Diana Strengths & Weaknesses

High Damage Scaling Through Discard

Diana excels at chaining Discard effects, which repeatedly trigger Extra Attacks. This allows her to stack damage quickly and overwhelm targets through continuous follow-up hits.

Low Cost Cards

With Quietus, Diana can generate Heart Bullets and apply debuffs without consuming Cost, enabling a highly efficient playstyle. This makes her strong in longer fights where resource management is crucial.

Stack Reset Limits Burst Windows

Flutters reset each turn, meaning Diana must continuously rebuild stacks to maximize damage. This can make her burst less consistent compared to characters with immediate high-damage output.

Reliance on Setup

Her full damage potential depends on properly applying Resonance as well as maintaining a steady Discard and Draw cycle. Poor hand flow or missed setup can significantly reduce her effectiveness.

How To Use Diana?

Consistently Use Quietus

Quietus allows you to generate Heart Bullets and apply Resonance without consuming Cost when Discarded. By triggering it early, you can establish your damage setup while preserving resources for later turns.

Maintain a Discard Cycle

Diana relies on continuously Discarding and Drawing cards to keep her hand active. By cycling through Bullet cards with built-in Discard effects, you can sustain pressure and avoid downtime between attacks.

Trigger Extra Attacks with Resonance

Each time a Discard effect is activated, Diana unleashes Extra Attacks on enemies affected by Resonance. By maintaining this debuff, you can stack multiple hits and rapidly increase overall damage output.

Build Flutter for End-of-Turn Damage

By performing actions throughout the turn, Diana accumulates Flutter stacks. These stacks enhance her end-of-turn Extra Attack, allowing you to deal significant damage especially against high-HP targets.

Aim for 2 Manifest Ego

Character Profile

Race	Human
Birthday	February 18
Gift	Milky Way Harmony
Affiliated Faction	The Holy Crusaders

The love-spreading idol

While given the title of archpriest, Diana does not have the same authority as others of her stature, making her closer to an honorary member. People often regard the Holy Crusaders as a rigid and silent order, but Diana serves as the figurehead who defies that image. All for the happiness of others, and for the sake of love.
