Strengths & Weaknesses

Black Swan

Strengths
  • Ultimate “Bliss of Otherworld's Embrace” hits the full field and forces DoT application/detonation in one cast—Pure Fiction waves melt once the status is seeded.
  • “Decadence, False Twilight” Blast-hits the main target plus adjacent enemies, so adjacent elites still take meaningful chip without waiting for Ultimate.
  • Talent “Loom of Fate's Caprice” Blast-hits the main target plus adjacent enemies—miss the stack conditions and the burst window feels empty.
Weaknesses
  • Several Black Swan effects roll “base chance”—without enough Effect Hit Rate, Exposed/Shock/DEF shred simply misses on tanky bosses and the rotation feels empty.
  • E0 without “Reforged Remembrance” is still clearable, but the gap versus a signature copy is larger than a single eidolon for most Nihility carries—plan the cone before deep eidolon hunting.
  • DoT damage needs other appliers or long-lived statuses on the field—Black Swan alone cannot keep every wave fully stacked without a second DoT partner.

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.
