Zenless Zone Zero Disc Drive Farming Guide: Best Sets and Stats

Drive Discs are the gear layer in Zenless Zone Zero, and they quietly carry a huge chunk of your late-game power. Six discs per agent, a main stat and up to four substats on each, plus set bonuses when you match pieces. If you've played Genshin or Star Rail, the shape of this will feel familiar. The good news is that ZZZ gives you way more aim than those games do. You can target a set, then a slot, and eventually even the main stat you want. That turns the farm from a slot machine into something you can actually plan.

Here's the whole picture: where the discs come from, which main stats matter for each role, which set combos are worth your Battery, and how to tell a keeper from vendor trash before you waste Plating Agents on it.

Where to Farm Disc Drives by Suite

Area Patrol, formerly Routine Cleanup

Your main source is Area Patrol, which a lot of players still call Routine Cleanup because that was its name for the first year or so. Same thing. You reach it through the VR Device at Scott Outpost once you're Inter-Knot level 26 and you've finished the second part of the Belobog Story Commission plus Trace to the Source. Roland messages you the next day, you talk to him, and the mode opens up.

Every run costs 60 Battery Charge. Battery caps at 240 and refills at 1 point every 6 minutes, so a natural day gives you about 240 points, which is four runs. Spend it on the right stage.

Each stage drops discs from exactly two sets. That's the key thing to understand before you dump a week of Battery: you're not farming "discs," you're farming a specific pair of sets, and you pick the stage that holds the pair you want.

The stage list

| Stage | Sets dropped | Who wants it | |---|---|---| | 1 | Swing Jazz, Chaotic Metal | Supports, Ether attackers | | 2 | Hormone Punk, Fanged Metal | Physical attackers | | 3 | Shockstar Disco, Thunder Metal | Stunners, Electric attackers | | 4 | Woodpecker Electro, Soul Rock | Crit attackers, defenders | | 5 | Puffer Electro, Inferno Metal | Fire attackers, ult-reliant carries | | 6 | Freedom Blues, Polar Metal | Anomaly agents, Ice attackers | | 7 | Chaos Jazz, Proto Punk | Fire/Electric anomaly, shielders | | 8 | Branch & Blade Song, Astral Voice | Crit anomaly, quick-assist teams | | 9 | Phaethon's Melody, Shadow Harmony | Aftershock and dash builds | | 10 | Yunkui Tales, King of the Summit | Stunners, burst carries | | 11 | Dawn's Bloom, Moonlight Lullaby | Basic-attack carries, supports | | 12 | White Water Ballad, Shining Aria | Physical crit, Ether anomaly | | 13 | Bunny in Wonderland, Notes from the Chained | Defense scalers, Ice anomaly | | 14 | Wuthering Salon, The Sky Ablaze | Windswept squads | | 15 | Feathered Fate, Thorned Rose | Newer anomaly builds |

HoYo adds a fresh suite most patches, so the tail of that list keeps growing. The top half has been stable for a long time, and stages 3, 4, 6, and 8 cover most teams you'll ever build.

Bardic Needle tuning

The Music Store on Sixth Street, run by Elfy, is the targeted route. Instead of hoping the stage drops the piece you need, you feed it Master Copies and it crafts discs directly. You get Master Copies from dismantling the discs you don't want, so the loop is: farm a stage, keep the winners, break down the rest, tune for the slot you're missing.

The store levels up with your Inter-Knot level, and each level adds control:

• Level 1 (base): Beginner Tuning with Audio Booster Master Copies. B and A-rank discs only. You can set a Track, meaning you pick the set.
• Level 2 (IK 35): Intermediate Tuning with Noise Reduction Master Copies. S-rank becomes possible, and you can pick which of the six partitions the disc fills.
• Level 3 (IK 40): Advanced Tuning with Hi-Fi Master Copies. S-rank is guaranteed, and Main Stat Orientation unlocks, letting you choose the main stat.

That last one is a big deal. Set the track, pick the partition, pick the main stat, and you've removed almost all the randomness from getting a usable piece. Tuning Calibrators are what you spend to lock that main stat. They come from the battle pass and from the Hollow Zero shop for 2,000 Investigation Merits, and the supply is pretty thin, so save them for a slot 4 or 5 that you've been chasing forever.

When to actually start

Not at level 26. S-rank discs don't drop reliably until the enemies you're fighting hit level 40, so serious farming below Inter-Knot 40 mostly produces gear you'll replace. Push story, level your agents and W-Engines first.

Inter-Knot 40 is when you go all in, because Advanced Tuning and reliable S-rank drops arrive together. Inter-Knot 50 unlocks the top-tier Area Patrol stages, which give the best substat quality in the game. Start caring at 40, start grinding at 50.

Priority Main Stats for DPS, Stun, and Support Roles

Slot rules first

Slots 1, 2, and 3 are locked. Slot 1 is always flat HP, slot 2 is always flat ATK, slot 3 is always flat DEF. There's no choice there, so those slots are all about substats.

Everything you actually decide happens in slots 4, 5, and 6:

| Slot | Possible main stats | |---|---| | 4 | CRIT Rate, CRIT DMG, ATK%, Anomaly Proficiency, HP%, DEF% | | 5 | ATK%, PEN Ratio, elemental DMG Bonus, HP%, DEF% | | 6 | ATK%, Impact, Energy Regen, Anomaly Mastery, HP%, DEF% |

At S-rank and level 15, the big ones max out like this: CRIT Rate hits 24%, CRIT DMG hits 48%, ATK% and HP% hit 30%, DEF% hits 48%, PEN Ratio hits 24%, and any elemental DMG Bonus hits 30%. Slot 6 role stats are flat values rather than percentages, so Impact, Energy Regen, and Anomaly Mastery are straight numbers there.

Attack DPS

Standard crit carry wants CRIT Rate or CRIT DMG in slot 4, their elemental DMG Bonus in slot 5, and ATK% in slot 6. That's the template for Zhu Yuan, Ellen, Harumasa, Soldier 11, Evelyn, and the rest of that crowd.

Slot 5 is where people stall. Elemental DMG Bonus is usually a bit ahead of ATK% when both are available, but not by a mile, so an ATK% piece with great substats beats a DMG Bonus piece with junk on it. Don't sit on a hole for three weeks waiting for perfect.

Anomaly DPS

Anomaly agents like Jane, Yanagi, Burnice, and Miyabi swap the whole priority. Slot 4 goes to Anomaly Proficiency, slot 5 to ATK% or PEN Ratio, slot 6 to Anomaly Mastery. Their damage comes from stacking status effects and triggering Disorders, not from crit fishing, so crit mains are close to dead weight on them. Atk and proficiency do the real work.

Stun

One stat rules this role: Impact in slot 6. That's non-negotiable for Lycaon, Qingyi, Lighter, Koleda, and anyone else whose job is filling the Daze bar. Slots 4 and 5 are flexible, since stunners mostly want enough ATK to make their stun-window hits count and enough survivability to not get deleted. Crit Rate in slot 4 is a common pickup for stunners who do real damage during the burst window.

Support

Energy Regen in slot 6, every time. Supports live on their EX Specials and ultimates coming back fast, and regen is the stat that makes that happen. Astra Yao, Soukaku, Lucy, and Nicole all want it. Beyond that, HP% or ATK% depending on whether the character scales off one or the other, and Lucy's boar piggybacking off her stats makes ATK% builds on her surprisingly effective.

Best 4-Piece and 2-Piece Set Combinations

Six slots means you either run three 2-piece sets or one 4-piece plus one 2-piece. The 4+2 split is what most endgame builds land on, and it's what you should be aiming for once your inventory has some depth. Early on, 2-2-2 with correct main stats beats a broken 4-piece with wrong ones, so use that as a bridge.

Crit attacker sets

Woodpecker Electro is the workhorse. Two-piece gives 8% CRIT Rate, and the four-piece pumps ATK by 9% for 6 seconds whenever you land a crit with a Basic Attack, Dodge Counter, or EX Special, with each skill's buff tracked separately. Because it triggers on stuff you're doing anyway, it's basically always on. Farm it on stage 4.

Astral Voice is the other big generalist. Two-piece is 10% ATK, and the four-piece hands out stacking buffs whenever someone enters via Quick Assist, up to 3 stacks of 8% extra damage for the character swapping in. Quick-assist teams love it. Stage 8.

Elemental sets outperform these when the condition lines up. Thunder Metal (2pc Electric DMG +10%, 4pc +28% ATK while an enemy is Shocked) and Inferno Metal (2pc Fire DMG +10%, 4pc +28% CRIT Rate for 8s after hitting a Burning enemy) are straight-up stronger than the generalist sets, as long as someone in your squad is applying the status. Chaotic Metal gives Ether attackers 20% CRIT DMG from the four-piece alone and pairs beautifully with Zhu Yuan.

Anomaly sets

Freedom Blues is the default: 2pc gives 30 Anomaly Proficiency, and the 4pc shreds the target's Anomaly Buildup RES when your EX Special connects, which makes everything stack faster. Chaos Jazz is the alternative for Fire and Electric anomaly, handing out 15% to both elements on the four-piece plus an off-field damage boost that suits Burnice perfectly. Branch & Blade Song covers the crit-anomaly hybrids like Miyabi, with a 16% CRIT DMG two-piece and a four-piece that adds more crit damage once you're sitting on 115+ Anomaly Mastery.

Stun sets

Shockstar Disco has been the stunner set since launch. 2pc is 6% Impact, and the 4pc makes Basic, Dash, and Dodge Counter attacks inflict 20% more Daze on the main target. Since those are exactly the moves a stunner spams, it's a clean fit. King of the Summit is the newer rival, giving 6% Daze on the two-piece and a four-piece tied to a stunner's EX Special and Chain Attacks. Both are good. A lot of high-end builds run King of the Summit 4-piece with a Shockstar Disco 2-piece, or the reverse.

Support sets

Swing Jazz owns this category. 2pc is 20% Energy Regen, and the 4pc grants the whole squad 15% more damage for 12 seconds whenever the wearer launches a Chain Attack or ultimate. That's a team-wide buff on a support who's chain attacking constantly anyway. Moonlight Lullaby covers support-specific scaling if you need it, and Proto Punk is the shielder pick with 15% stronger shields on the two-piece.

What this looks like on real agents

| Agent | 4-piece | 2-piece | |---|---|---| | Zhu Yuan | Chaotic Metal | Woodpecker Electro | | Ellen | Polar Metal | Woodpecker Electro | | Evelyn | Hormone Punk | Woodpecker Electro | | Soldier 11 | Woodpecker Electro | Inferno Metal | | Miyabi | Branch & Blade Song | Woodpecker Electro | | Jane | Fanged Metal | Freedom Blues | | Yanagi | Thunder Metal | Freedom Blues | | Burnice | Chaos Jazz | Inferno Metal | | Qingyi | Shockstar Disco | Swing Jazz | | Lycaon | King of the Summit | Shockstar Disco | | Astra Yao | Astral Voice | Swing Jazz | | Soukaku | Swing Jazz | Astral Voice |

Woodpecker Electro shows up as the 2-piece over and over, and that's not a coincidence. An 8% CRIT Rate two-piece is one of the strongest filler bonuses in the game, so stage 4 is almost never a wasted trip.

Substat Value and Reroll Efficiency

How substats actually grow

An S-rank disc starts at level 0 with either 3 or 4 substats. It levels to 15, and every 3 levels it rolls once, at 3, 6, 9, 12, and 15. If it has fewer than 4 substats, that roll adds a new line. If it's already at 4, the roll dumps an extra value into one existing line. So a disc that starts with 4 substats is better in a subtle way, since every single roll goes into upgrading something instead of unlocking a slot for a stat you might not want.

One line can end up with 6 total rolls if it starts with one and gets picked all five times. Rare, but it's where the monster pieces come from.

What a roll is worth

Per roll on an S-rank disc:

| Substat | Per roll | Maxed (6 rolls) | |---|---|---| | CRIT Rate | 2.4% | 14.4% | | CRIT DMG | 4.8% | 28.8% | | ATK% | 3% | 18% | | Anomaly Proficiency | 9 | 54 |

Keep those CRIT numbers in your head, because they set expectations. A "great" CRIT Rate substat that landed 4 rolls is sitting around 9.6%. That's real, but it's not going to carry a build by itself. Substats are gravy. Main stats and set bonuses are the meal.

For crit carries, aim for roughly a 1:2 ratio of CRIT Rate to CRIT DMG, so something like 70% rate and 140% damage. If you're at 95% rate and 110% damage, you've overshot and every point of rate past the cap is doing nothing.

There's no true reroll

Worth being straight about this, because the word gets thrown around: ZZZ does not have a reroll or transmute system for discs. You can't take a finished disc and re-randomize its substats. What you have instead is a recycle loop.

Dismantle the disc at Bardic Needle, get back Master Copies and some Plating Agents, then tune again with your track, partition, and main stat locked in. It's slower than a true reroll would be, but it's reliable, and with Main Stat Orientation active you're only gambling on substats rather than the whole piece. That's the honest version of "rerolling" in this game, and the discipline part matters more than the mechanic: know when to stop.

Cut your losses

The cheapest filter happens at level 0. Read the substats before you invest anything. If at least 2 of the lines are stats your build wants, it's worth taking to +12. If it's flat HP, flat DEF, and DEF% on a crit carry's slot 4, dismantle it and don't think twice. Upgrading only amplifies what's already there, so a bad disc doesn't grow into a good one.

A reasonable checkpoint system:

1. Level 0: right main stat, at least 2 useful substats. If not, stop.
2. Level 6: two rolls in. Did either land on a stat you care about? If both went to junk, stopping here costs almost nothing.
3. Level 12: the real decision point. Three of five rolls are locked in. If you've got 2+ good lines and they've been favored, push to 15. If it's been a dud, bank it as a +12 and come back later when Plating Agents are plentiful.

Leveling a disc from 12 to 15 is a big chunk of your total investment, so that last push is where most of the wasted Plating Agents in this game go. Make it earn its keep.

Common Disc Drive Mistakes to Avoid

Farming before Inter-Knot 40. The discs just aren't there yet. Every Battery point spent on disc stages at IK 30 is a point that should've gone to ascension materials or skill levels. Wait.

Leveling a wrong main stat because the substats look nice. A CRIT DMG main in slot 4 with perfect-looking substats isn't worth anything if you needed Anomaly Proficiency there. The main stat is the bulk of a disc's value. Wrong main means the piece is off-spec no matter how shiny the rest is, and you're better off vendoring it and tuning a replacement.

Sitting on a hole forever. The opposite mistake. Players hold out for the perfect elemental DMG Bonus in slot 5 for weeks while running a level 1 placeholder. A solid ATK% piece with decent substats gets you 90% of the way there today. Take it and upgrade later when the right one finally drops.

Putting crit discs on supports and stunners. A CRIT Rate / CRIT DMG disc is wasted on Soukaku, who wants Energy Regen and ATK%. Supports don't crit their way to value. Give the good crit pieces to your carries and let the supports run their role stats, even if the disc "feels" too good for a support.

Hoarding junk. Every off-set B-rank and A-rank disc in your inventory is Master Copies and Plating Agents you're not using. Dismantle liberally. The only discs worth keeping are S-ranks with correct main stats, plus anything you might want for a future agent. If you're not going to use it in the next month, break it down.

Forgetting to set the track before tuning. Bardic Needle lets you lock the set, the partition, and the main stat. Tuning with none of those set is just pulling the lever blind. It takes ten seconds to configure and it's the difference between a guaranteed usable piece and a random one.

Sleeping on double drop events. Every so often Area Patrol runs a double drop period. That's four runs a day of natural Battery suddenly producing eight runs' worth of discs. If you've been saving Backup Battery or Ether Battery, this is the moment to spend it. Bank your fuel and cash it in when the event lands.

One last thing on priorities: build one agent at a time. Get your main carry to a full 4+2 with correct main stats before you spread resources across the roster. A single finished character clears more content than three half-built ones, and the supports can wear hand-me-downs for a long time before it actually costs you anything.
