The Best Diona Build for 2026 in Genshin Impact—Starlight, Weapons, and Teams
After unlocking “The Witch’s Prophecy,” Diona gained additional Cryo attacks, and at Constellation 6, she received team buffs through Stardust. She now combines shielding and healing with bonuses to Elemental Mastery and Star Reaction damage. In this guide, we’ll break down Diona’s new build in Genshin Impact and the best teams to pair her with.
How to Unlock Star Shard for Diona
Level Diona up to Level 70 and complete the “Random Revelations” quest, which becomes available after the Archon Quest “Song of Dragon Freedom.” Then open the “Witch’s Prophecy Box” in the “Tools” section and select Diona’s quest, “Signature Cocktail Instructions.” If you’ve already completed the introductory quest for another character, you don’t need to repeat it.
A new passive talent allows Diona to release additional Frost Claws from her pocket. For 20 seconds after using the skill, they trigger when Superconduct, Cryo Dispersion, and their Star variants—no more than once every 3.5 seconds. These attacks apply Cryo but do not generate a shield or energy particles.
The main enhancements unlock at S6:
- Dione’s maximum HP increases by 25%.
- The active hero within the ultimate’s area of effect gains 200 MS if their health is above 50%.
- When in the corresponding Radiance state, the ultimate’s area grants a 40% damage bonus to Star Superconductor or Star Scatter.
Diona herself does not convert regular reactions into Stellar ones; this requires a suitable ally such as Odette, Cryo GG, Sandrone, Miti, and other Cryo and Electro 5-star characters from the Snow region.
Diona’s Best Build—Weapons and Artifacts
Diona is a healer and tank. She needs energy regeneration for her ultimate and HP for her shield and healing. Her 200 MS bonus is fixed, so there’s no need to build her own Elemental Mastery for this boost.
Best Artifacts:
- 4x Heart of Horn—if there’s no other carrier on the team. Diona must activate the Stellar Reaction herself or deal damage with it to trigger the bonus; a single Cryo application isn’t enough. It’s especially convenient to give the set to Odette if she’s on the team.
- 4x Millelith’s Resilience—increases the team’s attack power and shield durability. The extra points allow you to refresh the effect on the fly, though there may be brief pauses between activations.
- 4x Ceremony of the Ancient Nobility—for a damage dealer who needs attack power, if no one else is wearing the set yet.
- 4x Instructor—provides the team with an additional elemental mastery, but at the cost of stat reductions due to its 4-star rarity.
- 2+2 for HP and Energy Regeneration—a temporary option until you obtain the full set.
Stats:
- Watch: Energy Regeneration / HP.
- Goblet: HP.
- Crown: HP / Critical Chance with the Favonia Battlebow.
- Additional stats: Energy Regeneration, HP%, Critical Chance for Favonia, Flat HP.
You can equip the Crown with the healing bonus if HP recovery is more important. However, it does not strengthen the shield.
To start, aim for roughly 180–250% energy regeneration, then adjust the build for your team. Requirements depend on the number of Cryo allies, the Favonia weapon, and how often you use your ultimate. At S6, it’s best to build her so she has enough for an ultimate every rotation.
Best Weapons:
- Elegy of Doom—provides energy regeneration for Dione, Elemental Mastery, and attack power for the entire team.
- Melodies of the Gentle Wind—a bow for Star Reactions. Provides energy regeneration via its passive and enhances the team’s Star Radiance. At high Ascension levels, it can outperform Elegy of Doom.
- Favonia Battle Bow — a practical option when energy is low. Dion must land a critical hit to activate the passive.
- Ceremonial Bow—allows you to reuse a skill and gain additional Cryo particles. Especially useful for charging another Cryo hero’s ultimate.
- Curved Bow—an affordable HP-focused option if energy regeneration is already maxed out.
Best Teams for Diona with Starlight
In these compositions, it’s best to have Diona at Starry Radiance C6. Her buffs are designed for an active hero within the ultimate’s area, so use her shortly before the main damage dealer steps out. But even without the sixth constellation, Diona is capable of supporting Starfall squads.
Best squads:
- Sandrone, Odette, Yae Miko, Diona—Odette boosts the reaction, Yae Miko maintains the Electro status, and Diona defends and buffs Sandrone.
- Sandrone, Qi Qi, Bei Dou, Dion—a team with high defense. Bei Dou’s S6 and Dion’s S6 are especially useful.
- Saino, Odette, Yae Miko, Diona — a team with Saino on the field. You can replace Odette with the Cryo Traveler.
- Mizuki, Odette, Sucrose, and Diona—Odette triggers the reaction, Sucrose adds elemental mastery, and Diona provides a shield and buffs.
- Mizuki, Cryo Traveler, Saccharose, and Diona—a more accessible option without Odette.
- Vesna, Odette, Faruzan S6, Diona — a team with Vesna as the main damage dealer and buffs from three supports.
Diona’s ultimate lasts 12 seconds and has a 20-second cooldown. Therefore, in short Star Scatter rotations, it’s sometimes more effective to use it every other rotation.
Frequently Asked Questions (FAQ)
Для щита, лечения и дополнительных Крио атак — нет. Однако 200 МС и бонус к урону Звёздных реакций доступны только на С6.
Для обычной роли саппорта приоритетнее восстановление энергии и HP. Количество МС, которое она передаёт через С6, не зависит от её собственной характеристики.
Боевой лук Фавония — для энергии команды, Церемониальный лук — для повторного навыка и Крио частиц. Для усиления Звёздного блеска также подходит Напевы нежного ветра.
Проверьте С6, положение активного героя и его здоровье: он должен стоять внутри области ульты и иметь больше 50% HP.
Навык — для прочности щита, затем ульту — для лечения. Обычные атаки саппорту не нужны. Уровни талантов не увеличивают фиксированные бонусы С6.
