At a Glance
Strengths & Weaknesses
Arlan
- “Frenzied Punishment” dumps a huge single-target Lightning multiplier into one elite—boss and Apocalyptic Shadow checks are where this Ultimate earns its trace levels.
- Skill “Shackle Breaker” spends HP as a deliberate self-damage cost—this is the spend that keeps the rotation honest.
- Talent “Pain and Anger” Based on Arlan's current missing HP percentage—miss the stack conditions and the burst window feels empty.
- HP-spend skills mean Arlan 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.
- As a 4★ Destruction unit, Arlan is easy to gear for early/mid game but usually loses the niche race to a modern limited option once that banner is built.
- Spamming “Shackle Breaker” every turn without watching Skill Points strands the rest of the team—Arlan is often the SP sink.
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.
