| Review | |||||||||
| - A Physical attacker specializing in status effects, inflicting Poison and Bleed - Both skills are AoE 2-hit attacks, also useful for farming - Especially recommended for early game as she is useful in Water/Dark/Light Particle Dungeons - Her Camouflage, which makes her hard to defeat, is also a strength - Also good that she gains a Pierce effect with Skill Enhancement | |||||||||
