Chaos Zero Nightmare: Kayron Mechanics Guide

In Chaos Zero Nightmare, the 5-Star Void attribute Psionic Kayron establishes a unique combat philosophy through his distinctive "card Exhaust" system. He doesn't rely on conventional offensive rhythms, but instead releases terrorizing damage beyond ordinary means through precise resource exchange and Void accumulation. Now, LDShop summarizes his skills and Mechanics for your reference.

 

Core Mechanics: Void & Card Exhaust

Kayron's entire combat system is built upon two core concepts: Void & Card Exhaust.

Futility: A special status card that is automatically Exhausted after use for 1 AP cost. Almost worthless when used alone, but serves as the power source for many of Kayron's unique skills.

Card Exhaust: Refers to the state where cards enter the graveyard after being used or removed by effects. The power of Kayron's core skills is closely tied to the cumulative number of cards Exhausted during combat, especially the number of Void cards Exhausted.

Simply put, Kayron's gameplay revolves around continuously generating and consuming Void cards, activating the additional effects of his core skills through accumulating "Exhaust count," thereby dealing devastating damage in the mid to late stages of combat.

 

Skills & Unique Cards Deep Dive

Core Engine Cards

• Echo of Futility (1-Cost Attack)

Role: The foundation of Kayron's operational system, crucial for rapidly accumulating Void count.

 

• Oath of Vanity (2-Cost Upgrade)

Effect: Changes all subsequently created 'Void' cards into Attack cards with 80% damage, 80% healing effect, and a cost of 1.

Strategic Significance: Completely transforms the awkward position of 'Void' cards, turning them from mere "fuel" into practical cards that can be used directly, greatly alleviating hand pressure.

Scaling Damage Cards

• Black Hole (2-Cost Attack)

Effect: Deal 240% damage. Increases damage by +40% per Exhausted card in this combat (Max 10 times).

Max Benefit: When the Exhaust requirement is met, can deal up to 640% single-target damage, serving as Kayron's core offensive skill.

 

• Echo of the Unbound (2-Cost Attack)

Effect: Deal 240% damage. Create 3 'Void' cards. Increase damage by +40% for each Void created.

Manifest Ego Boost: At E1, additionally creates 2 Void, increasing the damage cap to 440%.

• Effect: 4-Cost. Deal 200% damage to all enemies. Exhaust all Void Cards in hand and increase damage by 80% for each card Exhausted.
• Usage Timing: Typically used when holding a large number of Void cards in hand, serving both as area clearance and resource management.

 

Epiphany: Altering Damage Patterns

The Epiphany system provides diverse evolution paths for Kayron's skills:

• Echo of Futility: Can evolve into a zero-cost Attack that creates 2 Void cards and gains 30% damage per Void created this combat, possessing unlimited scaling potential.
• Black Hole: Can evolve to deal 60% damage to a random enemy and trigger additional attacks based on Exhausted card count (max 5 times), enabling multi-hit strikes; or evolve into an ultimate single-target burst with a 960% damage cap.
• Brand of Annihilation: Can evolve to have a significantly increased base cost but permanently reduce cost based on total Exhausted cards, enabling zero-cost area clearance in the late game.
• Oath of Vanity: Can gain the [Outbreak of War] keyword and turn Void into zero-cost, 100% damage Attack cards at the start of battle, providing excellent setup assurance.

 

Potential & Manifest Ego Key Nodes

Potential Refinement

• 3-1: 'Elimination' and 'Sphere' gain +50% damage and healing, and gain the effect to create 1 Void card, significantly improving basic cycle efficiency.
• 5-1: Increases damage for Kayron's 'Elimination'. Gains an additional bonus if Kayron's Attack is greater than 500.
• 7: When Kayron's Attack is greater than 600, Critical Damage is significantly increased, a key enabler for late-game damage.

Manifest Ego (Dupes)

E1: 'Echo of the Unbound' additionally creates 2 Void cards, accelerating resource accumulation.

E2: For every 2 Void cards used, deal 100% damage to all enemies, which can benefit from damage amplification, significantly improving Void utilization efficiency.

E3: 'Rift of Nothingness' can also Exhaust Void cards in the Graveyard, greatly enhancing ultimate flexibility.

E4: Whenever a Void card is used, gain 1 stack of 'Paradox of Nothingness' (For 1 turn, Kayron's attack card damage +10%, Max 3 stacks), providing substantial sustained damage amplification.

E6: Whenever a Void card is generated, 50% chance to apply one random debuff (Vulnerable/Weaken/Injured) to a random enemy, adding some crowd control utility.

 

Summary & Evaluation

Kayron is a typical late-game scaling main DPS. His strengths lie in:

• Astounding Damage Ceiling: Core skills 'Black Hole' and the Epiphany version of 'Echo of Futility' possess top-tier damage multipliers in the game, only growing stronger as combat progresses.
• Unique Resource Cycle: Through cards like 'Oath of Vanity', he transforms otherwise ineffective 'Void' resources into tangible damage and healing, creating a coherent and efficient mechanic.
• Considerable Team Contribution: While focused on damage, he can also provide healing through Epiphany variants and apply various debuffs via his E6.

Mastering Kayron demands strategic foresight and patience, as his early combat presence remains modest before reaching critical mass. Yet for those willing to navigate this buildup phase, the ultimate payoff is immense - witnessing his transformation into an overwhelming force that dominates the battlefield. Players who find satisfaction in tactical progression and character evolution will discover Kayron represents an exceptionally rewarding long-term commitment.
