Acheron vs The Dahlia

• Burst kit built around one Ultimate: Rainblades into Stygian Resurge clear packs while ignoring Toughness type and applying all-type RES shred for the whole sequence—so she stays viable even when Lightning is not on the weakness list.
• Trace A4’s 1.6× personal damage multiplier (with two other Nihility allies) sits outside normal DMG% stacking, so her ceiling does not depend on borrowing Robin, Ruan Mei, or Sparkle from the other Memory of Chaos side.
• Debuff teammates double as fuel—every ally application feeds Slashed Dream and Crimson Knot—so well-built Nihility cores keep Ultimates cycling in MoC and Pure Fiction without Energy-battery supports.

• Full A4 scaling wants three Nihility characters on the roster (E2 lowers that to two paths total); swapping in Harmony for the second Nihility slot only works with well-built supports and still forgoes part of her multiplier.
• Most of her damage is booked into one Ultimate—Rainblades that remove too few Crimson Knot stacks, or hit the wrong enemy in multi-target fights, can waste the bulk of the rotation.
• Basic ATK and Skill ratios are modest compared with many newer 3.x carries; she climbs tiers through debuff-fed stacking, type-agnostic break, and RES shred during Ult—not steady single-target Skill spam.

• 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.
