Strengths & Weaknesses

Cartethyia

Strengths
  • Liberation “A Knight's Heartfelt Prayers” routes damage through mid-air / plunging attack chains — that window is where Cartethyia’s clear speed actually shows up.
  • Forte “Tempest” routes damage through mid-air / plunging attack chains, so resource banking is mandatory, not optional filler.
  • Outro “Wind's Divine Blessing” amplifies the incoming Resonator’s damage on Outro handoff — swap timing is part of the damage plan, not just Concerto filling.
Weaknesses
  • Field-time hungry once Liberation “A Knight's Heartfelt Prayers” is up — double-DPS swaps dilute the dump window.
  • Wants dedicated supports and ER planning; dropped into a random squad, Liberation uptime falls off a cliff.

Iuno

Strengths
  • Liberation “Beneath Lunar Tides” routes damage through mid-air / plunging attack chains — that window is where Iuno’s clear speed actually shows up.
  • Forte “Ebb and Flow” restores HP across threatened allies while banking Concerto, so resource banking is mandatory, not optional filler.
  • Outro “From Gloom to Gleam” hands the next Resonator a Heavy/Basic Attack Amplification window — swap timing is part of the damage plan, not just Concerto filling.
Weaknesses
  • Field-time hungry once Liberation “Beneath Lunar Tides” is up — double-DPS swaps dilute the dump window.
  • Wants dedicated supports and ER planning; dropped into a random squad, Liberation uptime falls off a cliff.

With Cartethyia

But most importantly, Ciaccona applies a ton of Aero Erosion off-field over time, which allows Cartethyia to make full leverage of her kit buffs.

With Iuno

while Ciaccona has no Outro buff dedicated to Iuno, she does provide solid personal damage, a super fast rotation and a lot of Aero DMG increases in the form of DMG Bonus and RES Shred with her Signature.
