Strengths & Weaknesses

Luka

Strengths
  • “Coup de Grâce” dumps a huge single-target Physical multiplier into one elite—boss and Apocalyptic Shadow checks are where this Ultimate earns its trace levels.
  • Skill “Lacerating Fist” rolls a base-chance debuff that wants Effect Hit Rate—that is how Luka applies pressure between Ultimates.
  • Talent “Flying Sparks” seeds or detonates DoT statuses in the same cast—miss the stack conditions and the burst window feels empty.
Weaknesses
  • Several Luka 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—Luka alone cannot keep every wave fully stacked without a second DoT partner.
  • As a 4★ Nihility unit, Luka is easy to gear for early/mid game but usually loses the niche race to a modern limited option once that banner is built.

The Dahlia

Strengths
  • Ultimate “Wallow... Entombed Ash” hits every enemy on the field in one cast—level this before polishing filler traces.
  • “Lick... Enkindled Betrayal” Blast-hits the main target plus adjacent enemies, so adjacent elites still take meaningful chip without waiting for Ultimate.
  • Talent “Who's Afraid of Constance?” fires Follow-Up ATKs off ally Basics—stack management is the real rotation, not just Skill spam.
Weaknesses
  • “Who's Afraid of Constance?” Follow-Ups only fire after the Charge/HP conditions are met—wasting Skill or over-healing can strand The Dahlia below the Follow-Up threshold for a full cycle.
  • If Energy or Skill Points starve “Wallow... Entombed Ash”, The Dahlia spends turns on Basics and the kit’s advertised multipliers never show up on the combat log.
  • Spamming “Lick... Enkindled Betrayal” every turn without watching Skill Points strands the rest of the team—The Dahlia is often the SP sink.

Shared Team Members

With Luka

Fugue seeds or detonates DoTs — without a second DoT piece the detonation loop stalls.

With The Dahlia

Fugue enables Super Break / Toughness pressure rather than a generic CRIT Harmony slot.

With Luka

Boothill is the damage seat in this shell — build the supports around their rotation, not the reverse.
