Stage 71 ~ 80

Enemy Battle Speed 35,000: It's hard to go fast enough to go first in this stage, so you're going to have to tank some Piercing attacks and then heal. The anti-Pierce skills Repel Pierce and Drain Pierce help a lot. Also, many of the enemy demons take reduced damage from Physical attacks, so a magic-based offense is recommended.; Recommended Demons: 5★ Amaterasu, 5★ Alilat or 5★ Rama.

Stage 81 ~ 90

Enemy Battle Speed 20,000 [Dx2 skill effects disabled]: The same kinds of strategies that worked on the previous 10 stages generally still work, although the level 90 boss is best dealt with by a specialized team. The enemies use Almighty, Piercing Ice and Piercing Physical attacks, so use a team that can nullify all of those.

Starting from Floor 86, several miniboss enemies will show up, usually on the last wave. These minibosses are typically 5★ demons (Grade 80+) and have specialized kits making them harder to deal with. These minibosses do not have Null Mortal though, if you have demons capable of inflicting Mortal such as Alice or Masakado, consider using them in these levels.

Stage 91 ~ 100

Enemy Battle Speed 25,000 [Dx2 skill effects disabled, Item use forbidden.]

From here on out each stage has only one wave, where you fight one boss and 3 adds.

You can potentially clear the stages with an incredibly strong Phys crit team, but if yours is not strong enough you probably have to fall back to repel/drain teams.

insta-killing the adds with Masakado/Alice/White Rider might make your life easier.

The boss, King Frost, nulls every element and has Null Pierce in Hell Shield. Null Pierce also applies to his allies, Black Frost having Null Ice and Dark.

You can only damage him with almighty magic, almighty physical, or fractional damage skills.

The Jack Frost and Black Frost revive every 2 turns, and if all 3 Frosts are alive you get hit with a 5 Elements-piercing Megidolaon at the start of their turn.

Strategies:

Nuke King Frost turn one with Masakado A, Shiva A, Asura Lord, and Skull Knight, clean up the rest afterwards.
Kill the adds with Reiko or Skull Knight (with or without the help of Persephone), have Teal Rama with Null Phys (or have an additional Drain Ice unit alive that casts Tetrakarn every turn), and Brahmastra spam until death.
