Don't quit playing after defeating Corbenik and seeing the credits roll. Why? Among other reasons......there's an epilogue. And this guide is to help you through it to the final ending.
After beating the game you and Elk recieve an e-mail from Aura warning of bad happening and are asked to help stop it. Naturally you have to take Elk with you so who's the other party member to bring with? I took Black Rose with me the first time through and Helba the second. Helba made getting through the baddies much easier for me. By the way. This is no ordinary dungeon. It's 15 floors deep and chock full of Data Bugs. The boss is relatively easy. Getting there is the hard part.
Preparations:
* Make absolutely certain Kites infection level is completely in the green before entering. Once inside it will skyrocket up into the red which means you're always living with the chance of auto-game over.
* Bring tons of healing items and the "blood" stat boosting items.
* If possible, get at lE Kite up to Level 99 beforehand. Being at the highest level will slow the growth of your infection meter ever so slightly.
* On a relataed note allow Kite to finish off each and every monster. As you should know by now, letting him finish badguys slightly lowers his infection level.
* Have Kite equipped with Sora's Blades if you got those earlier on. High critical hit rate is great, plus it makes Protect Breaking enemies happen faster.
* During battles set your party to "Operation Recover." That way you can focus on defeating the monsters. Also, when up against enemies with "Physical Tolerance" be sure to manually control with spells your teammates cast.
This next bit of advice is opinion-only. Some people say when up against multiple Data Bugs you should attack and defeat only one at a time. Data Drain is the weakest form of Drain power so yes, using other forms causes your infection level to rise faster....but as said earlier, you're going to be in the Red range most of the time anyway.
So against multiple Data Bugs you're often given the opportunity to whack a couple or more at once with Twin Slash or some variant of it. So I say go for it. Protect Break as many as you can at once then hit them with Drain Arc. My reasoning is the less you have to use *any* Drain attack the less chance there is of getting Game Over'd.
The Correct Path
Anyway~on to the best path for making it through this dungeon with the loW possible chance of enemy encounters. This is one dungeon you don't want to attempt to clear all rooms of.
1.) N, N, W, N, N, E, N
2.) N, W, N, E, N, N, E
3.) E, E, N, N, W, N, E, E
4.) E, E, N, N, N
5.) N, N, N, N
6.) N, N, E, N, N
7.) N, N, W, N, N, E
8.) E, N, N, W, W, S, S
9.) S, E, N, E, S, E, N
10.) N, N, N, W, N
11.) N, N, N, N, N, E, E, S, S, S, S
12.) S, S, S, W, W, N, N, N
13.) N, W, N, N
14.) N, E, S
15.) S, E, N, N
N = north
E = east
W = west
S = south
I think that's about all you'll need to know.
