Overview
Denia is a 5★ Fusion Rectifier Sub-DPS from Ren Realm. She fields a short cycle, applies Tune Strain and her damage amp, then outros into Qingxiao. If you skip her, Qingxiao still functions with a weaker Aero support — the ceiling drops, the page does not disappear.
Rotation
Healer outros. Denia intros, Resonance Skill, Forte Circuit, Resonance Liberation if it is part of the amp package, outro into Qingxiao. Qingxiao spends the window. Do not leash the field like Encore.
Strengths
Locks Qingxiao's premium core. Phase 1 rerun timing matches the live banner. Sequence 0 is enough.
Weaknesses
Useless in a vacuum if you never field a Tune Strain carry. Forged Dwarf Star is a second Convene. Not Jingran.
Investment
Skill and Liberation first. Waveplates wait until Qingxiao is pulled or planned. Fusion Accretion or Cosmic Ripples hold the weapon slot.
Common Mistakes
Main-DPS Molten Rift with no Qingxiao. Pulling the weapon Convene for a flex slot. Cloning her onto a Changli side that already has Lupa and Mortefi.
