At a Glance
Strengths & Weaknesses
Firefly
- 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.
- 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.
Phainon
- Ultimate “He Who Bears the World Must Burn” hits every enemy on the field in one cast—most of the kit’s damage lives inside that window, not on filler Basics.
- “Let There Be Light” Blast-hits the main target plus adjacent enemies, so adjacent elites still take meaningful chip without waiting for Ultimate.
- Talent “Pyric Corpus” buffs allies’ damage for a short window—ignore it and Phainon plays like a worse generic Destruction unit.
- E0 without “Thus Burns the Dawn” 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 “He Who Bears the World Must Burn”, Phainon spends turns on Basics and the kit’s advertised multipliers never show up on the combat log.
- Spamming “Let There Be Light” every turn without watching Skill Points strands the rest of the team—Phainon is often the SP sink.
Shared Team Members
With Firefly
Tingyun amps Break Effect / action value so Toughness bars die on schedule.
With Phainon
Tingyun is the Advance / DMG amp — time their Skill/Ult for the carry’s damage window.
With Firefly
Pela enables Super Break / Toughness pressure rather than a generic CRIT Harmony slot.
With Phainon
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 Phainon
Gallagher covers healing (and often Energy / cleanse) so the carry can stay on-curve.
