Dian Analysis

Could Extend Your Main Attacker's Lifespan

Heart of Servitude

Dian is most useful as a buffer for your main Attacker because of her skill 'Heart of Servitude,' which increases both her EVD and the EVD of the witch with the highest ATK stat in the party (in this case, it should be your main Attacker).

Her other skills are lackluster. Cursed Bullet in particular actually depletes her HP to deal damage instead of just attacking her enemies. Her other skill, Piercing Shot, would be okay if fights lasted more than 2-3 turns so that its 'Bleed' debuff could be used to its full damage potential. Otherwise, it doesn't have that much utility.

Dian Best Runes

Give Dian DEX, ATK, EVD, & HP Runes

If you have the resources, give Dian runes that augment her DEX, ATK, and SPD. You can give her PM. Def Break runes too, though if you need them for someone else, then give it to them. You won't need Dian to deal heavy damage.

For defensive runes, make sure to give EVD, HP, CRIT RES, and Debuff RES runes. HP runes to make sure Dian lives a little longer if she uses her Cursed Bullet skill, and EVD so she could stack that on top of the EVD boost she'll get with Heart of Servitude.

Dian Best Team Comps

Critical Survival Team (PvE)

Dian is a bit versatile in that you just need her for one thing - to make sure your main attacker evades a very devastating attack and lives at least a couple or more turns. So replacing anybody who isn't critical to have in your party with her would be okay.

Heart of Servitude	Passive Buff	-

Skill Effect

Level 1 (Unlocks by level 41) Dian provides support with all her heart and devotion.

Servant’s Expertise	Passive Buff	-

Skill Effect

Level 1 (Unlocks by level 61) In order to save as many friends as she can, even if must act alone, Dian stays on the battlefield until the very end. If she is attacked, and her remaining HP percentage falls below 40% while the number of allies who are alive are 2 or more, this skill grants ［Invisibility］to Dian (cannot be dispelled). At the start of each turn or when an ally is defeated, if the number of allies who are alive becomes 1 or less, ［Invisibility］is dispelled. This skill activates only 1 time per battle.
