Hey everyone, it's your guide-hungry Proxy here! 🎮 Let's dive deep into the world of Observation Data in Zenless Zone Zero. As of 2026, understanding these two types—Exploration and Combat—is still absolutely crucial for ranking up and grabbing those sweet, sweet Polychromes. I've spent countless hours in the Hollow, and I'm here to break it all down for you, so you don't have to learn the hard way like I did!

First things first, let's talk about Exploration Observation Data. This is the stuff you actively hunt for while navigating the Hollow as your trusty (and adorable) Bangboo. Think of it as a collect-a-thon during the puzzle and exploration phases.

Where to Find Exploration Data? 🕵️‍♂️

You can snag this data from three main sources:

  • Mewmew Challenges: Every single one you complete for Officer Mewmew rewards you with one piece of Exploration Data. Just don't forget to collect your medal! It's a perfect side activity when you need a break from the main Commissions.

  • Story & Exploration Commissions: This is the primary hunting ground. Three pieces are hidden in every Story and Exploration Commission.

What Does It Look Like? 👀

Keep your eyes peeled on the TV screens! The data appears as a black sphere made of triangles, sitting inside a black circle with a vibrant orange background. It's pretty distinct once you know what to look for.

Pro-Tips for the Hunt!

Finding all three in a commission is a game-changer. It boosts your commission rank and showers you with Polychromes. Plus, you often need a certain amount to increase your overall Proxy Rank.

  1. Track Your Progress: Easy peasy! On the commission selection screen, look next to the commission name. You'll see three circles that fill up as you collect data. You can also check your total haul in your profile under 'Your Info'.

  2. It's a Bangboo-Only Affair: Remember, you can only find this data while exploring as a Bangboo, not during combat. This means locations vary wildly! You might need to solve a puzzle, open a locked door, or clear a floor of monsters to reach it.

  3. Use Your Camera! A lifesaver tip: you can zoom out and move the camera independently of your Bangboo. Use this to scout ahead and plan your route to spot those orange screens from afar!

  4. No Stress on Replays! The best news? Once you find a piece of data, it's permanently collected. If you miss one or have to bail, just replay the commission. You'll only need to grab the ones you missed, making it a focused cleanup run.

Now, let's switch gears to Combat Observation Data. This one's for all you action junkies! Unlike exploration data, you don't find this—you earn it by being awesome in Combat Commissions.

How to Earn Combat Data? ⚔️

Simple: complete challenges! Each Combat Commission has three specific challenges (hence, three pieces of data). These can be things like:

  • Finishing the commission (the gimme!).

  • Beating it within a strict time limit.

  • Achieving a high combo or taking minimal damage.

You gotta complete all three challenges to get all the data for that commission. The reward? You guessed it: more Polychromes and a higher commission rank!

Keeping Score in Combat

Tracking is just as easy here. The same three-circle system next to the commission name shows your Combat Data progress. Your grand total is, again, in your profile's 'Your Info' section. You'll also get a nice summary screen at the end of each combat run showing what you earned.

Why Bother with Both?

Let me put it this way:

Data Type How to Get Key Rewards Vibe
Exploration Find hidden objects in the Hollow as a Bangboo. Polychromes, Commission Rank, Proxy Rank Up Chill, scavenger hunt. 🧩
Combat Complete specific combat challenges. Polychromes, Commission Rank Intense, skill-based. 🔥

Grinding both is the secret sauce for efficient progression. Polychromes are the premium currency for pulls, and ranking up unlocks new content and challenges. It's a core loop that feels super rewarding.
