Guinaifen | Honkai: Star Rail

Overview

Fire Nihility support who applies Burn and stacks Firekiss vulnerability when enemies take Burn damage.

Role

Burn applier and damage-taken debuffer.

Playstyle

Skill to spread Burn, let ticks build Firekiss, and Ultimate to trigger Burns early before allied damage windows.

Why It Works

Burn ticks build Firekiss, increasing all damage enemies receive and giving her value beyond personal DoT.

Watch For

Short fights may end before Firekiss stacks, and low Effect Hit Rate makes both Burn application and team amplification unreliable.

Playstyle

Combat Flow

Use Skill to Burn a target and its neighbors. Trigger existing Burns with Ultimate before the team's important attacks to help build Firekiss. Use Basic to conserve Skill Points when High Poles can maintain the needed Burn.

Key Notes

Firekiss increases all damage received, not only DoT damage.
Basic's Burn has an 80% base chance, lower than Skill's application chance.
Bladed Hoop advances Guinaifen's opening action, helping establish debuffs early.
Do not assume Firekiss starts at full stacks without Burn damage or Technique applications.
Ultimate triggers Burn specifically, not every kind of DoT.

Build & Investment

Light Cones

Primary

Eyes of the Prey

Adds Effect Hit Rate and DoT damage for a Burn damage role.

Alternative

Resolution Shines As Pearls of Sweat

For team support: a hit can apply one-turn Ensnared and reduce DEF when Ensnared is not already active.

Relics

Primary

Prisoner in Deep Confinement

For personal DoT damage: adds ATK and ignores DEF according to up to three DoTs on the target.

Situational

Messenger Traversing Hackerspace

Use the two-piece SPD bonus with another useful two-piece set for a support build. Guinaifen's enemy-targeting Ultimate cannot trigger Messenger's four-piece effect.

Planars

Primary

Fleet of the Ageless

For team support: grants HP and team ATK at 120 SPD.

Alternative

Firmament Frontline: Glamoth

For personal damage: grants ATK and damage bonuses at 135 or 160 SPD.

Eidolon Investment

E0 supplies Burn and Firekiss. E1 adds another debuff and supports application reliability; E4 helps Energy, and E6 raises the Firekiss ceiling.

Eyes of the Prey supports Burn damage and reliability, while Resolution supports team damage through DEF reduction.

Skill has a 100% base chance to reduce the attacked enemies' Effect RES by 10% for two turns.

When an enemy is Burned, the multiplier of Guinaifen's Basic- or Skill-applied Burn increases by 40 percentage points.

Each time Guinaifen's own Burn deals damage, she restores 2 Energy.

Raises the maximum number of Firekiss stacks by one.

Teams

Recommended Teammates

Kafka

Kafka's Skill triggers Guinaifen's Burn, helping build Firekiss and, at Guinaifen E4, generate Energy. Keep enough Skill Points for Kafka's attacks.

Acheron

Guinaifen contributes a Nihility slot, Burn and Firekiss for Acheron. Apply debuffs consistently and respect Acheron's one-stack-per-ability limit rather than counting every Burn tick as a new stack.
