Walkthrough

18F: The Irreversible Spiral Orbit

As the floor's name implies, 18F is chock full of one-way floors. Every path that doesn't lead to the 19F stairs will ultimately lead back to the start of this floor, so be prepared to do a lot of backtracking, especially if you want all the items. The amount of experience from enemies jumps significantly on this floor; expect to gain levels very quickly as you explore. You'll need it for the battle against Rinnosuke.

Notable Enemies

Rabbit Snipers are not only fast, they have an attack called Snipe that often targets the third or fourth character in your party, and can appear in groups of two.

Shub-Nigguraths can use Destroy Magic, which reduces your active party's SP to zero.

Guardians have very high DEF and MND, and decently high HP to go with it. In addition, its powerful attack is often enough to knock out all but the sturdiest tanks, and it even has decent PAR resistance.

If you don't mind returning to the base painfully often, bringing out a couple high-SPD characters and Flandre can help make grinding on this level somewhat easier; firing off a number of multi-hit spells or buffing Flandre's ATK/MAG with the faster characters then firing off a Laveatein can finish off most enemies on this floor before they can get a chance to move (except Peta Grains and Guardians). As mentioned before, be wary of Rabbit Snipers and Shub-Nigguraths (both of whom have appreciably high SPD), who can either kill Flandre or neuter her offensive ability in one turn.

Peta Grains have a particularly low PAR resistance, so when they occur in pairs Mesh of Light and Darkness or Demon Binding Ring can pin them in place for virtually the entire battle, giving you an opportunity to recover SP if you so choose.

By far the longest and most technical battle up to this point, Rinnosuke has no less than eight different forms you have to fight against. For his initial form, you need to reduce his HP to below one million before he starts switching through his elemental forms. Rinnosuke can take on any of his six elemental forms, each with its own HP and a weakness to its opposite element (i.e. fire form is weak to cold). Each element keeps track of its own HP; each must be reduced below one million HP, at which point he'll use Form Destruction and that form will be destroyed. All six need to be destroyed before his final form.

All in all, you need to deal at least 2,080,000 damage to him at minimum to cycle through all his forms and defeat him. If you are unable to deal enough damage fast enough to force Rinnosuke to use Form Destruction, he will instead use Form Shift; this 'stores' his form for later. It is not considered destroyed, and in fact it slowly 'regenerates' health offscreen until he throws it out again (this regeneration is quite small, at 6000 HP per turn, but this can pile up). In general, you need to destroy a form within six or seven of his turns before he uses Form Shift.

Rinnosuke has an enormous variety of attacks to throw at you, which change depending on his current element, although most of his elemental attacks are generic party attacks. In his initial and final forms, he has the dangerous Rasetsu Fist, which deals around 6000 damage, ignores Defense, and can paralyze. All forms have access to Scarlet Gold Sword and Start of Heavenly Demise, strong composite attacks that also drain 1 TP from their victims.

This fight is largely a battle for survival; if you're at an appropriate level and making full use of defensive buffs, most of Rinnosuke's attacks aren't truly dangerous, just strong. Note, however, that he's completely immune to debuffs and can't be poisoned or paralyzed, so concentrating on your own buffs is the only option. He becomes much more dangerous when his final form is reached; he'll use World-Shaking Military Rule, greatly increasing his offensive and defensive stats. He only has 200,000 HP in this form; burn him down quickly before he overruns you.
