Fastest way to reach level 99?

[Eddie]

What's the best grinding area for late game? Thank you!

[MageKing17]

You can't reach level 99; it maxes out at 98.

[Eddie]

Thanks for not answering my question.

Consider using Cheat Engine to modify the experience value. The experience value is a double-precision floating-point value. Try searching for values within the current experience value range of -1 and +1 to find the experience value and modify it

I don’t have a definitive answer, but I would:
1. Look through the encyclopedia to find the highest-XP, lowest-HP enemy.
2. Find a room where such enemy appears.
3. Equip your best XP-boosting accessories (and best weapons).
4. Grind and grind by killing that enemy, leaving the room, entering the room, and repeating until level 98.

Alternatively, finding a room with several enemies that you can quickly kill (e.g. with Lux’ Orb power) may be another option.

For my money, the corridor before the fight with Victor has the best XP density. The enemies net 840 XP base, I believe, each traversal, and with a particularly helpful drop (which one of the enemies in the room drops), it takes maybe 30 seconds per traversal. There might be better, but I can't think of one offhand.

[Eddie]

In the end I settled for the corridor with drones and androids, but it takes FOREVER to level up once you get past 65, so I gave up. Waiting for a DLC, maybe I'll fill my encyclopedia then. Thanks all.

Is there an achievement or in game aspect requiring the grinding up to L99? Or just a personal goal?

[Your Majesty]

Nope. No actual achievement for max level or filling either the Daemon Encyclopedia or Item Encyclopedia. Which is a godsend, because the drop rates can be downright awful and you probably only need Level 55 or so to actually beat the true final boss anyway.

[Eddie]

No, thanks God :) It's just I felt bad looking at all the ? in the encyclopedia :)

[Defmonkey]

Well thats good news, so really no need then unless you want to one shot the bosses.... but sounds like one will be spending a lot of time for diminishing returns.

55?! Yeesh, I got there at 44, no wonder I'm losing 2/3 of my HP per hit.

For anyone who wants the grind, I found that using the lumina burst skill to kill the shinigami and the parade marshal in the last hallway before the final fight with Baal is the most efficient.
1. Enter the hallway from the left side (not the side with the save point/vending machine)
2. Use lumina burst and make sure both enemies die
3. Exit the hallway immediately on the left, use a whip on the mushrooms to replenish MP
4. repeat

The whole cycle takes about 3 seconds and is netting over 260xp at lvl 65 each time with Vertex type IV and PRO type III equipped.

My favorite post-game grinding spot is 2-3 rooms to the left of the top-right save point in the recycling center. You alternate between the room with two Jack Frosts and a room that starts with two Yuki-onnas and one Yukinko (plus others not accessible from the very entryway). Run back and forth between the rooms, using a whip on the Jack Frosts and shooting the others (alternating with Lux's moves as appropriate). 351 base EXP per cycle.

There is another advantage here (though this could be a bug, and hence might be patched out in a later version). It appears that enemy drops do not check the maximum items cap.
Yuki-onnas drop Ice Cream, and Yukinkos drop Turbo Regenerators. Hence, if your goal is to grind for the post-game superboss, you can get a little peace of mind with a few extra healing items. (Granted, surviving long enough after a bad hit to use the healing item is tricky, but it is still nice to have.)
