Strategy
She’s one of the harder super bosses in the Labyrinth of Chaos. Fight her like you would any other super boss. Stack Vicarious Clara, stack your stats, debuff hers. Then attack her. However, you want to keep these things in mind: Check here and here for detailed information on all the super bosses and everything you can make use of to defeat them.
 * She is completely immune to Physical, Bio and Sonic attacks. Any certain Hit attack that deals those types of damages will heal her, making Makina skills inefficient. However, she’s weak to most elements, making Magical skills the best source of damages.
 * She possess a self-buff reflecting Magical attacks. Dispel (Priest) counters it.
 * She can inflict both party wide Instant Death and Ascension. Bringing a Kitsune Geisha for her Anti-Death Song is vital to countering this.
 * She also has certain hit attacks which inflict Burn, Shock and Freeze. Vicarious Clara can deal with these attacks, as it’ll prevent them from landing in the first place.
 * She has an attack which inflicts single target Bind. Again, Vicarious Clara should be able to protect you from this.
 * She can be Slowed/Stopped and debuffed, making Sea Palace Maikos and Taoist effective.
