Walkthrough

16F: Mystery Battlefield

The stairs to 17F (and long-awaited showdown with Yukari) are just to the right of the relay point, but to get there you have to flip four switches. Three are in the upper left, lower left, and upper right corners of the map, while the last one is in the lower middle. There's some useful treasure hidden behind the sigils, but you'll have to beat the Great Stamp on 15F to access them. It's recommended you do this before fighting Yukari anyways, as you'll need all the help and levels you can get.


Notable Enemies

Two enemies are particularly dangerous on this floor. Gold Sorceresses possess extreme levels of magic power and extremely high defenses as well, and in many cases it is far smarter to run from fights involving them, as you risk a high chance of a party-wide death from moves like God Press and Ether Flare.

Helbelmares are also dangerous - they've got the second-lowest HP of any enemy on this floor, but they also have the highest defenses. You'll need to use an attack with defense-piercing qualities, like Silent Selene, or otherwise obscene attack power, like Knockout in Three Steps, in order to take them down. They also have 0 DTH resistance, so even Narrow Confines of Avici has a chance to instant-kill them. If they get a turn, they'll either heal everyone for a ridiculous amount of HP, or, if they're the only ones left, they'll cast Huge Earthquake to deal incredible amounts of physical damage to your party. Until you can take them down reliably, run.

However, by this point in the game, most enemy encounters can be fairly dangerous. Obsidian Knights and Impurity Spreaders can stand up to a beating and dish one out, so crack open your bigger attacks. The remaining enemies on this floor tend to be faster overall and like to throw out PAR and PSN effects, so try to do your exploring on this floor with at least somewhat PAR-resistant characters, in order to avoid having your whole party stunned and set up for a beating by something more fierce.

Yukari

HP Level Recommendation EXP Skill Points Drop
650,000 75-90 80,000 64,000 ?
Yukari has three different phases - one from 650k to 400k HP, one from 400k to 200k, and the last one underneath 200k. Each time she enters a new phase she uses Djinn Storm, which reduces the entire party's SP to zero, including reserve characters. During the first phase, she tends to use extremely powerful row attacks like Flying Insect's Nest, so prepare your party accordingly. In the second phase, she uses Barrier Release to boost her own defenses, and starts using party-targetting attacks like Objective Border more often. In her third form, she'll use her strongest offensive spells and IN Quadruple Barrier, which increases all her stats significantly and makes surviving almost impossible. Defensively, she has high stats in both DEF and MND and is completely immune to paralysis, but debuffs will work, so reducing her speed is a must. She's also weak to NTR. Her first two forms aren't particularly difficult to survive defeat if you're the right level - debuffing with Narrow Confines of Avici and hitting her hard with your glass cannon characters in the back row should work well. The third form is what's really threatening - if you can't kill her before or right after she uses IN Quadruple Barrier, it's as good as losing, but your party's offense will be crippled due to Djinn Storm. The most reliable way to kill her is to buff your attackers as much as possible before Djinn Storm hits, swap them into the back row to recover SP, then debuff Yukari's defenses and take down her remaining 200k HP all at once. Suwako and Marisa will do excellent damage with Croaking Frog/Master Spark, and Kaguya can either use Swallow's Cowrie Shell for respectable damage or give Suwako another shot of Croaking Frog.
