ZZZ Drive Disc Farming — Where to Farm & When to Start Optimizing | Zenless Zone Zero

There are 3 main sources:

• Routine Cleanup (Combat Simulation): your main Battery sink for discs, costing 60 Battery per run, and you can skip the fight to grab rewards instantly.
• Notorious Hunt (weekly boss): 3 free runs each week, then 60 Battery per extra run. This is where you find higher-quality discs.
• Tuning at the video store: use Master Tapes / Hi-Fi Master copies to craft discs from the set you actually want.

S-rank discs only drop from Level 40+ enemies, with a much higher rate from Level 60 foes.

The golden milestone is Inter-Knot Level 40. Here's why:

• S-rank discs finally drop reliably (Level 40+ enemies).
• It unlocks Advanced Tuning — craft discs and guarantee an S-rank disc in the set you want (3 Hi-Fi Master copies per pull).

Many Japanese guides even suggest waiting until Inter-Knot Level 50 to unlock Routine Cleanup Lv.60 — which gives the best substat quality — before going all-in. In short: Level 40 to begin, Level 50 to truly grind.

Tip: the main-stat targeting feature unlocks once your video store reaches Level 3, letting you aim the exact slot and main stat you need.

Because slots 1–3 have only one fixed main stat each, they're the best slots to roll substats on. Slots 4, 5, 6 have many possible main stats, so use the targeting feature there to avoid wasting runs.

• Lock in the correct set for your Agent first, then worry about substats.
• Only level a disc once its main stat is correct — leveling blindly wastes resources.
• Don't rush to disassemble strong S-rank discs: many are usable right away without further tuning.

• Optimizing too early: below Inter-Knot 40, S-rank discs don't drop reliably, so grinding early is a waste. Level your Agents and W-Engines first.
• Burning Battery randomly: each Routine Cleanup run costs 60 Battery — pick the exact set you need before grinding.
• Hoarding junk discs: disassemble off-set B/A discs for resources instead of clogging your inventory.

Every Drive Disc has 4 substats, and each one can be "rolled" (upgraded) up to 5 times as you enhance it. Before deciding to keep or discard a disc, look at whether its substats actually serve your build: DPS builds usually want Crit Rate/Crit DMG and ATK%, Anomaly builds want Anomaly Proficiency, and Support builds want Impact or Energy Regen depending on their role.

A quick rule of thumb: a disc worth enhancing should already have at least 2 of its 4 substats matching what your build needs — enhancing only amplifies existing lines, it never adds new ones. If all 4 substats are useless to you, disassemble it for materials even if the main stat looks great, no matter how tempting it is to keep.

A common newcomer mistake is dumping Battery into a disc with a gorgeous main stat but substats that don't serve the build — the real output ends up lower than a disc with an average main stat but substats that actually fit.

Both main farming sources reset weekly, and neither carries over if you skip a week: Notorious Hunt grants 3 free clears per week (no Battery cost), each dropping high-tier discs plus upgrade materials directly; Routine Cleanup (Combat Simulation) has no run limit but costs 60 Battery per run, and Battery regenerates over time, which naturally caps how much you can farm per day.

A sensible weekly order: clear your 3 free Notorious Hunt runs first since that's a capped free resource, then spend any leftover Battery on Routine Cleanup. If you miss logging in for a week, those 3 Notorious Hunt clears are simply lost, not banked — so if your play time is limited, spend it here first.

Drive Discs are organized into 6 equipment slots, and each set usually grants a 2-piece bonus (equip 2 discs from the same set) with some sets also offering a stronger 4-piece bonus (equip all 4). Since every Agent wears 6 discs total, the most common loadout is one 4-piece set plus one 2-piece set (using 4+2 slots), or if you don't have enough discs yet, three different 2-piece sets as a stopgap.

When you're just starting out, don't force a 4-piece set right away — prioritize grabbing any disc with the right main stat and substats first, mixing sets 2-2-2 style for stable early damage. Only once you have a decent stockpile should you chase a full 4-piece set for the bigger bonus, since hunting the exact 4-piece combo takes noticeably longer to farm than filling out 2-piece sets.

With limited resources early on, the most efficient approach is to give your best discs to one main DPS Agent first, since the team's damage output largely rides on that single character. Only once your main DPS is set (full 4-piece set, matching substats) should you start sharing spare discs with support or secondary DPS Agents.

Support/Stun Agents generally need much less from their discs — just enough HP/DEF to survive and the right role-specific stat (Impact for stunning, Energy Regen for faster energy), not a Crit-chasing build like a DPS. So don't waste a beautiful Crit Rate/Crit DMG disc on a support Agent just because it happens to be sitting in your inventory.
