Strengths & Weaknesses

Clara

Strengths
  • Ultimate “Promise, Not Command” Blast-hits the main target plus adjacent enemies—level this before polishing filler traces.
  • Skill “Svarog Watches Over You” hits every enemy on the field in one cast—this is the spend that keeps the rotation honest.
  • Talent “Because We're Family” Under the protection of Svarog, DMG taken by Clara when hit by enemy attacks is reduced by 10%—ignore it and Clara plays like a worse generic Destruction unit.
Weaknesses
  • E0 without “Something Irreplaceable” 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.
  • If Energy or Skill Points starve “Promise, Not Command”, Clara spends turns on Basics and the kit’s advertised multipliers never show up on the combat log.
  • Spamming “Svarog Watches Over You” every turn without watching Skill Points strands the rest of the team—Clara is often the SP sink.

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 Clara

Gallagher covers healing (and often Energy / cleanse) so the carry can stay on-curve.

With Firefly

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

With Clara

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 Clara

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.
