Strengths & Weaknesses

Blade

Strengths
  • “Death Sentence” dumps a huge single-target Wind multiplier into one elite—boss and Apocalyptic Shadow checks are where this Ultimate earns its trace levels.
  • Skill “Hellscape” spends a large HP chunk to refund Energy and advance action—the rotation wants controlled self-damage, not panic healing that cancels the state.
  • Talent “Shuhu's Gift” builds into self-triggered Follow-Up ATKs—stack management is the real rotation, not just Skill spam.
Weaknesses
  • “Shuhu's Gift” Follow-Ups only fire after the Charge/HP conditions are met—wasting Skill or over-healing can strand Blade below the Follow-Up threshold for a full cycle.
  • E0 without “The Unreachable Side” is still clearable, but the gap versus a signature copy is larger than a single eidolon for most Destruction carries—plan the cone before deep eidolon hunting.
  • HP-spend skills mean 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.

Firefly

Strengths
  • Ultimate “Fyrefly Type-IV: Complete Combustion” enters Complete Combustion with full action advance, SPD, and Break-boosted Enhanced attacks—most of the kit’s damage lives inside that window, not on filler Basics.
  • Skill “Order: Aerial Bombardment” spends a large HP chunk to refund Energy and advance action—the rotation wants controlled self-damage, not panic healing that cancels the state.
  • Talent “Chrysalid Pyronexus” scales DMG Reduction with low HP and locks max reduction in the burst state—survivability is written into the damage plan, not bolted on later.
Weaknesses
  • E0 without “Whereabouts Should Dreams Rest” is still clearable, but the gap versus a signature copy is larger than a single eidolon for most Destruction carries—plan the cone before deep eidolon hunting.
  • HP-spend skills mean Firefly 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.
  • Firefly wants Break Effect supports and Toughness bars that can actually be broken; into awkward weakness line-ups the Complete Combustion / Break loop loses most of its damage.

Shared Team Members

With Blade

Gallagher covers HP / memosprite upkeep so the Remembrance loop does not collapse mid-wave.

With Firefly

Gallagher keeps Toughness routes alive with heals (and Break-friendly sustain when built that way).

With Blade

Tingyun is the Advance / DMG amp — time their Skill/Ult for the carry’s damage window.

With Firefly

Tingyun amps Break Effect / action value so Toughness bars die on schedule.

With Blade

Pela applies DEF shred / vulnerability so the carry’s multipliers actually land.

With Firefly

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