Diona is a playable character in Genshin Impact, and despite being a bartender at the Cat's Tail tavern, she's also a capable fighter. To help you understand just how useful her kit is, here's the best Diona build you can find.
Diona, but DIO
Diona is a 4-star character in Genshin and she is one of the best supports you can build. She offers a lot of value with her big heals, damage boost, and useful shields. Diona is a flexible unit with good Cryo application, which makes her perfect for many teams. To make the most of her kit, it is crucial to equip her with the right weapons and Artifacts and level up the right Talents.
As a Cryo support, Diona uses a bow as her weapon of choice. While she scales with Cryo damage, Diona's value comes from her utility, heals, and damage buffs. This means you'll want to equip her with bows that provide even more utility and defensive stats to maximize her kit. Fortunately, Diona has a ton of free-to-play options, but also decent options for light spenders.
