Role: Shielder / Healer / Cryo Battery
Best For: Players who want a flexible Cryo support who can provide shielding, healing, and Energy for Cryo teammates while offering additional reaction support at C6.
1. Recommended Artifacts
4-Piece Noblesse Oblige — A strong general support option when no other teammate is using it, allowing Diona’s Elemental Burst to provide an additional teamwide ATK buff.
Alternative: 4-Piece Song of Days Past can convert her healing into additional damage, while 4-Piece Tenacity of the Millelith is useful in Stellar-Conduct or Superconduct teams after unlocking her Witch’s Revelation Passive.
2. Recommended Weapons
Premium: Elegy for the End
Alternatives: Sacrificial Bow, Favonius Warbow
F2P: Favonius Warbow / Recurve Bow
Sacrificial Bow is especially useful when Diona is supporting another Cryo character because its Skill reset allows her to generate additional Cryo particles. Favonius Warbow provides strong teamwide Energy generation and is particularly accessible because one copy is obtained for free during the Mondstadt Archon Quest.
3. Recommended Teams
Freeze: Kamisato Ayaka + Diona + Furina + Escoffier
Melt: Mavuika + Diona + Citlali + Bennett
Stellar-Conduct: Sandrone + Diona + Yae Miko + Escoffier
Diona can fit into many teams that need defensive support, but she is particularly useful alongside Cryo characters because her Elemental Skill generates Cryo particles while also providing a shield. At C6, she becomes more valuable in reaction-focused teams through her Elemental Mastery and Stellar-Conduct buffs.
4. Main Stats / Substats
Sands: HP% / Energy Recharge
Goblet: HP%
Circlet: HP% / Healing Bonus / CRIT Rate with Favonius
Priority: Energy Recharge until needed → HP% → CRIT Rate with Favonius → HP
Both Diona’s shield and healing benefit from HP, making HP% her primary defensive stat. If using Favonius Warbow, some CRIT Rate is useful to trigger its passive reliably.
5. Playstyle
Use Diona’s Hold Elemental Skill to fire multiple Icy Paws and create her stronger shield. The Skill also generates Cryo particles, making Diona an effective battery for Cryo teammates.
Use her Elemental Burst when healing or its additional buffs are needed, then switch back to the team’s main damage dealer. Prioritize leveling her Skill for stronger shields, followed by her Burst for improved healing.
6. F2P
Diona is very F2P-friendly because Favonius Warbow is obtainable for free and provides both Energy Recharge and additional particles for the team. Recurve Bow is another accessible option when maximizing her HP and shield strength is more important.
F2P players can focus almost entirely on HP and sufficient Energy Recharge rather than expensive offensive stats. Her shield, healing, Cryo particle generation, and core support utility do not require a 5-star weapon.
*StoryBillion Tip: Use Diona’s Hold Skill rather than her Tap Skill when you want a stronger, longer-lasting shield. Sacrificial Bow is especially useful because Diona’s multi-hit Hold Skill has a very high chance of triggering its reset, letting her generate another set of Cryo particles.
