Tier Classification

We adopt a tier classification system to intuitively present the comprehensive performance of characters in the game's highest difficulty scenarios. Note that this tier list covers two primary modes: Seasonal Save Data (covering Nebula Distortion, Full-scale Offensive, Tower of Screams, and other save-based modes) and Chaos Manifestation (the roguelike gameplay). Characters may perform differently across these modes.

S Tier: Exceptional consistency, flexibility, and power. These characters can carry teams through the highest difficulty content without relying on specific Epiphanies, equipment luck, or favorable hand states.

A Tier: Extremely strong and capable of clearing all high-end content, falling just short of S due to slightly weaker starting conditions, reliance on certain Epiphanies or equipment, or lower total damage/utility ceiling.

B Tier: Solid characters that can clear high-difficulty challenges but are less powerful or consistent than S/A characters. They may rely more on specific build paths to reach their full potential.

C Tier: Viable but noticeably outclassed in one or multiple areas. Can fill a role but generally surpassed by higher-tier options for the same function.

DPS Tier List

The main focus of these characters is to maximize the damage they deal and serve as the primary damage source in the team.

Seasonal Save Data

Chaos Manifestation

S Recommended Character: Heidemarie

Heidemarie is the half-anniversary limited 5-Star Passion Ranger whose combat style revolves around generating and discarding Effulgent Blades to trigger burst damage. Her core mechanic is the [Linked] tag: when any [Linked] card is played manually, all other [Linked] cards in hand are automatically discarded — including her generated Effulgent Blades, which deal extra damage on discard. This allows her to unleash large chains of attacks while spending minimal AP. Her other key resource is Effulgent Light, accumulated by discarding her Mythic card Effulgent Compression three times, transforming it into Effulgent Release — a powerful 0-cost nuke whose damage scales with Effulgent Blades played.

Analysis: Heidemarie is the top-priority pull target in the current version. Her standalone damage is already exceptional, but her unique synergy with Hugo and Selena via Sword Rain III — which activates 5 Effulgent Blades in the discard pile, each count as extra attacks for both Hugo's "Commence The Hunt" and Selena's Coordinated Attacks — pushes her damage output to stand alongside Sereniel at the very top of the meta. She lands S in both Seasonal Save and Chaos Manifestation.

A Recommended Character: Diana

Diana is a discard-focused DPS who operates with very low AP commitment. Her damage output is solid even without extensive card-damage buffs, and she works well out of the box with her base deck. She benefits strongly from discard outlets that trigger her [Quietus] cards.

Analysis: Diana joins the meta as a strong and comfortable DPS option. She has a high damage ceiling and avoids the hard-block mechanics like Elasticity that limit characters such as Mei Lin. Nia is considered her signature support, and together they form a reliable discard-oriented team. Placed at A in both Save and Chaos.

A Tier Recommended Character: Mei Lin

Mei Lin is a combo-focused character. Her core strategy is to apply Weakness and gain Embers to increase subsequent damage. If players can manage their cards properly, her deck can recall the first basic attack through specific cards to achieve near-infinite combos, and these basic attacks can become zero-cost cards after Epiphany.

Analysis: Mei Lin is one of the top priority pull targets among all damage dealers and is considered the cheapest 5-star character due to her highly versatile skills, which perform excellently during progression and leveling.

A Tier Recommended Character: Hugo

Hugo relies on the "Hunt Stack" mechanic. Each card he plays generates Hunt Stack layers. When he has Hunt Stack layers and an ally launches an attack, Hugo will perform a follow-up attack, consuming one stack per follow-up. His core strategy is upgrade-based, and he ensures he can execute his game plan the same way every time through his starting card Initiation.

 Analysis: Hugo's advantage lies in the free or passive nature of his damage, as his follow-up attacks are triggered by allies. This makes him highly consistent in Chaos Mode, able to execute tactics efficiently even without relying on specific hand cards.

B Tier Recommended Character: Renoa

Renoa revolves around the Durge Bullet mechanic. Durge Bullets can be used to deal damage or ignored in the hand depending on the chosen strategy. If players plan to actively use Durge Bullets, she usually requires AP support characters like Rei and Mika to maintain frequent card plays.

Analysis: While Renoa can become extremely powerful after obtaining the correct Epiphany, capable of absolutely destroying the latter half of battles, her effectiveness may be poor without the right cards. She needs key cards and card management to optimize her damage potential.

S - DPS Tier List

These characters can be used as main DPS while also possessing excellent support capabilities. Their ratings are highly influenced by their ability to provide synergies and buffs to other characters.

Seasonal Save Data

Chaos Manifestation

S Tier Recommended Character: Hugo

Hugo relies on the "Hunt Stack" mechanic — each card played by his allies generates Hunt Stacks, and when stacked, he executes follow-up attacks that consume one stack per trigger. His core strategy is upgrade-based, and he ensures he can execute his game plan consistently every run through his starting card Initiation.

Analysis: Hugo has risen to S in Seasonal Save following the half-anniversary update. His new signature synergy with Heidemarie is transformative: Heidemarie's Sword Rain III activates 5 Effulgent Blades as extra attacks, and each one independently triggers Hugo's "Commence The Hunt," stacking his follow-up attacks to an absurd degree. He was already on the cusp of S and now firmly belongs at the top.

S Tier Recommended Character: Selena

Selena focuses on the Mark effect and Tenacity, enhancing the team's attack effectiveness by boosting attacks against marked enemies and enabling Coordinated/Extra Attacks on marked targets.

Analysis: Selena has shed the [Partner] tag she previously carried, as she is now a signature sub-DPS for both of CZN's limited characters — Sereniel and Heidemarie — demonstrating she is broadly viable across multiple team compositions rather than restricted to one. She remains S in Save.

S Tier Recommended Character: Veronica

Veronica has the best card-draw ability in the game, with many draws costing 0 AP. Her deck is oriented around upgrades, making her the ultimate deck thinner, able to consistently draw key combo pieces every turn. In Chaos mode, she also contributes meaningful passive damage via card reloads.

Analysis: In Save Data, Veronica is now primarily used in a full-support role due to her incredible draw and AP generation through Divine Epiphanies, and she is categorized there as Support. However, in Chaos, she doubles as a Support DPS, generating heaps of passive unconditional damage while supplying draw effects, placing her S in that mode.

A Tier Recommended Character: Tressa

 Tressa's best deck is also upgrade-based, exhausting cards and generating Shadow Daggers, which also apply Agony.

Analysis: Tressa's strategy is similar to Hugo's, with extremely high consistency, and she only requires any healing source to function. Her synergy with Hugo is very strong, as the dagger attacks she generates can trigger Hugo's follow-up attacks.

A Tier Recommended Character: Selena

 Selena focuses on the Mark effect and Tenacity. She mainly enhances the team's attack effectiveness by boosting attacks against marked enemies.

Analysis: Selena acts as a secondary DPS in the team, focusing on marking enemies and enhancing the team's attacks on marked targets.

SupportTier List

These characters are fully focused on supporting the team through healing, card drawing, AP generation, or buff/debuff effects, with damage taking a secondary role.

Seasonal Save Data

Chaos Manifestation

S Tier Recommended Character: Veronica

Veronica's primary value in Save Data comes from her ability to provide enormous draw power and, after Divine Epiphanies, a combination of draw plus AP generation for the team. She has transitioned fully into the Support category in Save Data as players optimize her decks away from dealing damage and toward pure team enablement.

Analysis: Veronica is considered an essential support in any team that requires fast deck circulation. Her powerful and mostly cost-free draw effects make her a core part of high-level team compositions, and she is virtually irreplaceable in the Save Data meta for teams built around her.

S Tier Recommended Character: Cassius

Cassius can shuffle the deck, replace cards, and use his ultimate Joker to search specific cards from the deck or discard pile. Following his rework, his new builds leverage Dice Trick's AP cost reduction to access powerful neutral epiphanies at low cost.

Analysis: While Cassius's card-loop playstyle was removed in his rework, he remains a top-tier support. New Cassius builds focus on reducing Dice Trick's 2-AP cost to 0 to gain access to the strongest neutral epiphanies, giving him continued relevance as one of the best precision-play supports in endgame content.

S Tier Recommended Character: Mika

Mika is currently the only character whose base deck can generate AP, making her one of the most valuable resources for teams that need to play more cards per turn. She provides strong healing and can sustain team survival in endgame content without compromising her core deck function.

Analysis: In Chaos mode, Mika has returned to S as one of the strongest comfort picks. The removal of Narja's exclusive access to Unique cards has closed the gap between them, and Mika's AP generation and healing make her genuinely difficult to replace in roguelike runs. She falls to A in Save following the loss of her primary synergy with the reworked Tressa.

A Tier Recommended Character: Nia

Nia has received a series of buffs to her healing and has gained new powerful teammates in Diana and Heidemarie. Her role as a discard engine — particularly as Diana's signature support — has significantly elevated her standing.

Analysis: Nia is Diana's signature support, and in content that favors discard mechanics, she can perform even beyond her current rating. She has risen to A in Chaos and A in Save, reflecting her much-improved viability compared to earlier seasons.

A Tier Recommended Character: Rei

Rei can enhance low-cost attack cards and strengthen Void cards. She can help with deck circulation, ensuring that DPS characters can draw key cards in a timely manner.

Analysis: In endgame mode, players tend to optimize damage, and Rei's buff effects are particularly effective for characters with high attack frequency but low initial card multipliers (such as Mei Lin and Kayron). She is considered one of the most versatile supports besides Mika.

Shielder Tier List

These characters focus on providing strong, sustained shields for the team while contributing to the team through support effects or sufficient damage output.

S Tier Recommended Character: Khalipe

Khalipe is a very powerful and easy-to-use character. She provides free damage, free shields, and stable AoE output. Her skills synergize with the Celestial tag: when any 2-cost or higher-cost card is played, Celestial cards are automatically triggered.

 Analysis: Khalipe can deal sufficient AoE damage to act as the team's damage dealer while providing adequate shields. Due to her ease of use and high effectiveness, she is recommended for players to pull.

A Tier Recommended Character: Magna

Magna provides strong survivability and crowd control capabilities. She has counterattack abilities, including AoE counterattacks that can apply Vulnerability. Her Ice Wall Epiphany can provide fixed, turn-cycle shields, effectively reducing team pressure.

Analysis: Magna's endgame capabilities are stronger than Maribell's. She can provide the team with survival guarantees, control effects, and damage boost effects, especially performing excellently in battles that require AoE and counterattack mechanics.

How to Build the Strongest Team？

In Chaos Zero Nightmare, the key to building the strongest team lies in synergy, card management, and Epiphany optimization. S Tier DPS characters usually need to be paired with support characters that can provide AP, Morale, or card manipulation.

Below are some examples of powerful synergistic teams :

1. Blade Rain Burst Team: Heidemarie + Hugo + Selena

Features: The current premier team composition in the half-anniversary meta. Heidemarie's Sword Rain III activates Effulgent Blades as extra attacks, each one independently triggering both Hugo's follow-up attacks and Selena's Coordinated Attacks. This creates a cascade of bonus damage that pushes total team output to the highest level in the game.

2. Discard Synergy Team: Diana + Nia + Cassius

Features: Diana's discard-based damage pairs naturally with Nia as a discard engine and Cassius for precise card search. Nia enables Diana's [Quietus] triggers while also providing healing support, and Cassius ensures both characters can find their key combo pieces efficiently.

3. Infinite Combo Team: Mei Lin + Rei + Mika (Chaos-focused)

Features: This team has smooth flow and extremely high sustained damage, making it one of the most stable combinations in Chaos Mode. Rei buffs Mei Lin's high-frequency attacks and Mika provides the AP generation to sustain the combo chain.

4. Upgrade Burst Team: Hugo + Tressa + Narja

Features: Both Hugo and Tressa rely on upgrade strategies, allowing the tactic to start quickly with minimal reliance on specific hand states. A smooth and reliable combination for players who prefer consistent execution.
