Overview

Strengths

  • Everlasting Ember at T5 raises a 300% HP team shield and 10% Ignore Damage Reduction for allies whenever she uses Ultimate or Active.
  • Authority of Flame is +70% Melee Attack and +5% Attack Amp for the party, plus an extra basic-attack target on herself.
  • Scorching Judgment hits 2068% Attack and adds 376% when Burn is present, while Blazing Wheel Slash stacks up to +100% Ultimate/Passive skill damage.

Weaknesses

  • Burn enable is tied to the Everlasting Ember buff window. Drop the rotation and the ultimate loses its follow-up.
  • Brawl only reaches B; short skirmishes underuse the shield refresh and the five-stack skill-damage climb.
  • Passive priority over Ultimate means underleveled Ember and Authority leave her as a soft Knight with a big button.

Investment

Extra copies

Prioritize the character card before Transcend. The card supports her hybrid role; climb Transcend to T5 once the card investment is in place.

Transcend stop

Stop at T5. That is where the team shield hits 300% HP, melee Attack reaches 70%, and Blazing Wheel Slash's skill-damage stack is fully valued.

Review

Swordbringer Updated Sep 5, 2026

Flame Kay is a Holy Knight in the front line who refuses to pick one job. The tier list has her at S+ for DPS, Support, and Tank in both PVE and Raids because the same passives that keep the party alive also feed her Burn and her ultimate. Skill priority puts Passive 1 = Passive 2 above Active and Ultimate for a reason.

Everlasting Ember is the spine. Using Ultimate or Active grants a team shield equal to 300% of her HP at T5 and gives all allies 10% Ignore Damage Reduction for 5s. While the Ember buff is active, her basic attacks apply Burn: 120% Attack every 1s for 3s, stacking. That Burn is the enable for the ultimate's bonus hit, so the shield rotation is also the damage rotation.

Authority of Flame at T5 gives allies +70% Melee Attack and +5% Attack Amp, gives her +15% Critical Hit Chance, and adds +1 target to her basic attacks. Melee comps (Karishara and Dian Cecht are the listed partners) treat this as a party weapon. The extra basic target also spreads Burn faster while Ember is up.

Blazing Wheel Slash hits forward enemies for 525% Attack on an 8s cooldown and stacks a permanent +20% Ultimate and Passive skill-damage buff per cast, max 5 stacks (+100%). Build stacks before you expect the ultimate to look like an S+ nuke.

Scorching Judgment at T5 hits all enemies for 2068% Attack. If any enemy is Burning, it adds a 376% Attack hit and stacks Critical Resistance reduction (2% per stack). No Burn, no follow-up, which loops back to keeping Ember active.

PVP sits at A across roles; Brawl at B. The kit wants time to refresh the shield and bank Wheel stacks. Named gear is Fragarach (Attack %, Crit DMG %), Warrior Armor (Block %), Glory of the Empire (HP %), and Rune of Focus (Crit DMG %). HP% on the accessory directly inflates the 300% team shield; block keeps her alive to press Active again.

Build her as the frontline engine: shield, melee aura, Burn, then ultimate. She is not a pure tank who forgot to deal damage, and she is not a carry who forgot to protect the party. The T5 numbers do both on the same buttons.
