Queen Lamia/Labyrinth of Chaos

The alive version of Aria Lamia is, like all the other members of the Cirque du Croix, a boss that can be randomly encountered every 10 floors of the Labyrinth of Chaos on her own.

She can act twice per turn, and riposte by healing herself.

Strategy
With an automatic self-heal, zombifying her will get her killed fast. If you're not fortunate enough to have this status effect at hand, prepare for a battle of attrition, as said heal will make the battle drag on for an horrendously long time. Magical resist is a must-have, as they will prevent her demon eyes from landing. On the offensive side, you will need to take into account her self-heal and her two dances. Make sure your skills are never blocked by her dance. Putting her to sleep isn't quite useful as she will quickly wake up. Freezing her, however, will prevent her from going on the offensive.
