Diona build recommendations
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
Prefered over Favonius at higher refinements for consistency and when batterying another cryo unit.
It is recommended to build some Crit Rate coverage to have a higher chance of triggering bow passive for energy.
This bow will be your best choice for stronger shields, but it reduces Diona's burst uptime significantly due to having no Energy Recharge on her weapon.
Regarding Artifact Sets
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.
Provides both ER and HP which are both valuable for a support diona, increasing ult uptime and healing strength respectively.
Regarding Main Stat Priority
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.
