Strategy
Basic Labyrinth superboss strategy apply there, however, a few points of note: Check here and here for detailed information on all the superbosses and everything you can make use of to defeat them. A battle against her with only part 1 equipment, no Crisis Hairpin and no stats buffed can be seen here.
 * Most of her attacks can be dodged/reflected.
 * You can inflict silence on her with reflected spell.
 * 75% physical evasion means any such attack needs buff to reliable hit largely Bulleye Song or slow/stop.
 * Only Labyrinth superboss that lacks a form of dispel all.
