Diona is mainly used as an off-field support, which means she will generally be brought on-field to apply shields using Icy Paws. You will want to hold the skill down to activate the shield in order to get the additional 75% damage absorption bonus. Holding the skill will create a much better shield

Talents & Constellations

Normal AttackKtzlein Style

Performs up to 5 consecutive shots with a bow.

Normal Attack
Elemental SkillIcy Paws

Fires an Icy Paw that deals Cryo DMG to opponents and forms a shield on hit. The shield's DMG Absorption scales based on Diona's Max HP, and its duration scales off the number of Icy Paws that hit their target. {LAYOUT_MOBILE#Tap}{LAYOUT_PC#Press}{LAYOUT_PS#Press} Rapidly fires off 2 Icy Paws. Hold Dashes back quickly before firing 5 Icy Paws. The shield created by a Hold attack will gain a 75% DMG Absorption Bonus. The shield has a 250% Cryo DMG Absorption Bonus, and will cause your active character to become affected by Cryo at the point of formation for a short duration. When she first started bartending, Diona found that no matter how much ice she put in her cocktails, it would never do a drunkard any harm. That all changed when she received her Vision — now she can form ice cold enough to cause severe brainfreeze. Five out of five stars!

Elemental Skill
Elemental BurstSignature Mix

Tosses out a special cold brew that deals AoE Cryo DMG and creates a Drunken Mist in an AoE. Drunken Mist ·Deals continuous Cryo DMG to opponents within the AoE. ·Continuously regenerates the HP of characters within the AoE. A horrific mix that even Diona considers inhumane. The horrifying foretaste should be left for one's opponents. It has a crisp aftertaste, but unfortunately, one can only feel it on one's nose and skin.
