How do I optimize Diona's support build in Genshin Impact?

Optimizing Diona's support build in Genshin Impact involves focusing on her role as a healer and shielder while also considering her ability to provide energy regeneration and Cryo application. Diona is a versatile character who can fit into many team compositions, especially those that benefit from Cryo reactions or need a reliable healer and shielder. HereÔÇÖs a detailed guide on how to optimize her support build.

First, letÔÇÖs discuss DionaÔÇÖs mechanics. DionaÔÇÖs Elemental Skill, Icy Paws, fires icy claws that deal Cryo damage and create a shield based on her max HP. The shieldÔÇÖs strength scales with her HP, making HP a crucial stat for her. Her Elemental Burst, Signature Mix, creates a healing field that deals Cryo damage over time and heals characters within it. The healing scales with her max HP, so again, HP is vital. Additionally, DionaÔÇÖs passive talents can provide energy regeneration and stamina reduction, making her even more supportive.

To optimize DionaÔÇÖs support build, start by focusing on her talents. Prioritize leveling her Elemental Burst, as it is her primary healing ability. Next, level her Elemental Skill to increase her shield strength. Her normal attack talent is less important for a support build, so you can leave it at a lower level. If you have constellations, C2 increases the shield strength and damage absorption, while C6 boosts her Elemental Burst by increasing Elemental Mastery for characters within the healing field.

For artifacts, the best set for Diona is the 4-piece Noblesse Oblige. This set increases her Elemental Burst damage and provides a 20% attack boost to the entire team after using her Burst. If you already have another character using Noblesse Oblige, consider the 4-piece Maiden Beloved set, which increases healing effectiveness. For main stats, prioritize HP% on the Sands, Goblet, and Circlet. Sub-stats should focus on HP%, Energy Recharge, and Crit Rate if you want her to trigger Favonius WarbowÔÇÖs passive more consistently.

Weapon choice is also crucial. The best weapon for Diona is the Sacrificial Bow, which has a chance to reset her Elemental Skill cooldown, allowing her to generate more energy and maintain her shield more consistently. If you donÔÇÖt have Sacrificial Bow, the Favonius Warbow is a good alternative, as it generates energy particles when you land a critical hit. For a more budget option, the Recurve Bow increases her HP, which boosts her healing and shield strength.

In terms of team composition, Diona works well in teams that benefit from Cryo reactions or need a healer and shielder. For example, in a Freeze team with characters like Ayaka or Ganyu, Diona provides Cryo resonance, which increases Crit Rate against enemies affected by Cryo. She also works well in teams that need a battery for Cryo characters, such as Eula, as her Elemental Skill generates Cryo particles. In a Melt team with characters like Diluc or Hu Tao, Diona can provide shields and healing while also applying Cryo for Melt reactions.

When using Diona in combat, make sure to use her Elemental Skill before her Burst to generate energy and create a shield. This will help protect your team while her Burst heals them. If you have Sacrificial Bow, use her Elemental Skill twice in a row to maximize energy generation and shield uptime. Always position her Burst in a way that covers your active character, as the healing field is stationary.

Common mistakes to avoid include neglecting her HP stat, which directly affects her healing and shield strength. Also, avoid using her Elemental Skill without considering the shieldÔÇÖs duration, as it can leave your team vulnerable. Another mistake is not using her Burst frequently enough; make sure to use it as soon as itÔÇÖs available to keep your team healthy.

Advanced techniques include using DionaÔÇÖs Elemental Skill to apply Cryo before switching to a main DPS for reactions. For example, in a Melt team, use DionaÔÇÖs Skill to apply Cryo, then switch to Diluc or Hu Tao to trigger Melt. Additionally, if you have C6, position your team within her Burst to benefit from the Elemental Mastery boost, which can significantly increase reaction damage.

In summary, optimizing DionaÔÇÖs support build involves focusing on her HP, Energy Recharge, and Cryo application. Use the Noblesse Oblige or Maiden Beloved artifact sets, prioritize her Elemental Burst and Skill talents, and equip her with Sacrificial Bow or Favonius Warbow. Pair her with characters that benefit from Cryo reactions or need a healer and shielder, and use her abilities strategically to maximize her support potential. By following these steps, you can make Diona a valuable asset to your team.
