Strengths & Weaknesses

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.

Gilgamesh

Strengths
  • Ultimate “Enuma Elish” hits every enemy on the field in one cast—level this before polishing filler traces.
  • “Gate of Babylon” Blast-hits the main target plus adjacent enemies, so adjacent elites still take meaningful chip without waiting for Ultimate.
  • Talent “"Amuse Me to the Fullest"” When a teammate uses their Ultimate—damage keeps flowing even when Gilgamesh is not the active turn.
Weaknesses
  • Follow-Ups from “"Amuse Me to the Fullest"” need allies who actually Basic ATK on schedule—freeze/CC on the team stalls Gilgamesh’s off-turn damage.
  • E0 without “I Am As You Behold” 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.
  • Spamming “Gate of Babylon” every turn without watching Skill Points strands the rest of the team—Gilgamesh is often the SP sink.

Shared Team Members

With Firefly

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

With Gilgamesh

Tingyun is the Advance / Energy amp — keep her Skill on Gilgamesh for Ult uptime.

With Firefly

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

With Gilgamesh

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

With Firefly

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

With Gilgamesh

Gallagher covers healing so the carry can stay on-curve without a limited Abundance.
