Guinaifen
Situational—Guinaifen applies Burn + Firekiss vulnerability. Ultimate “Watch This Showstopper” hits every enemy on the field in one cast. Best with Kafka / Acheron / Himeko. EHR + ATK investment heavy for a 4★ support. Skip when better Nihility debuffers already staffed.
Guinaifen is a 4★ Fire Nihility DoT DPS. Skill “Blazing Welcome” is the primary in-combat spend. Ultimate “Watch This Showstopper” is the payoff window for damage or team utility. This Phase 1 page covers kit text, gear targets, and pull notes—team comps stay empty until Phase 2.

Strengths
- Ultimate “Watch This Showstopper” hits the full field and forces DoT application/detonation in one cast—Pure Fiction waves melt once the status is seeded.
- “Blazing Welcome” Blast-hits the main target plus adjacent enemies, so adjacent elites still take meaningful chip without waiting for Ultimate.
- Talent “PatrAeon Benefits” rolls a base-chance debuff that wants Effect Hit Rate—miss the stack conditions and the burst window feels empty.
- Technique “Skill Showcase” opens by hitting the pack on pull-in—use it before every MoC wave, not only in the overworld.
Weaknesses
- Several Guinaifen effects roll “base chance”—without enough Effect Hit Rate, Exposed/Shock/DEF shred simply misses on tanky bosses and the rotation feels empty.
- DoT damage needs other appliers or long-lived statuses on the field—Guinaifen alone cannot keep every wave fully stacked without a second DoT partner.
- As a 4★ Nihility unit, Guinaifen is easy to gear for early/mid game but usually loses the niche race to a modern limited option once that banner is built.
- Spamming “Blazing Welcome” every turn without watching Skill Points strands the rest of the team—Guinaifen is often the SP sink.
Trace Priority
Blazing Welcome carries most of the kit’s damage or utility—level this first.
Watch This Showstopper supports the main rotation—raise after the top priority traces.
PatrAeon Benefits supports the main rotation—raise after the top priority traces.
Standing Ovation is last priority outside of filling trace materials.
Stat Priority
Open with Technique if it helps, spend Skill to advance the kit’s resource, and hold Ultimate for the damage or buff window. Exact teammate order lands in Phase 2.
Open supports first, then spend the carry’s Skill/Ult inside the buff window. Exact order varies by the team tab above.
Light Cones
5★ · Path cone
Increases the wearer's Effect Hit Rate by 0.24%. When the wearer deals DMG to an enemy that currently has 3 or more debuffs, increases the wearer's CRIT Rate by 0.12%. After the wearer uses their Basic ATK, Skill, or Ultimate, there is a 1% base chance to implant Aether Code on a random hit target that does not yet have it. Targets with Aether Code receive 0.12% increased DMG for 1 turn.
Why it works —Strong Nihility option for Guinaifen; use while farming or if signature is unavailable.
5★ · Path cone
Increases DMG dealt by the wearer by 0.24%. After every attack launched by wearer, their SPD increases by #3[f1]%, stacking up to 3 times. If the wearer hits an enemy target that is not afflicted by Erode, there is a 100% base chance to inflict Erode to the target. Enemies afflicted with Erode are also considered to be Shocked and will receive Lightning DoT at the start of each turn equal to 0.6% of the wearer's ATK, lasting for 1 turn(s).
Why it works —Flexible alternative on the same path—equip if you already own it at higher superimposition.
4★ · Path cone
For every debuff the target enemy has, the DMG dealt by the wearer increases by 0.12%, stacking up to 3 time(s). This effect also applies to DoT.
Why it works —Best accessible option for most accounts—raise superimposition when copies drop.
4★ · Path cone
Increase the wearer's CRIT Rate by 0.08%. The wearer deals 0.24% more CRIT DMG to enemies that are currently Slowed or have reduced DEF.
Why it works —Budget path cone—fine while building the account.
Relics
Team Compositions
Primary DoT detonation team for Guinaifen. Kafka, Acheron, Huohuo are the partners the kit / endgame clears assume first.
Core carry for this shell — owns the damage plan and sets the rotation pace.
Kafka seeds or detonates DoTs — without a second DoT piece the detonation loop stalls.
Acheron seeds or detonates DoTs — without a second DoT piece the detonation loop stalls.
Huohuo covers healing (and often Energy / cleanse) so the carry can stay on-curve.
Traces & Eidolons
Traces
Deals Fire DMG equal to 140% of Guinaifen's ATK to one designated enemy.
Deals Fire DMG equal to 150% of Guinaifen's ATK to one designated enemy and Fire DMG equal to 50% of Guinaifen's ATK to any adjacent enemies, with a 100% base chance to Burn the target and adjacent targets.

Deals Fire DMG equal to 144.0% of Guinaifen's ATK to all enemies. If the target enemy is currently inflicted with Burn, then their Burn status immediately produces DMG equal to 102% of their original DMG.
When Guinaifen is on the field, there is a 100% base chance to apply Firekiss to an enemy after their Burn status causes DMG. While inflicted with Firekiss, the enemy receives 8.5% increased DMG, which lasts for 3 turn(s) and can stack up to 3 time(s).

Is it worth getting?
Small 4★ bump: Pads Effect RES during the enhanced state. Take dupes when they appear on rate-up; never the reason you pull the banner.
When an enemy target is being Burned, the DMG multiplier of the Burn status applied by her Basic ATK or Skill increases by 40%.
Is it worth getting?
Kit add-on: When an enemy target is being Burned. Evaluate against your supports—pull only if that specific clause solves a problem you actually hit.
Skill Lv. +2, up to a maximum of Lv. 15. Basic ATK Lv. +1, up to a maximum of Lv. 10.
Is it worth getting?
Skill + Basic ATK levels only (+2). Free if you roll into it; never spend currency aiming for E3.
Every time the Burn status inflicted by Guinaifen causes DMG, Guinaifen regenerates 2 Energy.
Is it worth getting?
Side-grade: Refunds Energy when the listed trigger fires. Happy if it drops; not a planned stopping point.
Ultimate Lv. +2, up to a maximum of Lv. 15. Talent Lv. +2, up to a maximum of Lv. 15.
Is it worth getting?
Ultimate + Talent levels only (+2). Skip as a goal—grab it if you overshoot toward E6, never hard-pity for it.

Is it worth getting?
Whale ceiling: Increases the stackable Firekiss count by 1. Only chase if Guinaifen is your dedicated Nihility main and E0–E2 already feel finished.
