Zenless Zone Zero (ZZZ) is a fast-paced urban RPG where your Agents’ strength depends not only on skill but also on how efficiently you gather resources. From credits and EXP chips to Hollow materials and rare Drive Discs, every system in the game is tied to resource farming. The problem is that energy is limited, resources are scarce, and poor planning can easily stall your progression.

That’s why mastering how to farm resources and progress fast is crucial for both beginners and veterans. This guide explores farming strategies across daily missions, Hollow expeditions, and long-term progression paths, showing you how to get the most out of your time in New Eridu.

Understanding the Resource Economy in ZZZ

Before farming efficiently, you need to understand what resources exist and how they interact with Agent progression.

Core Resource Categories

  • Credits – The universal currency, used for almost every upgrade.
  • EXP Chips – For leveling Agents.
  • Ascension Materials – Unlock level caps and Agent power.
  • Skill Books – Used to upgrade combat abilities.
  • W-Engine & Drive Disc Materials – Strengthen weapons and gear.

Why Resource Management is Key

Unlike some gacha RPGs, ZZZ is stingy with energy and drops. This means you can’t farm endlessly. Every action costs, and planning ahead saves weeks of grind.

Daily Commissions: The Fastest Base Farming

Daily Commissions are your bread and butter for consistent farming. Completing them should be your first action every day.

Benefits of Daily Commissions

  • Reliable credits and EXP items.
  • Small amounts of premium currency.
  • Helps build routine progression.

How to Optimize Them

  • Finish all commissions daily for steady passive growth.
  • Stack rewards by pairing commission runs with material farming.
  • Use weaker Agents in easy missions to train them while still farming.

How to Farm Hollow Expeditions Efficiently

Hollow expeditions are the heart of farming in ZZZ. They give essential materials but drain your limited energy.

Route Planning

Each Hollow has multiple nodes offering combat, resources, or healing. Plan routes carefully to maximize material gain while conserving stamina.

Tips for Hollow Farming

  • Save Ultimates for mini-bosses to clear faster.
  • Target specific nodes that drop the materials you need most.
  • Don’t overfarm low-level Hollows—move up once your team can handle harder tiers.

Credit Farming: How to Avoid Shortages

Credits are deceptively scarce in ZZZ. Almost every upgrade drains them, and running out halts progress.

Sources of Credits

  • Daily commissions.
  • Specific Hollow nodes.
  • Special events or side quests.

Credit Farming Tips

  • Focus spending on your main Agents, not every unit.
  • Avoid wasting credits enhancing Drive Discs with poor stat rolls.
  • Farm dedicated Credit stages when you hit bottlenecks.

Farming EXP Chips for Agent Growth

Leveling is one of the first bottlenecks, as EXP chips run out quickly.

Where to Get EXP Chips

  • Daily missions.
  • Specific Hollow farming routes.
  • Events and log-in rewards.

Efficiency Tips

  • Don’t max every Agent—focus on your primary DPS and key supports.
  • Save higher-level EXP chips for rarer Agents to avoid waste.
  • Farm during double-drop events to maximize return.

How to Farm and Use Ascension Materials

Ascension materials are essential for breaking Agent level caps.

Material Sources

  • Hollow expeditions.
  • Weekly boss drops.
  • Event stores or exchanges.

Farming Strategies

  • Focus on one DPS first to avoid resource dilution.
  • Farm extra materials for future upgrades if you know your next priority Agent.
  • Use planning tools or community drop charts to avoid wasted energy.

Drive Discs and W-Engines: Long-Term Farming

These gear systems offer huge stat boosts, but farming them wrong wastes time.

Drive Disc Farming

  • Don’t farm too early—low-level sets get replaced fast.
  • Prioritize ATK %, Crit Rate, and Crit Damage rolls for DPS.
  • Upgrade only high-quality sets with good stat lines.

W-Engine Materials

  • Focus upgrades on one main W-Engine per role.
  • Don’t over-upgrade weapons for Agents you won’t use long-term.
  • Farm upgrade materials alongside daily credit runs for efficiency.

Energy Management: The Key to Faster Progression

Energy is the most important limiter in ZZZ farming. Mismanagement slows progression dramatically.

Energy Tips

  • Never let energy cap out—log in to spend it regularly.
  • Prioritize farming scarce materials over common ones.
  • Save energy for farming during events with double-drop rewards.

Long-Term Energy Strategy

Use energy daily, even if you can’t play much—set short Hollow runs to keep resources flowing.

Weekly Bosses and Limited Events

Weekly bosses and time-limited events are your highest-value farming opportunities.

Weekly Bosses

  • Drop rare ascension and skill upgrade materials.
  • Have weekly caps, so missing them slows progression permanently.

Events

  • Often provide bonus farming rewards like double credits.
  • Focus your farming during events to maximize long-term efficiency.

Mistakes to Avoid in Farming

Efficient farming is as much about avoiding mistakes as it is about grinding.

Common Farming Mistakes

  • Overfarming weak Hollows – wastes energy.
  • Spreading resources across too many Agents – weakens your team.
  • Enhancing poor Drive Discs – drains credits and materials.

How to Avoid Them

  • Always plan upgrades ahead of time.
  • Prioritize one carry DPS and their best W-Engine before diversifying.
  • Treat energy as your most valuable currency, not just a timer.

Conclusion

Farming resources and progressing fast in Zenless Zone Zero isn’t about endless grinding—it’s about strategy, prioritization, and planning. By focusing on daily commissions, optimizing Hollow expeditions, managing credits and EXP wisely, and targeting ascension materials for your main DPS first, you can avoid common traps and steadily power up your team.

Use energy efficiently, don’t spread resources too thin, and always save farming for double-reward events when possible. With these strategies, you’ll keep your Agents strong, your resources flowing, and your progression smooth, making you always ready to face the toughest Hollows in New Eridu.
