King of the Summit for CRIT DMG, 2pc 
Woodpecker Electro to push CRIT Rate past the 50% threshold.
Shockstar Disco adds Impact for faster Stuns.4: CRIT Rate (or ATK) · 5: ATK% · 6: Impact
Prioritize CRIT Rate > Impact > ATK > Energy Regen; aim for 400+ Impact and 60-65% CRIT Rate.
Skill priority: Core Skill > EX Special > remaining skills (optional).
Well worth investing in: a new-generation Stunner who racks up huge Daze while buffing the whole team's CRIT DMG and DMG, flexible enough to slot into both Attack and Rupture cores. Her downsides are that she wants a dual Impact + CRIT build, which burns through good discs, and that you have to order the team correctly to capture all of her native scaling.
Physical Stunner stat priority: aim for 400+ Impact and 60-65% Crit Rate (per game8/gamewith 2.4), stacking Crit DMG after Crit Rate is met. Key threshold: Crit Rate >= 50% to get the full 4pc King of the Summit bonus; beyond that her kit converts EXCESS Crit Rate into Impact (up to +100 Impact per genshinlab), so high Crit Rate raises both damage and Daze. Main stats: Disc 4 Crit Rate (or Crit DMG) / Disc 5 Physical DMG / Disc 6 Impact (or Energy Regen if off-signature). Substat priority: Crit Rate > Crit DMG > ATK% > PEN > Impact. (New agent, numbers from 2.4 guides — medium confidence.)
1) OPENER: enter and use Basic + Special to build Positive Review fast. 2) FIXED EX CHAIN: EX Special: Rock -> (2 Basics) -> EX Special: Scissors -> EX Special: Paper. All three EX cost 75 Energy; after Rock you have ~8s to link Scissors, then ~8s more for Paper; each EX grants 7.5 PR (full combo = +22.5 PR). 3) Paper applies Malicious Complaint — a debuff that raises damage taken, EXTENDS Stun, and adds +15% Stun DMG Multiplier (once the target is Stunned): this is the burst window. 4) At 90 Positive Review (or after an Ultimate) you gain Customer Complaint: HOLD Basic to fire Get Lost! and force a Chain Attack. 5) That Chain lets the NEXT ally cast their Ultimate immediately without spending Decibel -> swap to your main DPS to unload during the Stun, then repeat from step 2.
Positive Review gain +16%; while Overwhelmingly Positive is active the whole team IGNORES 15% enemy RES (per genshinlab). For a stunner-buffer, team-wide 15% RES ignore is a very practical damage bump and speeds up Customer Complaint / Chain uptime — the first meaningful stopping point for most players.
Enemies afflicted by Malicious Complaint take +20% Stun DMG and all units deal +15% damage to them (per genshinlab). It stacks directly into the burst window Dialyn already opens — the biggest team jump among the cheap mindscapes; many guides treat M1-M2 as the combo that completes her enabler role. Note: new agent, the 20%/15% figures are from genshinlab and unconfirmed against game8/prydwen (medium confidence).
All skills (Basic / Dodge / Assist / Special / Chain) +2 levels. A flat numeric bump with no gameplay change — low value, a stepping stone to M4.
Recover 20 Energy on combat entry and +500 ATK while Overwhelmingly Positive (per genshinlab). Mostly an energy-QoL that lets the EX combo start sooner off-signature; +500 ATK is modest for a stunner. Moderate value, not worth pulling for on its own.
All skills +2 levels again. Still just flat numbers, a bridge to M6 — low value.
The biggest damage jump: when an ally enters with an Ultimate via Dialyn's Core, that ally gains Aftertone — each of their hits makes Dialyn deal an extra instance of Physical DMG equal to 480% of Dialyn's ATK (per genshinlab). Turns her from a pure enabler into a meaningful secondary damage source, but it's whale-tier — most players stop at M1/M2.
- Top-tier enabler: forces a Chain and gives the next ally a FREE (no-Decibel) Ultimate — massively raising the main DPS's burst frequency.
- Strong stunner: Malicious Complaint extends Stun and adds +15% Stun DMG Multiplier, opening a long, heavy burst window for the whole team.
- Buffs and deals damage: excess Crit is converted into Impact (kit) and at M6 she adds a big Physical DMG instance — not an 'inert' Daze-only stunner.
- Flexible teams: covers the Stun slot for both Attack DPS (Evelyn, Ye Shunguang) and Rupture DPS (Yixuan, Banyue) thanks to a universal buff/enable frame.
- The Rock->Scissors->Paper EX chain is timing-gated (~8s per step) and costs 75 Energy — dropping a step loses Malicious Complaint, demanding disciplined execution and energy management.
- Dual stat-hungry: needs 400+ Impact AND 60-65% Crit Rate to optimize both Daze and damage — heavier disc farming than a pure-Impact stunner.
- Reliant on her signature Yesterday Calls (Crit Rate + off-field energy + team Crit DMG buff); off-signature you must give up the Energy Regen main stat on Disc 6.
Excellent in Shiyu Defense: an ideal single-target enabler — Stun extension + free Ultimates for the main DPS (Evelyn/Ye Shunguang or Yixuan) pile burst onto the boss in the Stun window and clear a side fast. (Inferred from kit + 2.4 sample teams, medium confidence.)
Also strong in Deadly Assault: against high-HP foes the free-Ultimate chain + Stun extension + RES pen (M1) lets the main DPS post high scores; rotates well with Rupture (Yixuan + Lucia) or Attack (Evelyn + Astra Yao). (Inferred from kit + guide teams, medium confidence.)

Upon entering the battlefield, Dialyn starts with 60 Positive Reviews. If her initial CRIT Rate surpasses 50%, her Impact increases by 1.4% for each additional 1%, up to a maximum increase of 100. After using EX Special Attack: Rock, the next EX Special Attack becomes EX Special Attack: Scissors for 8s. After using EX Special Attack: Scissors, the next EX Special Attack becomes EX Special Attack: Paper! for 8s. When EX Special Attack: Paper! hits an enemy, it applies the Malicious Complaint effect. While under Malicious Complaint, if the enemy becomes Stunned, the Stun duration is extended by 2s, and Stun DMG Multiplier increases by 15%. Before recovering from Stun, Malicious Complaint can trigger on the same target only once. The Stun duration bonus does not stack with similar effects. When an enemy with Malicious Complaint recovers from being Stunned, the effect ends. While in combat, Dialyn gains 0.6 Positive Reviews per second. When a heavy attack of EX Special Attack: Rock, EX Special Attack: Scissors, or EX Special Attack: Paper! hits enemies, she gains 7.5 Positive Reviews. Each use of a skill can grant this bonus only once, up to a maximum of 120. With at least 90 Positive Reviews, when Dialyn triggers the Chain Attack window using Chain Attack: Welcome Mat, EX Special Attack: Get Lost!, or Quick Assist: Forward Call, the next character to switch in will have their Chain Attack upgraded to an Ultimate. When an ally launches an Ultimate this way, Dialyn consumes 60 Positive Reviews.

A maximum of 1 Customer Complaint can be held at a time.*Stats shown are at Base level.
Additional Ability: External Line
When another character in your squad is an Attack or Rupture character: Dialyn's EX Special Attack CRIT DMG is increased by 50%. When an EX Special Attack or Ultimate is activated, all squad members gain the Overwhelmingly Positive effect. While Overwhelmingly Positive is active, DMG dealt is increased by 40% for 15s. When Dialyn uses an EX Special Attack or Ultimate while Overwhelmingly Positive is active, if the remaining duration of Overwhelmingly Positive is less than 35s, its duration is extended by 10s. When a heavy attack from EX Special Attack: Rock, EX Special Attack: Scissors, or EX Special Attack: Paper! hits, additional DMG is dealt based on the previous squad member's Specialty: If the squad member is an Attack Agent, EX Special Attack: Rock, EX Special Attack: Scissors, and EX Special Attack: Paper! deal additional DMG equal to 320% of that Attack Agent's ATK. If the squad member is a Rupture Agent, EX Special Attack: Rock, EX Special Attack: Scissors, and EX Special Attack: Paper! deal additional DMG equal to 400% of that Rupture Agent's Sheer Force.
