💿 Zenless Zone Zero Drive Disc Guide: How to Farm and Roll Perfect Stats

In Zenless Zone Zero, Drive Discs represent the foundational gear system dictating whether your Agent unleashes devastating combat potential or struggles against Hollow monstrosities. Operating as New Eridu's version of artifact and relic gear, Drive Discs provide massive offensive, defensive, and tactical stat bonuses.

Because securing optimal Drive Discs involves multiple layers of RNG across both Main Stats and Substats, entering the farming loop without a clear strategy can quickly exhaust your Battery Charge. Here is the ultimate breakdown on how to master the Drive Disc system, identify god-tier rolls, and efficiently build every Agent in your roster.

🧩 1. Understanding Drive Disc Slots: Fixed vs. Variable Main Stats

Every Agent equips a total of six Drive Discs across designated numerical partitions. The slots are divided into two distinct mechanics:

🔹 Partitions 1, 2, and 3 (Fixed Main Stats)

• Slot 1: Always rolls Flat HP.

• Slot 2: Always rolls Flat ATK.

• Slot 3: Always rolls Flat DEF.

Because these three slots feature static main stats, finding a usable piece is relatively easy. Your primary goal when farming Slots 1, 2, and 3 is purely chasing ideal substat combinations.

🔹 Partitions 4, 5, and 6 (Variable Main Stats)

• Slot 4: Can roll CRIT Rate, CRIT DMG, ATK%, HP%, DEF%, or Anomaly Proficiency.

• Slot 5: Can roll ATK%, HP%, DEF%, Attribute DMG Bonus (Physical, Fire, Ice, Electric, Ether), or Anomaly Mastery.

• Slot 6: Can roll ATK%, HP%, DEF%, Anomaly Mastery, Impact%, or Energy Regen%.

Partitions 4 through 6 define an Agent's build trajectory. Most of your farming runs and tuning resources will be dedicated to landing the correct main stat on these three specific slots.

🎯 2. Substats: The Anatomy of a "God Roll"

Each Drive Disc can possess up to four secondary substats. A piece upgrades its substats at enhancement milestones: +3, +6, +9, +12, and +15 (offering up to five stat upgrades in total).

• Available Substat Pool: CRIT Rate, CRIT DMG, ATK / ATK%, HP / HP%, DEF / DEF%, Anomaly Proficiency, and PEN Ratio / Flat PEN.

• The Perfect "God Roll": A disc that matches the Agent's required Main Stat, begins with three or four relevant offensive substats, and hits desirable substat upgrades at every enhancement milestone without rolling into dead stats like Flat DEF.

📍 3. Key Drive Disc Farming Locations

Maximize your daily stamina expenditure by focusing on dedicated farming avenues:

• Routine Cleanup & Hollow Zero: The primary farming grounds for target set pieces and weekly milestone rewards.

• Shiyu Defense: Provides high-rarity Drive Disc crates and currency upon completing bi-weekly seasonal challenge nodes.

• Notorious Hunt: High-tier boss encounters drop specific disc sets with improved tuning yields.

• Music Store Tuning (Bardic Needle): Allows Proxies to dismantle unwanted discs and dismantle them into Master Copies to craft targeted sets and specific slot partitions.

🛠️ 4. Efficient Tuning and Upgrading Strategies

• Filter and Lock Early: Utilize in-game inventory filters to sort discs by set, slot, and desirable main stats. Lock high-potential pieces immediately and mark unusable main stats as scrap.

• Evaluate Initial Substats: Avoid spending valuable Plating Agents on discs that roll multiple dead substats at Level 0. Look for at least two relevant substats before investing materials.

• Upgrade Incrementally (+3 Testing): Level up a promising disc to +3 or +6 first. If initial upgrade rolls land on unwanted stats, halt upgrades immediately to prevent resource waste.

• Recycle High-Level Fodder: Discs that roll poorly during mid-level enhancements can be fed directly into new candidate pieces, transferring a significant portion of their accumulated EXP.

👥 5. Target Stat Priorities by Agent Combat Role

• Attack DPS (Direct Damage Dealers):

  • Slot 4: CRIT Rate or CRIT DMG

  • Slot 5: Attribute DMG Bonus%

  • Slot 6: ATK%

  • Substat Priority: CRIT Rate, CRIT DMG, ATK%, PEN Ratio

• Anomaly DPS (Attribute Buildup Specialists):

  • Slot 4: Anomaly Proficiency or ATK%

  • Slot 5: Attribute DMG Bonus% or Anomaly Mastery

  • Slot 6: Anomaly Mastery or ATK%

  • Substat Priority: Anomaly Proficiency, ATK%, PEN Ratio

• Stun Specialists (Daze Accumulators):

  • Slot 4: CRIT Rate/DMG or ATK%

  • Slot 5: Attribute DMG Bonus%

  • Slot 6: Impact% (Mandatory for Daze scaling)

  • Substat Priority: Impact%, Energy Regen%, ATK%

• Support & Sustain Units:

  • Slot 4 through 6: Tailored to scaling requirements (Energy Regen%, HP%, DEF%, or ATK% for buff-sharing).

⚖️ 6. The Golden 1:2 CRIT Ratio Benchmark

For traditional Attack-based damage dealers, maintain the standard 1:2 CRIT Rate to CRIT DMG ratio (such as 60% CRIT Rate to 120%+ CRIT DMG). This distribution ensures optimal mathematical damage output across prolonged combat encounters by balancing reliability with burst ceiling.

🚫 Common Pitfalls to Avoid

• Rushing 4-Piece Sets with Wrong Main Stats: A complete set bonus will never compensate for an incorrect main stat on Slots 4, 5, or 6.

• Overlooking PEN Ratio: Penetration stats ignore high enemy defense pools, providing massive value in high-tier Shiyu Defense stages.

• Upgrading Every Dropped Disc: Blindly leveling mediocre gear drains Dennies and Plating Agents rapidly; maintain strict filtering standards.
