CONSIDER IT — extremely strong in PvP against opponents who lean on one main Attacker, but in Campaign/Raid she's mainly useful only when the boss is Attacker-class; not a universal pick for everyone.

Skill Investment Priority
Skill investment roadmap (Skill 1/Skill 2/Burst): 1/1/1 → 4/1/4 → 7/1/7 → 10/1/10. Why: Burst (her main damage) and Skill 1 (dispel + crit damage) are her core value; Skill 2 only triggers when an ally goes down, so it's lowest priority.
Strengths & Weaknesses
Strengths
- Her burst specializes in melting enemy Attackers with massive damage (1310% ATK, more while Concealed) — one of the strongest single-target bursts around.
- Skill 1 dispels enemy buffs at the start of the fight, both disrupting the opponent and self-buffing her own crit damage.
Weaknesses
- Very low normal-attack multiplier (5.1% ATK) — she contributes almost nothing outside her burst.
- Concealment breaks the instant she takes damage, so it's not a true damage-immunity shield.
