Front Chaos Knight who only pays off when Fear is already on the board. Without that setup she is a mid B-tier cleaver with a short Defense shred.

Overview

Strengths

  • War Cry locks in +88% Critical Damage at Transcend 5, so every crit line on Fragarach and Rune of Focus actually lands.
  • Eruption adds a stackable Defense -9% (max 2) for 10s on a 7s cooldown while still hitting the full wave for 450% Attack.
  • Devour and Eruption both bank Fear bonus damage, 150% and 90% extra respectively, when Circe or another Fear source is online.

Weaknesses

  • Kit never applies Fear itself; Circe or an equivalent partner is mandatory or the bonus lines are dead text.
  • PVP sits at D: 34s ultimate cadence and no self-Fear leave her too slow for arena tempos.
  • Passive 2 is pure survivability (HP +88%, Crit Rate +9%); it does not fix the setup dependency.

Investment

Extra copies

Put extras into Transcend before hunting a character card. Skill levels on War Cry and Eruption matter more than a second copy sitting idle.

Transcend stop

Stop at T0. Further Transcend ranks are optional luxury once the Fear partner and Fragarach lines are already built.

Review

Lucy is a Chaos Knight on the front line whose kit is written around Fear, not around tanking. She does not apply Fear herself. Every meaningful damage rider on her skills assumes someone else already put that status on the wave.

War Cry is the priority passive for a reason. At Transcend 5 it is a permanent +88% Critical Damage on herself. That is why the named loadout leans into crit damage: Fragarach (Attack% + Crit DMG%), Rune of Focus (HP% + Crit DMG%), with Merlin's Robe and Glory of the Empire covering block, crit resistance, and HP%. Crit rate is thin in her own kit: Passive 2 only adds +9%, so a buffer or weapon line that feeds rate still matters.

Eruption is the workhorse. Full-wave hit for 450% Attack on a 7s cooldown, 90% additional damage into Fear targets, and a Defense shred of -9% per stack (max 2) for 10 seconds. Two stacks stick for most of a short fight if you keep casting. Skill priority puts Passive 1 above Ultimate = Active, then Passive 2 last: get the crit damage online, then level the buttons that actually hit.

Devour is the big button: 980% Attack to all enemies, 150% additional into Fear, 34s cooldown. It is a spike, not a rotation. In PVE and Raids she sits at B DPS; Brawl matches that. PVP drops to D because a half-minute ultimate and a Fear tax do not survive arena clocks.

Eclipse (Passive 2) is +88% HP and that small crit-rate bump. It keeps a frontliner alive; it does not invent damage. Synergy names on this site are Circe and Dian Cecht: Fear application and sustain so the bonus lines and the shred actually matter.

Build her only if you already run a Fear team. Without that partner she is a generic AoE Knight with a short Defense down and a long ultimate. With Fear online, War Cry plus double-stack Eruption shred turns the same buttons into real clear speed. Transcend first, park at T0, and spend the rest of the account on the unit that applies Fear rather than chasing Lucy past the floor.
