Acheron vs Fugue

• 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 “Solar Splendor Shines Upon All” hits every enemy on the field in one cast—time it for the carry’s damage window instead of casting on cooldown out of habit.
• Skill “Virtue Beckons Bliss” applies DEF shred / Exposed for the team—that is how Fugue applies pressure between Ultimates.
• Fugue can implant or force Fire-relevant Weakness from the kit itself—Break and Toughness routes stay online even when the MoC line-up did not list Fire.

• Several Fugue effects roll “base chance”—without enough Effect Hit Rate, Exposed/Shock/DEF shred simply misses on tanky bosses and the rotation feels empty.
• Buff windows on “Solar Splendor Shines Upon All” are short—casting them when the carry cannot attack wastes the CRIT DMG/ATK amp for a full cycle.
• Fugue’s Skill is often the expensive part of the rotation; SP-negative teams force Basic ATKs and you lose the advance/amp that made the unit worth playing.
