The 2.7 update for Zenless Zone Zero brings game-changing signature W-Engines for Cissia and Nangong Yu, effectively shifting the meta for all agent specialties. Nangong Yu’s Neon Fantasies has redefined the Stunner category with its unique Anomaly Mastery scaling, while Cissia’s Serpentine Seeker establishes a new benchmark for Attack-focused agents.
ZZZ 2.7 W-Engine Tier List: Quick-Reference Rankings
S-Tier W-Engines dominate their respective roles by offering superior passive bonuses, reliable activation triggers, and excellent synergy across various team compositions. Data from community testing indicates that S-tier gear typically yields a 15-25% damage boost over A-tier substitutes when their passives are fully utilized.

Always match the W-Engine specialty to the agent to unlock passive effects; otherwise, you are limited to base stats alone. Refinement levels range from R1 to R5. While most S-tier weapons are highly effective at R1, reaching R5 can boost passive performance by 20-40%.
New 2.7 W-Engines: Nangong Yu & Cissia Signatures
Patch 2.7 introduces two signature weapons that immediately secure their place at the top of the meta. To get the most out of these, players must focus on specific team-building strategies.
Nangong Yu Signature: Neon Fantasies
Neon Fantasies (S-Rank Stunner) offers 713 Base ATK and a 30% Anomaly Mastery boost. At R1, the passive provides +90 Anomaly Proficiency, and Ether DMG triggers a 15% team-wide damage buff for 40 seconds, which can stack twice. This is the first Stunner W-Engine built for hybrid daze and anomaly playstyles.
While highly effective, Neon Fantasies is not strictly required. It offers a 25-30% performance gain over options like Hellfire Gears. For F2P players, Steam Oven R5 or Precious Fossilized Core R5 are viable, though they lack the Anomaly Mastery stat.
Cissia Signature: Serpentine Seeker
Serpentine Seeker (S-Rank Attack) provides 713 Base ATK and 60% Energy Regen. Its R1 passive grants a 25% CRIT Rate bonus, and consuming 20+ Energy triggers DEF ignore for Electric DMG for up to 30 seconds. It is perfectly tuned for Cissia’s Energy-dependent kit.
Serpentine Seeker outperforms other options by 20-25% due to its precise stat alignment. A-rank alternatives like Drill Rig - Red Axis R5 are functional but lack the essential Energy scaling that defines her optimal rotation.
Best Attacker W-Engines: Full Tier Breakdown
Attacker W-Engines focus on maximizing CRIT scaling, damage output, and resistance penetration.
S-Tier Attackers
Heartstring Nocturne remains the gold standard with its 50% CRIT DMG and Fire RES ignore. Serpentine Seeker is S-tier for Electric-focused teams, while Severed Innocence is a versatile choice thanks to its general CRIT scaling.
Best F2P Attacker Options
- Brimstone R5 - Battlepass weapon featuring high Attack scaling
- Drill Rig - Red Axis R5 - Grants 80% Electric DMG following EX or Chain attacks
- Marcato Desire R5 - Provides an ATK bonus when anomaly conditions are met
Drill Rig - Red Axis R5 is a standout for Electric Attackers, delivering an 80% Electric DMG bonus when rotations are executed correctly.
Best Stunner W-Engines: Maximize Daze & Chain Windows
S-Tier Stunners
Neon Fantasies leads the pack with its exclusive Anomaly Mastery. Hellfire Gears is excellent for reliable Impact scaling via EX attacks, and Ice-Jade Teapot provides a strong mix of Energy Regen and Impact.
F2P Stunner Picks
- Steam Oven R5 - A craftable option that converts Energy into Impact
- Precious Fossilized Core R5 - Focuses on pure daze scaling
- Hellfire Gears - Provides S-tier results if you happen to pull it
Steam Oven R5 is the top F2P choice, effectively turning Energy usage into an Impact bonus.
Best Anomaly W-Engines: Disorder & DoT Optimization
S-Tier Anomaly
Weeping Cradle is the top choice due to its hit-based damage amplification, which scales impressively with refinement. Rainforest Gourmet is ideal for Burn/Shock synergy, while Fusion Compiler offers great overall utility.
Weeping Cradle is superior to most alternatives at any refinement level thanks to its potent damage amplification mechanics.
Best Support W-Engines: Buff Uptime & Team Utility
S-Tier Support
Elegant Vanity is highly valued for converting Energy into team-wide damage buffs. Weeping Cradle offers damage amplification through hit-based triggers, and Unfettered Game Ball is excellent for utility-focused builds.
Elegant Vanity is the primary F2P priority for those looking to boost team performance via standard pulls.
W-Engine Specialty Matching: The Rule You Cannot Ignore
You must match the W-Engine specialty to the agent's role to activate its passive. If they don't match, you only receive the base ATK and substats. Even an S-tier weapon will underperform compared to a matched A-tier weapon if the specialty type is wrong.
Mismatched W-Engines lose their entire passive effect, resulting in a 15-30% performance drop. This penalty is more severe for signature weapons, which rely heavily on their unique passives.
W-Engine Refinement Guide: Is It Worth It?
Refining a W-Engine enhances its passive, but it requires duplicate copies. Percentage-based passives often see their effectiveness double, whereas flat bonuses show minimal gains. For most players, expanding your collection is more valuable than maxing out a single weapon.
Always prioritize leveling up your weapons first, as Base ATK scaling is guaranteed. A level 60 R1 weapon will consistently outperform a level 1 R5 weapon.
Which W-Engines Scale Best With Refinement?
Percentage-based passives are the best candidates for refinement: Weeping Cradle and Elegant Vanity show significant growth from R1 to R5. Conversely, flat bonus passives scale poorly, making weapons like Steam Oven less rewarding to refine.
Team-Context Adjustments: When Rankings Shift
W-Engine efficiency depends heavily on your team composition. Teams centered on Anomaly damage prioritize different stats than those focused on burst windows.
Neon Fantasies becomes essential in Anomaly-heavy teams where the team damage buff synergizes with frequent Disorder triggers. Similarly, Drill Rig - Red Axis gains value in Electric-focused teams where its 80% Electric damage bonus can be triggered consistently.
Should You Pull the W-Engine Banner in ZZZ 2.7?
Most players should prioritize character banners over the W-Engine banner. For the majority of content, pulling a new character provides 50-100% more account value than the 15-30% boost offered by a W-Engine.
The W-Engine banner features an 80-pull pity with a 50/50 rate-up, meaning you may need up to 160 pulls to guarantee the featured weapon. Plan your resources accordingly.
F2P players should avoid this banner unless they are dedicated mains of Nangong Yu or Cissia. It is generally better to build up A-tier and craftable weapons while saving Polychrome for new characters.
