Diona is a 4-star Cryo Bow wielder who functions as a versatile Support specializing in defensive utility through her shields and healing. Her kit revolves around creating a Cryo shield with her Elemental Skill, Icy Paws, which absorbs damage based on her Max HP, and providing field healing and Cryo application with her Elemental Burst, Signature Mix. With the new Stellar-Conduct buff, Diona gains additional team value in updated compositions by helping to generate and maintain the Polestar Field with her rapid Cryo application. This Diona build guide covers her complete build optimization, including her talent priorities, recommended weapons and artifacts, the best team compositions, and her constellation value analysis.

Diona Gameplay
Diona’s gameplay centers around her Elemental Skill, Icy Paws, which allows her to fire icy projectles at opponents. These Icy Paws deal Cryo DMG and create a protective shield upon hit, and the shield's damage absorption increases based on Diona's Max HP and the number of paws that hit a target. This makes Diona a strong defensive Cryo Support who provides reliable shielding and utility while allowing another character to stay safely on-field.
Her passive talent increases character Movement SPD and decreases Stamina Consumption while protected by her shield, giving her extra value in fast-paced teams. However, her main build still focuses on HP%, Energy Recharge, and Healing Bonus, since most of her utility comes from her Skill's shield strength and her Burst's healing.
Her Elemental Burst, Signature Mix, deals AoE Cryo DMG and creates a Drunken Mist zone on the field. While this zone periodically deals Cryo DMG to enemies, its main value comes from continuously regenerating the HP of active characters inside it. While her Burst adds great survivability, Diona’s main utility still comes from her shield, making her Elemental Skill the most important part of her overall performance.
Upcoming Stellar-Conduct Buffs (Version 6.7)
In the upcoming Version 6.7 / Luna VIII update, Diona receives powerful direct enhancements to her kit that heavily synergize with the new Stellar-Conduct mechanic. These updates introduce a brand-new Additional Talent called Choice Treasures. Within 20 seconds after using her Elemental Skill, Icy Paws, Diona will automatically fire off three additional Icy Paws whenever nearby party members trigger Superconduct, Stellar-Conduct, or Cryo Swirl reactions. While these extra paws cannot generate Elemental Particles or create a new shield upon hit, they can trigger once every 3.5 seconds, dramatically increasing her off-field Cryo application.
Furthermore, her final constellation receives a massive buff, as seen in her enhanced Cat's Tail Closing Time (Constellation Lv. 6). While retaining her original healing bonus and 200 Elemental Mastery buffs, Diona now permanently grants herself a 25% Max HP increase. Additionally, any characters standing within her Signature Mix radius will now deal 40% increased Superconduct, Stellar-Conduct, and Cryo Swirl Reaction DMG.
Overall, these upgrades significantly elevate Diona's tier as a supportive anchor. By passively ramping up reaction damage and auto-firing Icy Paws to maintain Cryo auras, Diona transitions seamlessly into a premier enabler for physical, Swirl, and modern Stellar-Conduct team compositions.
Diona Talent Priority
Diona’s talent priority heavily focuses on her Elemental Skill, since most of her utility comes from her shield strength. Her Elemental Burst is also important for providing stronger healing windows, while her Normal Attack has very low priority in most builds.
| Talent | Priority |
| Elemental Skill (Icy Paws) | ★★★★★ (Highest) |
| Elemental Burst (Signature Mix) | ★★★★ (High) |
| Normal Attack (Katzlein Style) | ★★ (Low) |
Elemental Skill – Icy Paws
Level her Elemental Skill first and take it as high as possible. Diona’s main utility comes from her Icy Paws, which create a protective shield upon hitting opponents and periodically absorb Cryo DMG and incoming attacks. Since her gameplay revolves around maintaining a strong shield and generating consistent off-field Cryo particles, this talent has the biggest impact on her overall supportive capabilities.
Elemental Burst – Signature Mix
Level her Elemental Burst second. Signature Mix deals AoE Cryo DMG and creates a Drunken Mist zone, giving Diona strong periodic healing and elemental application during her rotation. With the Stellar-Conduct buff, her Burst remains incredibly valuable because it helps lock down opponents in the reaction zone, allowing her to passively trigger supportive buffs and maintain team wide damage multipliers.
Normal Attack – Katzlein Style
Level her Normal Attack last. Diona’s Normal and Charged Attacks can deal Cryo DMG when fully charged, but they are not her main source of utility in most team compositions. Since she is usually played as an off-field Support, players should prioritize her Elemental Skill and Elemental Burst before investing heavily into her Normal Attack.
Diona Best Weapons
Diona’s best weapon depends on availability and team composition. For Support builds, Energy Recharge or HP% weapons are ideal. Her best supportive weapon and other strong 5-star Bows provide her best performance, while several 4-star options remain solid alternatives for players without premium weapons.

Diona Best Team Compositions
Diona works best as a defensive Cryo Support supported by characters who can improve her Icy Paws utility, enable Cryo reactions, or increase her overall team utility. Her most common teams focus on Superconduct, Freeze, and Melt setups, while the new Stellar-Conduct buff opens a new team direction built around Polestar Field.
1. Stellar Conduct Team
Diona excels in Stellar-Conduct teams by using her Icy Paws to trigger the Polestar Field. Her Signature Mix burst provides a 40% reaction damage bonus to Superconduct, Cryo Swirl, and Stellar-Conduct. This elevates her into a top-tier offensive enabler, maximizing the team's elemental output while keeping characters alive.
| Main DPS | Sub-DPS / Enabler | Support / Flex | Sustain |
Sandrone (5★) | Yae Miko (5★) | Beidou (4★) | Diona (4★) |
Wriothesley (5★) | Sandrone (5★) | Fischl (4★) | Diona (4★) |

2. Diona Freeze Team
Diona anchors Freeze teams by providing strong shields and healing while consistently applying Cryo to keep enemies permanently frozen alongside a Hydro enabler.
| Main DPS | Support 1 | Support 2 | Sustain |
Ayaka (5★) | Shenhe (5★) | Kazuha (5★) | Diona (4★) |

Diona Constellations (Updated)
Diona is already a complete Cryo Support at C0, so her constellations are not required to make her work well in Superconduct, Freeze, Melt, or Stellar-Conduct teams. Unlocking constellations mainly increases her Icy Paws shield absorption, improves her Energy management, and strengthens her team support value. With the Stellar-Conduct buff, her key constellations gain more value by improving Cryo DMG, Stellar-Conduct DMG, Elemental Mastery bonuses, and her enhanced off-field utility windows.
Constellation Performance
| Constellation | Rating | Why it's good |
| C1 | ★★☆☆☆ | Regens an extra 15 Energy for Diona after Signature Mix ends, improving her burst uptime and team healing consistency, but the overall mechanical change is still limited. |
| C2 | ★★★★★ | Diona's best early upgrade. It greatly improves her support value by strengthening her shield's absorption by 15% and providing crucial co-op team protection by shielding nearby allies during combat. |
| C4 | ★☆☆☆☆ | Reduces Diona's charge time for aimed shots by 60% within her Signature Mix radius, making it a very niche and mostly negligible offensive upgrade for her own kit in typical teams. |
| C6 | ★★★★★ | Diona’s strongest constellation. It permanently upgrades her support capabilities, providing a massive 200 Elemental Mastery boost for active characters alongside a powerful 40% increased reaction damage bonus, making it the ultimate investment for dedicated players and long-term Stellar-Conduct teams. |
Constellation Effect
Constellation | Effect |
| C1 | ''A Lingering Flavor'' Regenerates 15 Energy for Diona after the effects of Signature Mix end. |
| C2 | ''Shaken, Not Purred'' Increases Icy Paws' DMG by 15%, and increases its shield's DMG Absorption by 15%. Additionaly, when paws hit their targets, creates a shield for other nearby characters on the field with 50% of the Icy Paws shield's DMG Absorption for 5s. |
| C3 | ''A-Another Round?'' Increases the Level of Signature Mix by 3. Maximum upgrade level is 15. |
| C4 | ''Wine Industry Slayer'' Within the radius of Signature Mix, Diona's charge time for aimed shots is reduced by 60% |
| C5 | ''Double Shot, On The Rocks'' Increases the Level of Icy Paws by 3. Maximum upgrade level is 15. |
| C6 (as per 6.7 Buff) | ''Cat's Tail Closing Time'' Characters within Signature Mix's radius gain the following effects based on their HP levels:
Additionally, Diona's Max HP is increased by 25%, and characters within Signature Mix's radius deal 40% increased Superconduct, Stellar-Conduct, and Cryo Swirl Reaction DMG. |
Conclusion
This comprehensive guide demonstrates Diona’s position as one of the most reliable defensive Cryo Support characters in Genshin Impact. Her consistent shielding through Icy Paws, powerful healing from Signature Mix, and strong Cryo reaction synergy make her a flexible choice for Superconduct, Freeze, Melt, and Stellar-Conduct team compositions. While her Elemental Burst has a high Energy Cost, her off-field utility output and flexible rotations allow her to perform well when supported by the right weapons, artifacts, and teammates.
With the Stellar-Conduct buff, Diona receives important enhancements that improve her value in teams built around Polestar Field. The addition of stronger Icy Paws interactions, HP-based shielding, and extra reaction damage bonuses gives her a higher utility ceiling while keeping her core gameplay focused on Signature Mix, Cryo application, and team survivability. These updates help Diona stay relevant in the evolving meta without changing her identity as a powerful Cryo Support.
