Strategy
Basic Labyrinth super boss strategy apply there, however, a few points of note: Check here and here for detailed information on all the super bosses and everything you can make use of to defeat them.
 * Most of her attacks can be dodged/reflected.
 * You can inflict Silence on her with reflected spell which disallows her use of dispel all.
 * 75% Physical Evasion means such attacks need (de)buff to reliable hit, largely Bullseye Song or Slow/Stop.
