At a Glance
Strengths & Weaknesses
Mortenax Blade
- Ultimate “Fornax Ex Corpore” spends HP as a deliberate self-damage cost—level this before polishing filler traces.
- Skill “A Rain of Blades Seals Fate” spends HP as a deliberate self-damage cost—the rotation wants controlled self-damage, not panic healing that cancels the state.
- Talent “All Karma Comes Due” fires Follow-Up ATKs off ally Basics—damage keeps flowing even when Mortenax Blade is not the active turn.
- Follow-Ups from “All Karma Comes Due” need allies who actually Basic ATK on schedule—freeze/CC on the team stalls Mortenax Blade’s off-turn damage.
- HP-spend skills mean Mortenax Blade can soft-lock if sustain is weak or if a healer tops them up at the wrong time and breaks a low-HP / Charge condition.
- Spamming “A Rain of Blades Seals Fate” every turn without watching Skill Points strands the rest of the team—Mortenax Blade is often the SP sink.
The Dahlia
- 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.
- “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.
