Black Beacon Viola was born into a musical family, showing strong musical talent from a young age and excelling in playing techniques, being called a genius. As a 5-star character, many players who successfully draw her do not fully understand her. Below is an introduction to her skills, an analysis of her strength, to help players deepen their understanding of her, thereby better utilizing her on the battlefield.

Her normal attack has four segments, and holding down the normal attack will trigger a heavy hit. Her passive ability is that when both the original tone and the dissonant tone fields exist simultaneously, all fields will generate an afterecho every 1.1 seconds, dealing follow-up damage to enemies. Her entrance skill, upon switching onto the field, continuously slashes nearby enemies, causing regular damage.

Her "Deep" ability creates an original tone field at a specified location for 15 seconds; holding down can create two at once. The original tone field deals damage to enemies within its range every 2 seconds. Her "Like a Thorny Bow" ability slashes in the target direction, causing regular damage to enemies and converting any touched original tones to dissonant, and vice versa.

The dissonant field also deals damage to enemies within its range every 2 seconds. A maximum of two fields can exist on the field at any time. Her ultimate skill initiates a performance, releasing two electric grids to sandwich and deal finishing damage to enemies. Her first talent refreshes the duration of all fields on the field when the afterecho spreads.

When multiple fields are hit at once, only one will be converted. Her second talent, when her health first drops below half, uses the spread of the afterecho to restore a certain amount of health. Her third talent increases her own attack power by 5%.

Overall, Black Beacon Viola is a decent sub-DPS. She can achieve high off-field damage by summoning two fields during combat and changing one before leaving the field. This makes her a perfect fit for various teams, making her well worth developing.
