How to Play Esther
Dust Cloud Makes Weak Enemies Stop Targeting You

While standing inside the Dust Cloud generated by Esther's Special Skill, nearby weak enemies are inflicted with "Confused." Enemies under the Confused effect lose the ability to detect Esther, meaning she can maneuver safely even when surrounded by a large group.
Powerful Basic Attacks from Within the Dust Cloud

Esther's Basic Attacks are enhanced while she is inside the Dust Cloud. Combined with the Confused effect, her exceptional performance in group fights is one of her biggest strengths, despite not being a Fighter class.
High-Multiplier Ultimate Skill for Massive DMG

Esther's Ultimate Skill boasts an extremely high DMG multiplier, making it a simple yet devastating skill. When the boss is in a Stagger state, the Assassin Class bonus further increases DMG output, so make sure to land your Ultimate Skill for massive damage.
Support Skill Contributes DMG Even When Off the Field

Even while tagged out, Esther can continue to deal DMG via her Support Skill. The trigger condition is simply an ally attacking an enemy, which is extremely lenient, so there is little need to keep Esther on the field continuously — making her easy to fit into any team composition.
Esther Best Team Comps
Esther Best Team Comp
Esther | Flare | Jiwon |
A team comp built around the Esther and Jiwon combo. For the remaining slot, it's recommended to use a Destroyer or attacker that matches the enemy's Elemental Weakness. Flare's Ultimate Skill DEF Reduction effect is particularly strong in this setup.
Esther Best Monsterlings
Rank Effects that boost their own damage output are recommended
Nokjung | Gulgak | Behemo-wolf |
For Esther's Monsterlings, Rank Effects that boost Wind DMG and Crit-related stats are recommended. Esther's attacks hit multiple times, making it easier to meet conditions like "Landing a critical hit" or "landing 10 Basic Attacks" even with moderate Crit Rate.

Profile
| Esther is a maid employed at the Maid & Clover Inn. She can usually be found with a broom in hand and spends most of the day sweeping floors. She won't respond to anyone with more than a few words or chat about anything outside of official business, so don't let the way she's dressed get your hopes up about a warm welcome. In fact, some people have even said that the way she wields her broom seems awfully icy and hostile... and they're probably not wrong about that. |
