5★ WIND Assassin Melee

Analysis

Powerful Assassin with high burst windows. AoE is fantastic but tied to a cooldown-heavy circle. Shines when enemies are staggered; slightly more niche in sustained Rift content.

Tier Position

World / Path T0
Conquest T0
Dimensional Rift T0.5

Game Modes

World / Path T0
Esther's continuous wind AoE while in her field is excellent for clearing groups, and her auto attacks sweep enemies while she's in it. The 15-second cooldown is a real limitation, but between cooldowns she's still an effective sub-DPS. Particularly good against weaker enemies that melt quickly.
Conquest T0
Assassins gain bonus DMG against staggered enemies, and Esther's Ultimate + Special Skill deal most of their damage in a concentrated window — perfectly timed to abuse Stagger. A strong Conquest pick as long as your team can handle the Neutralization DMG side.
Dimensional Rift T0.5
Esther's AoE circle is potent but has a high cooldown that limits her sustained output in Rift. She's still viable — her burst windows are impressive — but the inconsistency between rotations keeps her slightly below S tier in this mode.

Pros

3
Continuous wind AoE field clears groups extremely efficiently while it's active
Assassin class bonus DMG against staggered enemies amplifies burst windows
Ultimate and Special Skill combo delivers exceptional concentrated damage

Cons

3
15-second cooldown on her field creates significant gaps in AoE output
Full burst window depends on teammate Neutralization DMG to stagger the boss
Rotation inconsistency keeps her slightly below the very top in Rift
