Zenless Zone Zero W-Engine Guide: How to Get, Upgrade & Modify Efficiently

If you want your agents to reach their full potential in Zenless Zone Zero, you can’t ignore W-Engine—it’s the cornerstone of boosting combat power. W-Engine directly determines your agents’ DPS ceiling, anomaly chain damage, and how often support skills can be used. With the right W-Engine bonuses (like attribute DMG%, CRIT, or anomaly mastery), you can turn an average team into a top-tier squad that crushes high-difficulty Void dungeons and Expert Challenge.
This definitive guide from LootBar will help you skip the grind and build the best W-Engine setups efficiently. And if you want to enhance your gameplay by topping up or getting in-game resources securely at discounted rates, LootBar is your go-to platform. Trusted by thousands of gamers worldwide for its safe, fast, and budget-friendly top-up services, LootBar lets you top up Zenless Zone Zero effortlessly to speed up your W-Engine build. Let’s dive in.

How to Obtain W-Engines Efficiently

First, let’s clarify when you can unlock the W-Engine system: You’ll get access after completing Chapter 3: “The Mystery of the Engine” (when your Inter-Knot Level is around 30–32). Below are 4 reliable farming methods, sorted by efficiency and target specificity—each with clear pros and cons to help you decide quickly what to focus on.

1. Engine Workshop

Engine workshop is the main way to get W-Engines, available 3 times a day. Each run costs 40 Battery Charge, and the difficulty level directly affects the quality of drops and farming efficiency.
What it includes (difficulty tiers):

• Normal (Level 30+): Drops Common or Rare W-Engines. Pros: Low difficulty, fast to clear. Cons: No Epic W-Engines. How to use/best for: Early-game farming of basic materials when your team is still weak.
• Hard (Level 45+): 30% chance to drop Epic W-Engines. Pros: Balanced difficulty and rewards. Cons: Takes 10–15 minutes per run. How to use/best for: Mid-game progression—this is your main source of Epic W-Engines once your team is strong enough.
• Nightmare (Level 60+): 50% Epic drop rate + 10% chance for Legendary fragments. Pros: Highest yield of high-quality W-Engines/fragments. Cons: Requires a strong team (high combat power). How to use/best for: Late-game priority—you must focus on this to get top-tier gear for endgame content.

 

2. Event Exchange

Official limited-time events like version updates or collaborations give out event tokens. You can exchange these tokens for Epic W-Engines or Legendary fragments directly. It includes Tokens earned from daily event tasks, challenge stages, or event quests—all exchangeable for fixed W-Engine rewards.
This method is super friendly for you—you don’t need to spend any Battery Charge, and the rewards are 100% targeted, meaning you can directly exchange for the Epic W-Engines or Legendary fragments you want without relying on RNG luck. But here’s a little reminder: these events are time-limited, so you can’t get these rewards once the event ends. The best strategy is to stick to completing the daily event tasks consistently; the event tokens are stackable, so you can save them up slowly and exchange for the Epic W-Engines you need steadily—no more worrying about bad luck with drops!

3. In-Game Shop

You can buy W-Engine Supply Boxes in the Logistics Store using Monochrome (since there are no Star Rainbow Coins in ZZZ). What it includes (two main boxes):

• Monthly Limited Box (100 Monochrome): Guarantees 1 Epic W-Engine.Must-buy for core players—it’s cost-effective and has no RNG, so you can plan your Epic W-Engine gains.
• Daily Refresh Box (20 Monochrome): Random Common or Rare W-Engine. Only buy this if you’re short on early-game materials (Common/Rare). It’s not worth buying long-term because the rewards are low-value.

Farming Tips

These tips are tailored to help you solve the most common problems in W-Engine farming , letting you skip the grind and progress faster.

• Battery Charge replenishment: Top up Zenless Zone Zero via LootBar to get Monochromes—exchange for Battery Charge in the shop for extra Engine Workshop runs. LootBar’s 3-minute instant top-up avoids grind gaps.
• Material recycling: Dismantle excess W-Engines: Common=1 W-Engine Part, Rare=3 High-Grade Parts, Epic=5 Supreme Parts (critical for advanced modification).
• Material farming shortcut: High-level Void dungeons drop Attribute Crystals (1–2 per clear); Legendary Crystals are only available in Expert Challenge (unlocked at Elite Proxy).

W-Engine Matching

The basics of W-Engine matching is: each agent can equip 3 W-Engines. If you equip 3 W-Engines of the same attribute, you’ll trigger a 20% attribute damage boost—this is the optimal setup, because mixed sets will waste this valuable bonus.

Below is a role-specific matching guide (with real agent examples) to help you choose the right W-Engines. It covers what type of W-Engine to pick for each role, the must-have effects, recommended sets, and which agents benefit most.

Agent Role	Core W-Engine Type	Must-Have Effects	Recommended Set	Top Agent Examples
Attack (DPS)	Offensive Type	Attribute DMG%, CRIT Rate/DMG, PEN Ratio	3x Offensive Type (max attack boost)	Billy (Electric)
Anomaly Output	Anomaly Type	Anomaly Proficiency, Anomaly Mastery	3x Anomaly Type (strengthens chain damage)	Lycaon (Freezing), Billy
Defensive	Defensive Type	HP%, DEF%, Damage Reduction	2x Defensive + 1x Functional (survival + energy)	Hugo, Nicole
Support	Functional Type	Energy Regen, Team ATK Boost, CD Reduction	3x Functional Type (max support frequency)	Anby, Emma

Critical rule: DPS agents prioritize Attribute DMG% over ATK%—a 30% Fire DMG boost outperforms a 50% ATK boost for elemental builds.

W-Engine Modification

Modifying the system itself isn’t complicated, but the required materials and how you obtain them often determine the pace of your progress.

Modification Level	Materials Needed	Material Acquisition Paths	Priority (Who to Modify First)
Basic (1–3)	10 W-Engine Parts + 50k Tennys	Dismantle Common W-Engines; Tennys from daily quests	All core agents (quick boost)
Intermediate (4–6)	8 High-Grade Parts + 5 Attribute Crystals + 150k Tennys	Dismantle Rare W-Engines; High-level Void dungeons	Main DPS/anomaly agents
Advanced (7–10)	5 Supreme Parts + 3 Legendary Crystals + 300k Tennys	Dismantle Epic W-Engines; Expert Challenge	Only Legendary W-Engines (worth investment)

At the same time, it’s important to follow key renovation guidelines and avoid investing excessive resources during the transition phase. This will not only prevent unnecessary detours but also ensure that limited resources are truly used on the most worthwhile renovation points.

1. Lock core effects first: For DPS, lock Attribute DMG%/CRIT; for anomaly agents, lock Anomaly Proficiency—refreshing without locking deletes key bonuses.
2. Abandon low-potential W-Engines: If a W-Engine hasn’t rolled 2+ beneficial substats by Level 9 (e.g., no CRIT for DPS), dismantle it—upgrading further wastes materials.
3. Prioritize core stats: For DPS, upgrade Attribute DMG% > CRIT Rate > CRIT DMG; for support, upgrade Energy Regen > Team ATK Boost.

 

Common Mistakes

1. Blindly chasing Legendary: An Epic W-Engine with perfect substats outperforms a poorly rolled Legendary—don’t waste materials on bad Legendaries.
2. Dismantling duplicate Rares: Rare W-Engine fragments are required to synthesize Legendaries —only dismantle excess duplicates.
3. Ignoring set effects: Mixing Offensive + Anomaly W-Engines sacrifices the 20% attribute boost—never do this for core DPS/anomaly agents.
4. Over-modifying early-game W-Engines: Don’t spend Supreme Parts on Rare W-Engines—save for Epic/Legendary ones.

Conclusion

Mastering W-Engine farming and modification boils down to three core steps: prioritize Nightmare Engine Workshop for high-quality drops, match W-Engines to agent roles (3x same attribute=optimal), and focus modification on core agents. This turns mid-tier squads into high-difficulty challenge-clearing teams.
