Dialyn is an S-Rank Physical Stun Agent from the Krampus Compliance Authority who made her playable debut in Zenless Zone Zero Version 2.4. Instead of acting as a traditional Stunner who simply stays on-field until an enemy breaks, she combines fast Stun buildup with team buffs, Stun DMG Multiplier increases, and one of the most unusual mechanics in her kit: turning an ally's Chain Attack into an Ultimate. This makes her especially valuable beside Attack and Rupture damage dealers that can turn the extra Ultimate into a much stronger burst window.
Her build is also different from most Stun Agents. Dialyn converts CRIT Rate above 50% into additional Impact through Core Passive: Five-Star Service Hotline, so CRIT Rate is not just a personal damage stat for her. At the same time, her main Stun tools are Energy-hungry EX Special Attacks, meaning a good build must balance CRIT Rate, Energy Regen, and enough offensive stats to make her own Physical attacks worthwhile.
Dialyn Build Overview
The simplest way to build Dialyn is to focus on the parts of her kit that improve both Stun speed and team burst. CRIT Rate should reach at least the 50% threshold required by her Core Passive and King of the Summit, while further CRIT Rate continues to increase her Impact until the conversion reaches its cap. Energy Regen is equally important because Rock, Scissors, and Paper are the main source of her Daze, Positive Reviews, buffs, and Malicious Complaint application.
| Build Category | Recommendation |
|---|---|
| Role | Physical quick-swap Stun / burst enabler |
| Best W-Engine | Yesterday Calls |
| Alternative W-Engines | Hellfire Gears, Steam Oven |
| Best Drive Disc Setup | 4-Pc King of the Summit + 2-Pc Woodpecker Electro |
| Alternative 2-Pc | Shockstar Disco |
| Disk 4 | CRIT Rate |
| Disk 5 | Physical DMG Bonus |
| Disk 6 | Energy Regen > Impact |
| Substats | CRIT Rate / CRIT DMG / ATK% |
| Skill Priority | Core Skill = Special Attack > Chain Attack = Basic Attack > Assist = Dodge |
Do not treat her like a normal Stunner and stack Impact at the expense of everything else. At Core Passive Lv.6, every 1% initial CRIT Rate above 50% grants 2 Impact, up to 100 additional Impact. That makes CRIT Rate unusually efficient because it supports her Core mechanic, activates the full King of the Summit effect, and still improves the damage of her EX Special Attacks.
How Does Dialyn's Kit Work?
Most of Dialyn's gameplay revolves around three connected resources and effects: Positive Reviews, Customer Complaint, and Malicious Complaint. She begins battle with 60 Positive Reviews, gains 0.6 per second during combat, and receives another 7.5 whenever the heavy hit of Rock, Scissors, or Paper connects. Positive Reviews can reach a maximum of 120, and managing them correctly is what lets Dialyn repeatedly create stronger burst windows for her main damage dealer.
Positive Reviews and Ultimate Conversion
Once Positive Reviews reaches 90, Dialyn obtains one Customer Complaint, with only one Complaint held at a time. More importantly, when she has at least 90 Positive Reviews and opens a Chain Attack window through Chain Attack: Welcome Mat, EX Special Attack: Get Lost!, or Quick Assist: Forward Call, the next Agent entering through that window has their Chain Attack upgraded into an Ultimate. When that converted Ultimate is used, Dialyn consumes 60 Positive Reviews.
EX Special Attack: Get Lost! gives her another way to control the timing of this mechanic. It consumes a Customer Complaint instead of Energy and can force a Chain Attack window when the normal conditions are not met, although doing so consumes 90 Positive Reviews. Because this forced route is more expensive, it is usually better to prepare enough Reviews before an enemy is Stunned and use the conversion as part of the normal burst sequence rather than spending the resource early for a smaller payoff.
Rock, Scissors, and Paper
Dialyn's regular EX Special sequence begins with EX Special Attack: Rock. Using Rock changes the next EX Special into Scissors for eight seconds, and Scissors then unlocks Paper for another eight seconds. Each attack costs 25 Energy, so a complete uninterrupted sequence requires 75 Energy, but the eight-second windows mean there is no need to immediately spend all three attacks back-to-back.
The final hit, EX Special Attack: Paper!, is particularly important because it applies Malicious Complaint. When an affected enemy becomes Stunned, the Stun lasts two seconds longer and its Stun DMG Multiplier increases by 30%. This gives the main damage dealer more time to fit high-value attacks and the extra Ultimate created by Dialyn into the same Stun window.
- Rock: Starts the EX sequence and begins building Positive Reviews and Daze.
- Scissors: Continues the sequence and prepares access to Paper.
- Paper: Applies Malicious Complaint, which is the key debuff to have ready before the enemy is Stunned.
- Get Lost!: Uses Customer Complaint rather than Energy and can help control Chain Attack and Ultimate-conversion timing.
Overwhelmingly Positive
Dialyn also becomes a strong team buffer whenever her Additional Ability is active. Using an EX Special Attack or Ultimate gives all squad members Overwhelmingly Positive, increasing their DMG by 40% for 15 seconds. Further EX Special Attacks or Ultimates can extend the effect by 10 seconds when its remaining duration is below 35 seconds, so spacing out the Rock, Scissors, and Paper sequence can maintain the buff while other characters take field time.
The Additional Ability also increases Dialyn's EX Special Attack CRIT DMG by 50%. Her Rock, Scissors, and Paper heavy hits then gain additional damage based on the Specialty of the previous squad member: an Attack Agent contributes damage based on 320% of that Agent's ATK, while a Rupture Agent contributes damage based on 400% of their Sheer Force. This is why squad order matters in both recommended teams below.
What Are Dialyn's Best W-Engines?
Energy generation is a major part of choosing a W-Engine for Dialyn because more Energy directly means more EX Special uses, more Positive Reviews, and faster access to Paper. Her signature is designed around that entire loop, while Hellfire Gears and Steam Oven cover different parts of the same problem. If Yesterday Calls is unavailable, there is no need to abandon the character, but her Energy usage becomes more important to manage.
| W-Engine | Why It Works | Best Use |
|---|---|---|
| Yesterday Calls | Provides 24% CRIT Rate, 1.5 Energy Regen per second while off-field, stacking Daze bonuses from Physical EX Special Attacks, and 30% CRIT DMG for the squad at three stacks. | Best overall |
| Hellfire Gears | Provides 18% Impact, 0.6 Energy Regen per second while off-field, and up to two 10% Impact increases after EX Special Attacks. | Best S-Rank alternative |
| Steam Oven | Provides 50% Energy Regen and gains Impact for stored Energy, with the bonus lingering briefly after Energy is consumed. | Accessible A-Rank option |
Yesterday Calls
Yesterday Calls is the cleanest match for Dialyn's entire kit. Its 24% CRIT Rate makes the 50% Core Passive threshold much easier to reach, while the off-field Energy Regen lets her return to the field with more resources ready for Rock, Scissors, and Paper. Physical EX Special hits can also build up to three Daze-increasing stacks, and reaching the maximum provides the entire squad with 30% additional CRIT DMG for 40 seconds.
The biggest practical advantage is how little the weapon asks you to change the rotation. Dialyn naturally wants to switch in, spend an EX Special, and leave again while her main DPS handles its own resources. Yesterday Calls rewards exactly that pattern, so players who have it can comfortably keep her field time low without starving the next Stun cycle of Energy.
Hellfire Gears
Hellfire Gears is the strongest option to consider if her signature is unavailable but another S-Rank Stun W-Engine is already built. It restores 0.6 Energy per second while Dialyn is off-field and grants 10% Impact after an EX Special Attack, stacking twice. Since her normal rotation already involves repeated EX Specials, maintaining its Impact effect fits naturally into the way she plays.
It does not provide the CRIT Rate or team CRIT DMG of Yesterday Calls, so the Drive Disc build has to carry more of the CRIT burden. Even so, the combination of off-field Energy and Impact makes it a much smoother replacement than an option that only increases raw Stun stats without helping her pay for EX Special Attacks.
Steam Oven
Steam Oven is a practical A-Rank alternative because its 50% Energy Regen helps solve Dialyn's biggest resource problem. Its passive grants Impact for every 10 Energy currently accumulated, stacking up to eight times, and the individual bonuses remain for eight seconds after Energy is spent. The catch is that Dialyn wants to spend Energy often, so its maximum Impact value is not always available when you need it.
If Steam Oven is already upgraded, it is perfectly reasonable to use it rather than investing heavily into another temporary weapon. Focus the rest of the build on CRIT Rate and keep an eye on how much Energy is available before a Stun cycle begins. The build has a lower ceiling than Yesterday Calls, but it still supports the repeated EX usage that makes Dialyn function.
What Are the Best Drive Discs for Dialyn?
4-Pc King of the Summit is the natural core of Dialyn's Drive Disc setup. Its 2-Pc effect increases attack Daze by 6%, while the 4-Pc effect lets a Stun Agent grant 15% CRIT DMG to the whole squad after an EX Special Attack or Chain Attack. If the equipper has at least 50% CRIT Rate, the squad receives another 15%, bringing the set's team CRIT DMG bonus to 30%.
Dialyn already wants more than 50% CRIT Rate for Five-Star Service Hotline, which makes the condition unusually easy to align with her own build. The most straightforward pairing is 2-Pc Woodpecker Electro for another 8% CRIT Rate. Once the CRIT requirement is comfortable through her W-Engine and substats, 2-Pc Shockstar Disco can instead provide 6% Impact.
- 4-Pc King of the Summit: Best general set for combining Daze with a large squad CRIT DMG buff.
- 2-Pc Woodpecker Electro: Preferred when more CRIT Rate is needed to strengthen Five-Star Service Hotline and consistently meet the 50% threshold.
- 2-Pc Shockstar Disco: An alternative when CRIT Rate is already secure and more Impact is more useful than another CRIT Rate bonus.
Best Main Stats and Substats
Disk 4 should use CRIT Rate, as this is the most direct way to feed Dialyn's unusual CRIT-to-Impact conversion. Physical DMG Bonus is the recommended Disk 5 main stat because her attacks deal Physical DMG and she can contribute meaningful damage during her EX sequence. Disk 6 should generally use Energy Regen, with Impact as the alternative when Energy is already comfortable.
For substats, prioritize CRIT Rate, CRIT DMG, and ATK%. Reaching 50% initial CRIT Rate is the first major checkpoint, but there is no reason to stop immediately after crossing it because Five-Star Service Hotline continues granting 2 Impact for every additional 1% CRIT Rate until its 100-point Impact cap is reached. Do not sacrifice Energy consistency just to chase a small amount of extra Impact, though, because missing an EX Special sequence hurts both her Stun output and her support utility.
Which Skills Should You Upgrade First?
Dialyn's Core Skill and Special Attack deserve the first investment because they contain most of what makes her different from other Stunners. Five-Star Service Hotline controls Positive Reviews, Ultimate conversion, the CRIT-to-Impact mechanic, and Malicious Complaint, while her EX Special sequence is one of her main sources of Daze and resource generation. These upgrades should be finished before spreading materials across every part of the kit.
Chain Attack and Basic Attack come next. Her Chain Attack participates directly in Ultimate conversion, while the alternate Basics available after Rock and Scissors give her a useful way to remain active between EX attacks without immediately spending more Energy. Assist and Dodge still have value, particularly because her Assist Follow-Up deals high Daze, but they are lower priorities when materials are limited.
- Core Skill = Special Attack
- Chain Attack = Basic Attack
- Assist = Dodge
How Do You Play Dialyn?
Dialyn works best when treated as a flexible quick-swap Stunner rather than a character who must control the field from the start of the fight until Stun. An early EX Special activates Overwhelmingly Positive, then Rock, Scissors, and Paper can be spaced within their eight-second transition windows while the main DPS builds its own resources. Your real goal is to enter the next Stun with Malicious Complaint already applied and at least 90 Positive Reviews ready for the Ultimate conversion.
When Energy is plentiful, you can move through Rock, Scissors, and Paper quickly. If resources are tighter, use the alternate Basic Attacks available after Rock or Scissors before returning to the EX sequence. This gives Dialyn more active time without immediately consuming another 25 Energy and helps avoid reaching the Stun window with no resources left.
Standard Dialyn Rotation
- Use EX Special Attack: Rock early to activate Overwhelmingly Positive and begin building Positive Reviews.
- Use the alternate Basic sequence or swap to another Agent while preserving the eight-second window.
- Return for EX Special Attack: Scissors, then continue managing Energy and team resources.
- Land EX Special Attack: Paper! before the target is Stunned so Malicious Complaint is active.
- Make sure Dialyn reaches at least 90 Positive Reviews before the main Stun window.
- Use Get Lost!, Welcome Mat, or Forward Call to open the required Chain Attack window.
- Bring in the main damage dealer so their Chain Attack is converted into an Ultimate.
- Use the extended Stun duration to finish the team's remaining Chain Attacks and burst sequence.
The main mistake to avoid is spending Positive Reviews simply because Get Lost! is available. Forcing the Chain window outside the normal Stun sequence costs 90 Reviews and can leave the next important burst without enough resources. Dialyn becomes much more consistent once her Reviews, Energy, and the enemy's Stun gauge are treated as parts of the same rotation instead of three separate systems.
What Are Dialyn's Best Teams?
Dialyn's Additional Ability makes Attack and Rupture damage dealers natural partners, and both recommended teams take advantage of that requirement. Squad order also matters because her Rock, Scissors, and Paper bonus damage checks the Specialty and stats of the previous squad member. Keeping Yixuan or Ye Shunguang immediately before Dialyn therefore allows the EX sequence to use the intended Rupture or Attack scaling.
| Team | Order | Why It Works |
|---|---|---|
| Team 1 | Yixuan + Dialyn + Lucia | Rupture-focused burst team combining extra Ultimates, Sheer Force support, Stun extension, and strong damage buffs. |
| Team 2 | Ye Shunguang + Dialyn + Sunna | Attack-focused team that uses Dialyn's Ultimate conversion to accelerate Ye Shunguang's Enlightened Mind burst while stacking strong Stun-window support. |
Team 1: Yixuan + Dialyn + Lucia
Yixuan + Dialyn + Lucia puts Dialyn between a Rupture carry and a dedicated Rupture-focused Support. Because Yixuan is the previous squad member, Dialyn's Rock, Scissors, and Paper heavy hits gain additional damage equal to 400% of Yixuan's Sheer Force. Yixuan also benefits heavily from extra Ultimate opportunities because spending Adrenaline builds Technique Points for Ultimate: Endless Talisman Suppression, while her Additional Ability restores Adrenaline after a squad member uses an Ultimate.
Lucia completes the team by attacking the same stats that Yixuan wants. Darkbreaker can provide up to 900 additional Sheer Force based on Lucia's initial Max HP, and her Additional Ability adds another 30% CRIT DMG when the team contains a Rupture or Stun Agent. Ether Veil: Wellspring also increases all squad members' Max HP by 5%, which directly helps Yixuan because her Core Passive converts Max HP into Sheer Force.
In practice, establish Lucia's support effects and let Yixuan build Adrenaline and Technique Points while Dialyn rotates through her EX Specials. Paper should land before the target enters Stun, and Dialyn should have 90 Reviews ready at that point. Converting Yixuan's Chain Attack into an Ultimate gives her another high-value burst action while Malicious Complaint extends the Stun by two seconds and raises the Stun DMG Multiplier by 30%.
Team 2: Ye Shunguang + Dialyn + Sunna
Ye Shunguang + Dialyn + Sunna uses the same idea with an Attack carry. Placing Ye Shunguang directly before Dialyn makes the additional damage on Rock, Scissors, and Paper scale from 320% of Ye Shunguang's ATK. More importantly, an Ultimate gives Ye Shunguang six Qingming Sword Force and allows her to enter or continue the Enlightened Mind portion of her kit, so Dialyn's Chain-to-Ultimate conversion directly improves her access to the state where her strongest attacks become available.
Sunna adds another layer of Stun-window support. Angelic Chord-ination grants the squad ATK based on 30% of Sunna's initial ATK, up to 1,050, while Ether Veil: Delusion Reprise supplies an additional 50 ATK. Her Additional Ability can also increase the target's Stun DMG Multiplier by 30% when characters inside the Ether Veil attack it, giving this composition several ways to make Ye Shunguang's burst window more valuable.
The rotation should prepare Sunna's buffs, build Ye Shunguang's resources, and weave Dialyn's Rock-to-Paper sequence into the downtime before Stun. Once Malicious Complaint is applied and Dialyn reaches the required Positive Reviews, use her conversion to send Ye Shunguang into an Ultimate rather than an ordinary Chain Attack. The extra Stun duration then gives her more room to spend Qingming Sword Force and complete the Enlightened Mind sequence without rushing every input.
Are Dialyn's Mindscapes Worth It?
Dialyn is already functionally complete at M0 because the Ultimate conversion, Malicious Complaint, Overwhelmingly Positive, and CRIT-to-Impact conversion are all part of her base kit. Her early Mindscapes mainly improve how often those mechanics can be used and how much team damage they provide. Players choosing between more copies and other upgrades should therefore view M1 and M2 as enhancements rather than requirements.
- M1 – Boundless Hospitality: Increases Positive Review generation by 16% and lets characters ignore 15% of enemy All-Attribute RES while Overwhelmingly Positive is active. This is a strong early stopping point because it improves both resource comfort and team damage.
- M2 – 24/7 Hotline: Adds another 20% Stun DMG Multiplier to enemies affected by Malicious Complaint and increases all damage dealt to those targets by 15%. This is the most attractive early Mindscape for players focused on maximizing her team support.
- M3 / M5: Increase Basic Attack, Dodge, Assist, Special Attack, and Chain Attack levels by two.
- M4 – The Past Never Fades: Restores 20 Energy when entering combat and grants Dialyn 500 ATK while Overwhelmingly Positive is active, improving both opening comfort and personal damage.
- M6 – Truth: Converted-Ultimate allies gain Aftertone, allowing their attacks to trigger additional Physical DMG from Dialyn equal to 480% of her ATK once per second, up to 12 times.
M1 is the easier value pick because faster Positive Review generation directly smooths the mechanic that controls her Ultimate conversions. M2 pushes the Stun burst much further, especially for teams that already concentrate most of their damage into the window created by Paper. M6 adds substantial personal follow-up damage, but it is a luxury endpoint rather than something needed for the character to perform her main Stun and support role.
Dialyn Upgrade Materials
Fully preparing Dialyn requires both standard Physical skill materials and Stun promotion materials. Her Core Passive and Special Attack should take priority if resources are limited, so there is no need to immediately max every Basic, Dodge, and Assist skill before the core build is functional. The complete material list supplied for her Lv.60 build and skill progression is:
- 3,705,000 Denny
- 25 Basic Physical Chip
- 75 Advanced Physical Chip
- 250 Specialized Physical Chip
- 4 Basic Stun Certification Seal
- 32 Advanced Stun Certification Seal
- 30 Buster Certification Seal
- 5 Hamster Cage Pass
- 9 Exuvia of Refinement
- 60 Higher Dimensional Data: Stealth Phantom
If materials are tight, reach Lv.60 and finish the important Core Skill upgrades before trying to perfect every lower-priority talent. Her value comes from Five-Star Service Hotline, the EX Special sequence, and creating better Stun bursts for the rest of the squad. Those systems should be working properly before spending the last batch of resources on smaller Basic, Dodge, or Assist improvements.
Dialyn Build FAQ
How much CRIT Rate does Dialyn need?
Dialyn should have more than 50% initial CRIT Rate because both her Core Passive and the full King of the Summit effect benefit from crossing that threshold. At Core Passive Lv.6, every additional 1% CRIT Rate above 50% grants 2 Impact until the bonus reaches its 100-point cap. This makes CRIT Rate one of her most useful stats rather than a secondary damage-only choice.
Does Dialyn need Yesterday Calls?
No. Yesterday Calls is her strongest W-Engine because it combines CRIT Rate, off-field Energy Regen, Daze, and squad CRIT DMG in one package, but Hellfire Gears and Steam Oven can both support her core rotation. Without the signature, pay closer attention to Energy and use her alternate Basic Attacks between EX Specials when necessary instead of trying to spam the full Rock, Scissors, Paper sequence every time she appears.
Should Dialyn use Energy Regen or Impact on Disk 6?
Energy Regen is the safer general choice because her EX Special Attacks drive nearly every important part of the kit, including Daze, Positive Reviews, Overwhelmingly Positive, and Malicious Complaint. Impact can work when the rest of the build already provides enough Energy, but stacking more Impact does little if Dialyn reaches the next Stun cycle without enough Energy to use her EX sequence. Consistent rotations should come before a small theoretical Stun increase.
Why does team order matter for Dialyn?
Her Additional Ability gives Rock, Scissors, and Paper extra damage based on the Specialty of the previous squad member. If that character is an Attack Agent, the extra hit scales from 320% of their ATK; if it is a Rupture Agent, it scales from 400% of their Sheer Force. This is why the recommended orders keep Yixuan before Dialyn in the first team and Ye Shunguang before Dialyn in the second.
