Tier Classification
We adopt a four-tier classification to intuitively present the comprehensive performance of characters in the game's highest difficulty scenarios:
S Tier: Exceptional and consistent strength, making them the top choices in the current version. They can stably clear high-difficulty challenges without relying on luck factors such as specific Epiphanies or equipment. Compatible with any team composition, offering maximum flexibility and efficient adaptation to various tactics.
A Tier: Excellent and highly competitive, sufficient to handle high-level challenges. Highly effective in most team compositions and easy to setup, only slightly inferior in strength to S Tier characters. They require specific Epiphanies or equipment to unleash their full potential.
B Tier: Possess practical value but have obvious limitations. A reliable choice in the early progression stage, yet struggle to overcome the hardest challenges without the assistance of high-strength characters. Can fill in specific roles in team compositions to be effective, but require more effort in optimizing configurations to function properly.
C Tier: Weak performance in high-difficulty scenarios, or highly dependent on specific mechanisms to be effective. Their overall capabilities are comprehensively surpassed by characters of other tiers, resulting in low priority in practical combat.
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.
Tier | Characters |
S | Mei Lin, Chizuru, Haru, Hugo |
A | Renoa |
B | Yuki, Kayron, Luke |
C | Amir |
S 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.
S 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.
A 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.
Tier | Characters |
S | Veronica, Cassius |
A | Tressa, Selena, Orlea |
B | Owen, Beryl |
C | Rin, Lucas |
S Tier Recommended Character: Veronica
Veronica has the best card draw ability in the game currently, and many of her card draws cost 0. Beyond card draws, her deck essentially consists of upgrades, making her the ultimate deck thinner, able to easily draw all key combo components every turn. She can also provide background damage through card reloads.
Analysis: All of Veronica's abilities are achieved while dealing stable damage for free. Her powerful card draw ability makes her a core part of any team that requires fast deck circulation and card drawing, with extremely high versatility.
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.
Support Tier 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.
Tier | Characters |
S | Mika, Cassius |
A | Rei |
B | Nia |
C | Orlea, Lucas |
S Tier Recommended Character: Mika
Mika is currently the only character whose base deck can generate AP, an ability in high demand in the game. She provides one of the best healing stats among all characters and has the ability to maintain team survival in endgame content without affecting her core deck.
Analysis: Mika greatly expands the action resources available to the team each turn. The community generally considers her irreplaceable because her presence significantly increases the team's ability to execute actions.
S Tier Recommended Character: Cassius
Cassius can shuffle the deck, replace cards, or use his ultimate move Joker to grab specific cards from the deck or discard pile.
Analysis: Cassius performs excellently in endgame content, helping the team find the required combo components as quickly as possible. His direct search ability makes him very flexible in teams that require high-precision card management and timing coordination.
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.
Tier | Characters |
S | Khalipe |
A | Magna |
B | Maribell |
C | Amir, Owen |
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. Infinite Combo Team: Mei Lin + Rei + Mika
Features: This team has a smooth flow and extremely high sustained damage, making it one of the most stable and reliable combinations in Chaos Mode.
2. Upgrade Burst Team: Hugo + Tressa + Nia
Features: This is a smooth and highly reliable combination. Both Hugo and Tressa rely on upgrade strategies, making the tactic start quickly and less affected by resources and hand card status.
3. High Burst Team: Khalipe + Mika + Magna
While maintaining high survivability, both Khalipe and Magna can deal AoE damage, making this team very efficient.
