Core Combat Stats
What Does PEN Do in ZZZ?
PEN (Defense Penetration) reduces the effectiveness of an enemy’s Defense when calculating damage. When an Agent deals damage, PEN allows a portion of that damage to ignore enemy Defense, resulting in higher final damage. PEN is most impactful against enemies with high Defense values, where raw ATK alone becomes less efficient.
PEN applies during the damage calculation stage and directly affects how much mitigation an enemy can apply. This makes PEN especially valuable in late-game content and against elite or boss enemies. Without PEN, damage dealt to high-Defense targets is significantly reduced.
What is PEN Ratio in ZZZ?
PEN Ratio is a percentage-based stat that determines how much of an enemy’s Defense is ignored during damage calculation. Unlike flat PEN, which subtracts a fixed value, PEN Ratio scales based on the target’s Defense stat. This allows PEN Ratio to scale more effectively against enemies with higher Defense.
PEN Ratio is applied multiplicatively during damage calculations and becomes increasingly valuable as enemy Defense increases. Because of this, PEN Ratio is generally stronger than flat PEN in endgame encounters. Agents or W-Engines that provide PEN Ratio are optimized for fighting durable enemies.
What Is Anomaly Proficiency in ZZZ?
Anomaly Proficiency increases the damage dealt when an Attribute Anomaly is triggered. It affects the strength of the Anomaly’s damage component but does not change how quickly buildup occurs. Higher Proficiency results in a stronger payoff once an Anomaly activates.
This stat is most valuable on Agents whose damage primarily comes from triggering Anomalies. Without sufficient Proficiency, Anomaly triggers occur but deal reduced damage. Proficiency scales independently from ATK and CRIT.
What Is Anomaly Mastery in ZZZ?
Anomaly Mastery increases the rate at which Attribute buildup is applied to enemies. Higher Mastery allows Agents to trigger Anomalies more frequently by filling the buildup threshold faster. It does not increase the damage of the Anomaly itself.
Mastery determines consistency rather than burst. Agents with low Mastery may struggle to trigger Anomalies within short combat windows. This stat is critical for maintaining pressure in prolonged fights.
Anomaly Mastery vs Anomaly Proficiency
Anomaly Mastery controls how fast Anomalies trigger. Anomaly Proficiency controls how strong those Anomalies are. Mastery affects Anomaly buildup speed. Proficiency affects damage after the attribute anomaly is triggered. Both stats are required for Anomaly agents.
What Is Impact in ZZZ?
Impact is a combat stat that determines how quickly an Agent can build Daze on enemies through attacks and skills. Higher Impact values cause attacks to fill the enemy’s Daze meter faster, shortening the time needed to force enemies into the Stunned state. Impact does not increase damage directly, but it strongly affects team damage windows and combat pacing.
Impact is primarily relevant for Stun-specialty Agents, whose role is to control enemies rather than deal damage. When Impact is low, enemies take longer to Stun, reducing overall team efficiency. As enemy durability increases in later content, Impact becomes increasingly important for consistent Stun uptime.
What Is Daze in ZZZ?
Daze are points applied to enemies when they are hit by attacks. As the Daze accumulates, enemies move closer to entering the Stunned state. The Daze meter resets once an enemy becomes Stunned.
Daze buildup is influenced by Impact, enemy type, and attack properties. Normal enemies generally build Daze faster than elites or bosses, which have larger Daze thresholds. Accumulating Daze faster is critical for triggering Stuns at the right time and enabling burst damage opportunities.
What Is Energy in ZZZ?
Energy is a resource used to activate EX Special Skills during combat. It is generated through attacking enemies, performing actions, and interacting with combat systems such as Assists. Each Agent has their own energy meter.
What Are Decibels in ZZZ?
Decibels are the points used to activate Ultimates in Zenless Zone Zero. Decibels are generated through combat actions such as basic attacks, EX skills, dodge counters, etc. Decibels are consumed entirely when an Ultimate is used. Once an Ultimate is activated, the Decibel points reset to zero.
Stun & Chain Mechanics
How Does Stun Work in ZZZ?
Stun occurs when an enemy’s Daze gauge is fully filled. Stunned enemies enter a temporarily incapacitated state. Stunned enemies also receive increased damage from all sources. This state creates a high-value damage window that teams are designed to exploit.
The duration of Stun depends on the enemy type. Normal enemies remain stunned longer than elites or bosses. After the stun ends, the enemy’s Daze gauge resets. When an enemy becomes Stunned, it becomes vulnerable to Chain Attacks.
What Are Chain Attacks in ZZZ?
Chain Attacks are powerful follow-up attacks that trigger when an opponent is stunned. They allow Agents to perform coordinated attacks in sequence, dealing high damage and extending pressure during Stun. Chain Attacks are one of the main rewards for successful Daze management.
Each Agent can typically participate once per Chain sequence, depending on team composition and conditions. Chain Attacks consume the Stun window, so timing and order matter. Using Chain Attacks incorrectly can shorten the damage opportunity.
How to Trigger Chain Attacks in ZZZ?
Chain Attacks are triggered when players hit the stunned enemies with a final basic attack or skill. Players can then switch between eligible Agents to execute their Chain Attacks in sequence. The chain ends once the allowed number of Agents have acted or the Stun window expires.
Anomalies & Disorder
What Are Attribute Anomalies in ZZZ?
Attribute Anomalies are status effects applied to enemies after sufficient Attribute buildup is accumulated through attacks. When an Attribute Anomaly is triggered, it deals damage or applies debuffs based on the element used. Anomalies are a core damage source for Anomaly-specialty Agents. Enemies can only hold a limited set of active Anomalies at a time. Managing buildup timing determines when and how often Anomalies trigger.
What Is Disorder in ZZZ?
Disorder is a special reaction triggered when a new Attribute Anomaly is applied while another Anomaly is already active on the enemy. When Disorder occurs, it deals additional damage. Disorder damage scales based on the triggering Anomaly’s stats. It does not require enemies to be Stunned. This mechanic encourages multi-element team compositions.
How to Trigger Disorder in ZZZ?
To trigger Disorder, apply an Attribute Anomaly to an enemy using one Agent. Then switch to an Agent with a different Attribute and apply enough buildup to trigger a second Anomaly. Disorder will activate automatically once the second attribute anomaly is triggered.
Aftershock
What Is Aftershock in ZZZ?
Aftershock is an effect that triggers after certain attacks or conditions are met, depending on an Agent’s kit, W-Engine effects, or passives. It is not a universal mechanic and only occurs when explicitly enabled by skills or equipment. Aftershock damage is calculated separately from the original hit and does not replace the primary attack.
Aftershock is typically used to add extra damage. These additional hits can contribute to Anomaly buildup or trigger other effects depending on the Agent.
How to Trigger Aftershock in ZZZ?
Aftershock is triggered by using the specific conditions listed in an Agent’s abilities, passives, or equipped W-Engine effects. These conditions may include landing certain attacks, using skills after swaps, or hitting enemies in specific states. Once the condition is met, the Aftershock damage is applied automatically without additional input.
Because Aftershock activation is conditional, it cannot be forced through basic attacks alone. Players must follow the correct rotation or timing to consistently trigger it. Reading ability descriptions carefully is required to understand how and when Aftershock occurs.
Dodging & Survival
How Does Dodging Work in ZZZ?
Dodging allows Agents to quickly reposition and avoid incoming attacks. A successful dodge prevents damage and can interrupt an enemy attack if mixed with counterattack. Dodging is a core mechanic and is required to handle harder stages in ZZZ. Dodging has a brief window and limited I-frames. Repeated dodging without awareness can leave Agents vulnerable once the window ends. Efficient dodging reduces damage taken and preserves team rotation.
What Is a Perfect Dodge in ZZZ?
A Perfect Dodge occurs when a dodge is executed at the moment a gold or red flash from the enemy appears. When performed correctly, it triggers a slow-motion effect that creates a short opening for counterattacks. Perfect Dodges reward precise timing rather than repeated evasive movement.
Perfect Dodges do not consume additional resources beyond the dodge itself. They are especially useful against aggressive enemies with predictable attack patterns. Mastering Perfect Dodge timing significantly improves survivability.
What Is a Dodge Counter in ZZZ?
A Dodge Counter is a follow-up attack that can be performed immediately after a successful Perfect Dodge. This counterattack deals damage while capitalizing on the enemy’s recovery window. Dodge Counters allow defensive actions to convert directly into offensive actions.
Dodge Counters are only available after a Perfect Dodge, not a normal dodge. Using them consistently increases overall damage without committing to risky attacks. This mechanic encourages precise defensive play rather than passive evasion.
Assist System
How Do Assists Work in ZZZ?
Assists allow Agents to intervene during enemy attacks or ally actions to reduce damage and maintain combat flow. When an Assist is triggered, another Agent temporarily enters the field to block, evade, or counter an incoming attack. This system replaces traditional blocking mechanics and emphasizes timing and positioning. Assists are activated in response to specific enemy attack cues. Using Assists correctly prevents damage and preserves momentum. Poor Assist timing can leave the team exposed.
What Is a Parry Assist in ZZZ?
A Parry Assist is triggered when an enemy attack is blocked at the correct timing window. Successful parry assist negates incoming damage and can stagger or interrupt the enemy. Parry Assists are best used against direct, heavy-hitting attacks.
Parry Assists require precise timing and positioning. Missing the timing results in taking full damage. Mastery of Parry Assists greatly improves survivability in difficult encounters.
What Is an Evasive Assist in ZZZ?
An Evasive Assist is triggered when an Agent avoids an incoming attack by quickly switching characters. Instead of blocking, the assisting Agent evades and repositions, avoiding damage entirely. This type of Assist is safer against wide or unblockable attacks.
Evasive Assists do not interrupt enemies as strongly as Parry Assists. They are best used when blocking would be unsafe or unreliable. Choosing the correct Assist type depends on the enemy attack pattern.
What Is a Quick Assist in ZZZ?
A Quick Assist is a follow-up action that occurs after certain Assists or combat events. It allows an Agent to immediately attack or apply effects after entering the field. Quick Assists help maintain offensive pressure while rotating characters.
Quick Assists trigger automatically when the current agent is launched. An "assist" prompt will appear on the right screen when quick assist is available. Efficient use of Quick Assists improves rotation speed and damage uptime.
