Stats determine an Agent's performance in combat in Zenless Zone Zero (ZZZ). Learn more about what each Stat does, the difference between PEN Ratio and PEN Stats, and how to increase them in this guide!

ZZZ Stats Explained

Character Stats Explanation

Stats determine how well an Agent performs in combat. Each stat has a different effect, and their base amount can be increased through level up or by equipping gear like W-Engines and Drive Discs.

You can see more details about the Agent's stats by clicking on the "Basic Stats" button (with the Agent's Attribute and Attack Type) right next to their level.

Other Stats

PEN Ratio Stat vs PEN Stat

Both PEN Ratio and PEN stats ignore the target's DEF stat, thus increasing your damage output even higher. The difference is that one can be better than the other depending on the target's DEF.

PEN Ratio will ignore a percentage of the target's DEF. This means the tankier your enemy is, the more their DEF will be penetrated, making them squishier.

On the other hand, PEN will ignore a flat amount of the target's DEF. This stat works better than PEN Ratio against enemies with low DEF, as the reduction will be higher.

Example DEF Reduction with PEN Ratio and PEN

The table above shows how much DEF will 40% PEN Ratio and 40 PEN penetrate from targets with 200 DEF and 60 DEF.

Both stats can stack with each other but the calculation is not yet confirmed, as in if the flat PEN shreds the target's DEF first before PEN Ratio takes effect or the other way around.

How to Increase Stats

HP, ATK, and DEF Increase on Level Up

Leveling up your Agents using Investigator Logs also increase their HP, ATK, and DEF stats.

How to Level Up Characters

Equip W-Engines

Equipping W-Engines onto Agents also increases their stats, depending onto their Base Stat and Advanced Stats. Players can also level them up as they would an Agent, and it may gain higher and more stats upon leveling up.

Each W-Engine has a passive effect that, depending on the effect, may further boost a character's stats.

Other Stats Increase Through Drive Discs

Although they also provide boosts for HP, ATK, and DEF stats, Drive Discs also increase the other stats of your Agent. These gear also give bonuses should you equip 2 pieces or 4 pieces of the same set.

The substats that each Drive Disc provides are randomized, so you might need to grind to find the perfect set of Drive Discs for each Agent.
