Detailed guide

In short: Diona is a versatile 4★ support: she shields, heals and applies Cryo. Her shield and healing scale with HP, so she's easy to build: HP% main stats, Energy Recharge in the substats, and almost any artifacts will do.

How she plays: her Skill, Icy Paws, deals Cryo damage and creates a shield that absorbs Cryo damage with 250% effectiveness. Holding it fires five paws instead of two and gives a 75% stronger shield; the more paws hit, the longer the shield lasts. Her Burst, Signature Mix, creates a Drunken Mist field that deals Cryo damage and heals characters inside it. Her passive lowers the ATK of enemies in the mist by 10%.

Stats: HP — the more the better, aim for 20–25k. Energy Recharge 150–180%: her Burst costs 80 energy. Crit Rate only matters with the Favonius Warbow.

Partners: the classic is Freeze with Ayaka or Ganyu, where Diona fills the healer slot and provides Cryo Resonance. In 7.x she fits Sandrone's Stellar-Conduct teams in place of Qiqi: a Cryo healer with a shield. In Superconduct with Eula her shield protects against interruptions.

Constellations: C1 restores 15 energy after her Burst — a good stopping point for light investment. C2 shares the shield with nearby allies. C6 gives characters in the mist +200 Elemental Mastery above 50% HP and +30% incoming healing below 50% HP — a strong buff for reaction teams.

Weaknesses: her Burst field doesn't move, which is awkward against mobile and large enemies. Her own damage is low, so she can't replace an off-field damage dealer.

On the banners: Diona is one of the 4★ characters in the first phase of 7.1 (until October 13) — a convenient time to pick up her constellations.
