Diona is Monstadt's resident cat girl and a prodigal bartender whose talents stem from a blessing from the Spring Fairy, despite her distaste for all things alcohol. On the battlefield, Diona is a four-star Cryo Bow user who excels as one of the most versatile support units in the game, with the ability to both protect and heal her allies.
She can be summoned from standard and limited Wish Banners and was given away for free during the Energy Amplifier Initiation Event.
Diona is a versatile support who can protect her allies with her elemental skill. Pressing it will create a shield and fire two projectiles dealing cryogenic damage. During this time, the hold will fire five projectiles and increase the shield damage absorption bonus by 75%. The shield remains active even when Diona is off-screen and can protect characters from all types of damage, but is significantly more effective against cryogenic damage.
On the other hand, Diona's Elemental Burst creates an AoE field that continuously deals cryogenic damage and heals nearby characters. Diona can be built to lean on her protective or healing abilities, or a good balance of both.

Diona is best deployed with a bow with an energy recharge sub-stat to offset the 80 energy cost of her elemental burst. His best-placed weapon would be the Sacrificial Bow, which gives an energy recharge sub-stat. Her passive can reset the wearer's elemental skill cooldown, increasing the availability of Diona's shield.
An alternative four-star weapon would be the Favonius Warbow. Of the five stars, go for the Elegy for the End, which helps build energy recharge for a healing-focused Diona. Of the three-star options, the Recurve Bow is the best choice for its HP-focused stats, making it ideal if you want to build Diona as a shield.
There are two Artifact combinations that are also suitable for Diona's kit. One would be the four-piece Noblesse Oblige, which is especially useful when you want to focus on healing Diona:
- Two Piece: Elemental Burst Damage +20%
- Four Pieces: Using an Elemental Burst increases the Attack of all party members by 20% for 12 seconds. This effect cannot stack.
Another great option is a combination of two sets of artifacts that boost both Diona's shield and healing abilities:
- Tenacity of the Millelith in two parts: HP +20%
- Emblem of Fate split in two parts: energy recharge +20%
For artifact stats, consider giving Diona as much HP as possible to make her shield stronger. If you're using a weapon with no energy refill, cast some of this stat to help with its Elemental Burst uptime. Giving him a Healing Bonus Circlet will also increase his healing ability.
Best team for Diona
As an all-around assist, Diona is easy to fit into any team that's struggling to survive. But if you want to get the most out of her Cryo element, consider putting her on Permafreeze teams. These include Hydro applicators like Mona, Barbara, Xingqiu, and Sangonomiya Kokomi, and Cryo Damage dealers like Ganyu, Kamisato Ayaka, Kaeya, and Eula.
