As a support, Диона is typically used for three things: Shielding, Healing, and Крио particle generation. Pairing Diona with Крио damage dealers such as Аяка, Гань Юй, and Эола allows you to funnel energy into them while providing them a shield. Weapons such as and greatly increase her potential as a battery.
Диона's Элементальный навык grants a Крио shield which allows cleansing. Every time you swap characters with the shield up, it applies Крио. This acts as a cleanse.
Относительно выбора оружия:
Церемониальный лук: Preferred over at higher refinements (R3+) when batterying another Крио character.
Сердечные струны дождя: One of the best choice for stronger shields, however the Восстановление энергии and useful passives of other weapons will generally make it a suboptimal pick.
Изогнутый лук: One of the best choice for stronger shields, however the Восстановление энергии and useful passives of other weapons will generally make it a suboptimal pick.
Каденция одиночества: One of the best choice for stronger shields, however the Восстановление энергии and useful passives of other weapons will generally make it a suboptimal pick.
Относительно артефактов:
Full Stack HP% is recommended if you want stronger shields but a weaker heal. You can use Бонус лечения Circlet if you want a nice balance between the two.
Наборы артефактов
Церемония древней знати
(4): This set provides a teamwide Сила атаки% buff while also increasing Взрыв стихии damage. Диона does not have the best uptime on this set, however, she may be the best option to use this set.
Инструктор
(4): This set is a niche option for Диона. It can be considered in teams which value Мастерство стихий and where she can trigger a reaction while on-field. Keep in mind that being limited to a 4-star set means your stat potential will be lower.
Стойкость Миллелита
(4): This set is a niche option for Диона. It can be considered in teams including some variants of Гань Юй Заморозка which have shorter rotation lengths, meaning Диона's Взрыв стихии will not be used every rotation, and where you can snapshot the Сила атаки% buff onto Гань Юй's Взрыв стихии.
Сабстаты
Шанс крит. попадания: Шанс крит. попадания требуется только при использовании оружия Фавония.
Относительно приоритета талантов:
Prioritise whichever your Диона is geared for (shielder or healer), if built for a balance between the two, level both equally.
