What Makes Dialyn Special
Dialyn stands out as a game-changing support character with a unique mechanic that transforms how teams deal damage. Her special ability converts your team’s Chain Attacks into full Ultimates, letting you use powerful finishing moves more often than any other character allows.
Her kit revolves around a resource called Positive Reviews, which she builds up during combat. When she reaches 90 Positive Reviews, she can upgrade the next teammate’s Chain Attack into an Ultimate. This means your damage dealers can use their strongest attacks multiple times in a single stun window.
Dialyn also provides a 40% damage bonus to all team members through her Overwhelmingly Positive buff. She extends stun durations by 2 seconds and increases the Stun Damage Multiplier by 30%, giving your team more time to deal massive damage.
Best W-Engines for Dialyn
Choosing the right W-Engine greatly improves Dialyn’s performance. Here are the top options:
| W-Engine | Rarity | Why It Works |
| Yesterday Calls (24/7) | S-Rank | Her signature weapon with 24% critical rate. Provides 1.5 energy per second while off-field. Increases team critical damage by 30% when fully stacked. Best option by far. |
| Hellfire Gears | S-Rank | Second best choice with solid energy regeneration at 0.6 per second off-field. Increases Impact when using EX Special Attacks. Great alternative to her signature. |
| Steam Oven | A-Rank | Best budget option with 50% energy regeneration. Helps sustain her frequent EX Special Attack usage. Good for free-to-play players. |
| Precious Fossilized Core | A-Rank | Provides Daze bonuses instead of Impact, which works better with Dialyn’s kit. Lacks energy regeneration but offers strong stun potential. |
Best Drive Discs for Dialyn
Best Choice: King of the Summit (4-piece) + Woodpecker Electro (2-piece)
The 4-piece King of the Summit set increases Daze by 6%. When you use an EX Special Attack or Chain Attack, all team members gain 15% critical damage. If your critical rate is 50% or higher, you get another 15% critical damage for 15 seconds.
The 2-piece Woodpecker Electro provides 8% critical rate. This helps you reach the 100% critical rate goal that converts into Impact through Dialyn’s Core Passive.
Alternative Option: King of the Summit (4-piece) + Swing Jazz (2-piece)
If you already have 100% critical rate from your W-Engine and substats, use Swing Jazz for the 2-piece instead. This gives you 6% energy regeneration, helping you use EX Special Attacks more frequently.
Drive Disc Stats Priority
Here’s what stats you should aim for on each Drive Disc piece:
| Disc Slot | Main Stat | Priority Substats |
| Slot 4 | CRIT Rate | CRIT Rate > CRIT DMG > ATK% |
| Slot 5 | ATK% | CRIT Rate > CRIT DMG > ATK% |
| Slot 6 | Energy Regen | CRIT Rate > CRIT DMG > ATK% |
Substat Priority: CRIT Rate (until 100%) > CRIT DMG > ATK% > PEN
Skill Priority
Level up Dialyn’s skills in this order:
- Core Skill: Top priority for the critical rate conversion and Positive Review mechanics
- Special Attack: Second priority since this is how you build Positive Reviews and Daze
- Chain Attack: Third priority for better Ultimate conversion timing
- Assist: Fourth priority for improved defensive support
- Basic Attack: Lower priority with minor damage contribution
- Dodge: Lowest priority but still provides some utility
How to Play Dialyn
Start combat by using your EX Special Attack combo as early as possible. This applies your 40% damage bonus buff to the whole team. Your EX Special Attacks follow a set pattern: Rock, then Scissors, then Paper. You need 75 total Energy to use all three.
The most important attack is Paper, the final hit in your combo. This applies the Malicious Complaint debuff that extends stun duration and increases the Stun Damage Multiplier. Always make sure to land this attack.
As you fight, build up Positive Reviews by hitting enemies with your EX Special Attacks. Each heavy attack in your combo gives you 7.5 Positive Reviews. You also gain 0.6 Positive Reviews per second while in combat.
When enemies enter stun, your goal is to get multiple Ultimates off. With proper resource management, you can give your team 2-3 Ultimates in a single stun window, massively increasing total damage output.
Final Tips
Remember that Dialyn needs to reach 100% critical rate to maximize her Impact stat through her Core Passive. Every 1% critical rate above 50% gives her 2 Impact, up to 100 bonus Impact at 100% critical rate.
Focus on Energy Regeneration over Impact percentage on your equipment. The faster you can use EX Special Attacks, the faster you can stun enemies and build Positive Reviews.
With the right build and proper resource management, Dialyn becomes an unstoppable support that elevates any team to top-tier performance in Zenless Zone Zero’s hardest content.
