Zenless Zone Zero’s RPG elements make it crucial for players to understand each Stat in order for them to plan their combat strategy accordingly. Among the various novel Stats in the game, one, known asImpact, tends to particularly confuse newbies.
ManyZenless Zone Zeroplayers want to know precisely what this ability does and how it affects an Agent’s performance. As such, this guide explores every aspect of the Impact effect, explaining how to improve it and identifying which Agents have the highest potential to become your primary Impact inflicters.

What Does Impact Do In Zenless Zone Zero?
InZenless Zone Zero, Impact is a base stat that enhances theDaze accumulation ratio. Agents with higher Impact effects can stun enemies faster because their basic and special attacks replenish the Daze gauge more quickly.
By default, each Agent’s strikes and projectiles accumulate Daze points, which stun the enemy when they reach a specific amount. A Dazed (or stunned) enemy is immobilized for a few seconds, becoming more vulnerable to chained attacks. The Impact Effect accelerates this entire process.

Each Impact stat point contributes a small percentage to Daze buildup, which allows for more frequent stuns in combat.

How To Enhance Impact In Zenless Zone Zero
There are two ways to improve an Agent’s Impact inZenless Zone Zero: Getting specificCore Skill Enhancementsor unlocking specificW-Engines.
Unlock Core Skill Enhancements
Characters with higher Impact potential often achieve higher base Impact stats when you unlock their E Core Skill Enhancement. This skill can improve the overall ratio for the Impact effect of the Agent in question. However, you should note that Core Skill Enhancements are prerequisite-dependent. So, in order to achieve Core Skill Enhancement E, you must unlock A, B, C, and D in advance, and doing so will take some time.
You can unlock the first Core Skill Enhancement (A) once you reach level 15 with the Agent.

Unlock And Enhance W-Engines
W-Engines arecombat-enhancing pieces of equipmentthat buff the base and advanced stats of Agents. Certain models, like the Demora Battery Mark 2, also increase the equipper’s Impact Effect. This improvement is in percentage, not stat points. Enhancing a W-Engine can boost its stats, leading to an increase in Impact Ratio.
