Dialyn
Who is Dialyn?
Dialyn is a limited S-rank Physical Stun agent from the Krampus Compliance Authority faction in Zenless Zone Zero. A meta-defining Stunner, she features an Ultimate conversion mechanic that transforms ally Chain Attacks into Ultimates without consuming Decibels, enabling entirely new high-damage combo routes. She also extends Stun duration on enemies and provides CRIT DMG buffs to teammates. Her value is exceptionally high on Rupture teams — she works alongside Banyue, Yidhari, and other Rupture DPS as their premier Stun enabler.
Kit Summary
Dialyn cycles her EX Special through Rock-Scissors-Paper sequences to accumulate Positive Reviews. At 90+ stacks she triggers a Chain Attack window that converts ally Chain Attacks into Ultimates.
The signature mechanic — allows teammates to use their Ultimates via Chain Attack without spending Decibels, enabling extended Stun windows and damage combos unavailable with other Stunners.
A passive debuff that extends Stun duration on targets and applies a damage multiplier bonus, amplifying Stun-window burst for the full team.
Core Passive provides CRIT DMG bonus to the team when Dialyn has 100% CRIT Rate built, rewarding precise stat investment.
Her Stun duration extension and damage multipliers synergise heavily with Rupture agents who output the most damage during Stun windows.

F2P Verdict
Dialyn is a limited S-rank — requires pulling on her banner. She is worth prioritising over most other limited Stunners given her meta-wide applicability.
Her signature W-Engine is strongly recommended for the CRIT DMG buff; Hellfire Gears is the best accessible fallback.
Frequently Asked Questions
How does the Ultimate conversion mechanic work?
When Dialyn's Positive Reviews gauge reaches 90+, she triggers a special Chain Attack window. During this window, any ally who uses a Chain Attack instead fires their Ultimate — without consuming Decibels. This is extremely powerful because it allows back-to-back Ultimates from multiple agents during a single Stun window, a combo impossible with other Stunners.
Why does Dialyn need 100% CRIT Rate?
Her Core Skill provides a CRIT DMG bonus to the team only when Dialyn herself has 100% CRIT Rate. Meeting this threshold is not required for her basic function but unlocks a meaningful team-wide CRIT DMG buff that significantly boosts DPS output.
Is Dialyn useful outside Rupture teams?
Yes — Dialyn's Ultimate conversion and Stun duration extension provide value on any team that benefits from extended Stun windows and free Ultimates. She works with Ye Shunguang, Starlight Billy, and standard Attack DPS beyond the Rupture niche.
