Beryl Best Build Guide: Cards, Teams, Setup

In Chaos Zero Nightmare, Beryl is a 4-star character who specializes in late-game burst damage. Her unique Retain mechanic allows her to deal devastating damage once fully prepared. This guide will provide a comprehensive understanding of her skills, gear combinations, and team compositions.

Beryl Overview

Beryl is a 4-star Justice-attribute Ranger in Chaos Zero Nightmare, affiliated with the "Iron Rain" faction. Her core mechanic revolves around Retain, which allows her to accumulate card effects and unleash exceptionally high burst damage in later rounds. As a main damage dealer, she requires early-game setup to maximize her late-game explosive potential.

Beryl embodies the classic high-risk, high-reward carry, boasting unparalleled single-target devastation in the late game through her unique Retain mechanic, which allows for strategic card stockpiling and explosive turns supported by her exceptional card cycling. However, her prowess comes with significant caveats: she is a slow-starter requiring careful setup, critically vulnerable to any form of hand disruption, completely lacking in AOE capability, and demands a highly specific team built around protecting her and enabling her fragile engine.

Beryl is widely regarded as a T1 single-target specialist main carry in the game's launch version. Her rating is entirely dependent on a well-constructed team composition. She is not a plug-and-play universal unit—her ceiling is exceptionally high, but her floor is exceptionally low. She excels in single-target Boss battles but demands high operational skill and strict team synergy. Once her mechanics are mastered and she is paired with a suitable team, she becomes one of the strongest tools for overcoming high-difficulty single-target challenges.

 

Skill Analysis

Starter Cards

Launcher (1 Cost): A basic attack card dealing 112% damage. Its low cost makes it ideal for filling gaps in your action economy.

Charged Launcher (2 Cost): A high-cost attack card dealing 246% damage. Serves as a conventional damage option when key Spark Cards are unavailable.

Barrier (1 Cost): A defensive skill providing a 112% Shield, crucial for sustaining survivability in high-pressure situations.

Opening Found (1 Cost): [Retain] Deals 134% damage. When retained, grants 1 additional attack within the next turn, making it essential for setting up burst phases.

Spark Cards

Charged Shot (2 Cost): [Retain] Deals 228% base damage. If used while in the Retain state, its damage is additionally increased by 80%. This is Beryl's most critical single-target burst skill.

Guilty Pleasure (0 Cost): [Consume] Draw 3 cards immediately upon use, then this card is consumed. Its powerful card-drawing capability helps quickly cycle through the deck to search for key skills.

Unlimited Firepower (1 Cost): A powerful Spark skill (exact effects require in-game verification, typically provides multi-hit attacks or cost reduction for burst damage enhancement).

Heavy Weapons Specialist (0 Cost): Can create 1 "Opening Found" or "Charged Shot" and reduce its Cost by 1. This skill both supplies key cards and optimizes Cost, serving as the core of the skill rotation.

 

Stats and Equipment Setup

Core Stat Priority

Crit Rate: The top priority stat. Aim for over 65% outside of battles. With Potential bonuses, this can reliably reach over 80%, ensuring the burst damage from Charged Shot consistently crits.

Crit Damage: The core offensive stat to maximize after meeting the Critical Rate threshold. As a Main Carry, the higher her Critical Damage, the more terrifying her burst potential becomes.

Attack: Recommended to reach around 920 outside of battles. Combined with weapon stats and in-battle buffs, this allows her to easily break the 1000 Attack threshold, directly increasing the damage multiplier for all her skills.

Beryl Best Memory Fragments

Conqueror's Aspect and Black Wing Sets for Crit Damage and Attack Boost

Conqueror's Aspect Set

Black Wing Set

The Conqueror's Aspect set increases the critical damage of her 1-cost cards by 35%, which are her Launcher and Opening Found cards, sometimes the Charged Shot after summoning it using the Heavy Weapons Specialist card. The Black Wing set directly boosts her attack to increase her damage potential.

Beryl Best Equipment

Gear Focused on Damage

Weapon	Armor	Accessory
The Destruction of Erysichthon	Growing Carapace	Pulsating Egg

The Destruction of Erysichthon gives Beryl’s attack cards a chance to deal an additional hit, making it great for her high-damage cards to allow them to hit twice for more damage. Growing Carapace increases her resilience by providing a shield each turn. Pulsating Egg directly boosts Beryl’s Attack and HP stats by 10%.

 

Gameplay Guide

Basic Rotation Techniques

Begin the battle by using "Opening Found" to enter the [Retain] state, preparing for an extra attack next turn. Follow up with "Guilty Pleasure" to quickly draw key cards like "Charged Shot" and "Heavy Weapons Specialist". Use "Heavy Weapons Specialist" to generate discounted "Opening Found" or "Charged Shot", conserving resources for your burst phase.

Sustained Damage Rotation

Always maintain one [Retained] "Opening Found" or "Charged Shot" in your hand. Utilize "Heavy Weapons Specialist" to consistently replenish key cards and sustain your skill rotation. Activate "Charged Shot" while in the [Retain] state to unleash a devastating 404% single-target burst.

Burst Rotation

Preparation Phase

Use "Guilty Pleasure" to cycle through your deck and "Heavy Weapons Specialist" to stockpile at least one discounted "Charged Shot". Retain one "Opening Found" in hand to trigger extra attacks.

Spark Selection Strategy

• Charged Shot: Prioritize Sparks that reduce its Cost, increase Critical Damage, or add extra hits. This optimizes your core burst skill for lower cost and higher damage.
• Opening Found: Focus on Sparks that grant additional attacks, reduce Cost, or allow card draw upon use. Increasing the number of attacks significantly boosts total burst damage.
• Heavy Weapons Specialist: Choose Sparks that grant the [Retain] status upon card generation, create additional cards, or reduce generated card Costs. This dramatically improves rotation efficiency.
• Guilty Pleasure: Opt for Sparks that prevent consumption, provide extra card draw, or reduce other cards' Costs. This enables smoother deck cycling and faster assembly of key card combinations.

Conclusion

Beryl is a quintessential late-game nuke, balancing tremendous potential with significant execution demands. Not recommended for beginners during early-game progression: her slow-starting nature, reliance on the Retain mechanic, and vulnerability to hand disruption can easily lead to frustration in the initial stages. However, she is a treasure for experienced players: once she overcomes her early weakness and her gear and Potential are fully developed, her apocalyptic single-target burst becomes irreplaceable. In boss-rush speedruns and high-difficulty challenges, she stands as the ultimate trump card capable of decisively ending battles.
