Diona build guide

Diona

Diona function both as a support healer and shielder in the team. Her Elemental Skill (E) provides a shield that scales based on her HP and and also cleanses on-field character from any elemental aura. Apart from shielding, she generally also act as a battery for cryo characters due to the cryo particles that she generates. This becomes even stronger when she’s equipping the Sacrificial Bow. Meta wise, her shielding should offset the need for healing making the 4 piece Noblesse Oblige a more practical set for her.

Support Diona

Her best weapon would be the Sacrificial Bow so that she can use her E twice. This increases the reliability of her shield uptime and doubles her cryo particle generation. For artifact, concentrate on HP% so that she provides a stronger shield. In terms of artifact set, the 4 piece Noblesse Oblige brings more value to the team for its attack buff as her shielding should offset the need for healing. She usually excels with cryo hypercarry such as Eula, Ayaka and Ganyu for her shielding and battery role but is quite flexible.

The shielding Diona puts out should offset the need for healing from her burst. The damage boost from Noblesse Oblige (4) has more practical use. Additionally, her first constellation greatly increases her ultimate uptime, further lowering the healing needed.

As a support, Diona’s typically used for three things; Shielding, Healing, and Cryo particle generation. Pairing Diona with Cryo carries such as Ganyu and Eula allows you to funnel energy into your DPS characters while providing them with quick shields for stagger resistance. Weapons such as Sacrificial Bow and Favonius Warbow greatly increase her potential as a battery.

Regarding Weapon Choices:

Sacrificial Bow: Prefered over Favonious especially at higher refinements due to having better Shield uptime.
Favonius Warbow: You will look to build some Crit Rate coverage to have a higher chance of triggering bow passive for energy.
Recurve Bow: This bow will be your best choice for stronger shields, but it reduces Diona’s burst uptime significantly due to no Energy Recharge on her weapon.

Regarding Artifact Sets:

Noblesse Oblige (4): This set provides an atk buff while also increasing burst damage – this set is usually used with healers because you want to use damage sets on other support units such as Xingqiu or Beidou.
Emblem of Severed Fate (2) Tenacity of the Milellith (2): Provides both ER and HP which are both valuable for a support diona, increasing ult uptime and healing strength respectively.

Regarding Main Stat Choices:

Full Stack HP% is recommended if you want stronger shields but a weaker heal. You can use Healing Bonus Circlet if you want a nice balance between the two.

Regarding Talent Priority:

Prioritise whichever your Diona is geared for (shielder or healer), if built for a balance between the two, level both equally.
