryl

Focused on high-impact burst windows, Beryl retains her strongest cards for huge damage or reduced AP cost. Great for players who enjoy timing powerful attacks.

Rin

A selfish, consistent single-target DPS. She shines as a solo damage dealer but loses tempo when sharing attack windows with other units.

Yuki

Yuki deals steady AoE damage through Inspiration-tagged cards. However, she relies heavily on card draw and can collapse if placed in the wrong lineup.

Renoa

A bullet-based DPS that excels at follow-up hits. She needs discard or search support because her bullets can clutter the deck without proper management.

Magna

A counterattacking tank that scales damage through defense. Magna is easy to slot into many teams, adding survivability and extra DPS.

B Tier — Niche or High-Effort Picks

Luke

A single-target bullet DPS with RNG-dependent critical mechanics. Requires high crit investment to perform optimally.

Orlea

A sustain-focused support who uses Retain mechanics to maintain steady damage and healing. She grows stronger during long encounters.

Nia

Provides card manipulation, light healing, and easy-to-trigger follow-up attacks. Works particularly well with high-damage units needing discard tools.

Maribell

A tank that scales shield usage into offensive output. Reliable, but outperformed by more modern defensive picks.

Owen

A F2P DPS option for beginners. Easy to build and straightforward, but lacks the scaling and ceiling found in stronger units.

C Tier — Usable but Not Recommended Long-Term

Lucas

An AoE bullet user with Mark and Passion weakness synergy. However, his AP requirements make him difficult to justify over stronger alternatives.

Amir

A defensive tank whose Metallization scaling falls behind. She struggles to fit into most comps due to low defensive numbers and weak damage output.

Tier List Criteria

This Chaos Zero Nightmare tier list evaluates characters using three core factors:

1. Damage Potential

How much output a character can generate without relying heavily on specific teammates.

2. Utility

Covers healing, shielding, buffs, debuffs, and any mechanic that increases team survival or performance.

3. Ease of Use

How consistent and simple their card setup is no convoluted conditions, minimal RNG, and solid turn flow.

Tier Scoring Overview

• SS Rank – Best-in-class picks that excel in any team.
• S Rank – Easy to use, strong in most situations.
• A Rank – Great in the right comps, but require setup.
• B Rank – Only strong in specific synergies or with high effort.
