^ Any Tips.

um its not impossible. its just hard. level up like a mofo and equip the most powerful items. duh.

it might not be such a bad idea to get the Magus ring and equip heal

What are you having trouble on?

Meh, I beat it pretty easily after a few tries. The hardest floor is the one with the room that has a whole bunch of cave trolls. When you get to them, just take them out one at a time. Also, the last two rooms are some of the easiest.

Explosion is the absolute best attack spell Char has. it uses next to no MP and it jumps between enemies screwing them easily. those Cave Trolls which are "hard", are no match when you use Explosion on them. if you spam that spell, Nest of Evil is a bit easier. its just not a good spell on bosses. except the Fake Trio, its alright with them.

also, when you get to the last, 7th, floor, the one that has a save room with it, unequip EVERYTHING from your current character, and in Char's case, give her only the Encyclopedia as an item. then enter the room and re equip everything. this will make the last NoE fight braindead.

Honestly, I don't know why so many people insist on unequiping all their gear to fight Doppelganger(Total waste of time when I'm using it master subweapons). to It only takes to uses of 1000 blades to kill it, and you should be able to avoid geting hit too much to need recovery items as it isn't a very aggressive opponent.
Just make sure Charlotte doesn't have any of her powerful spells equipped.

Actually, spamming 1000 blades makes all the Nest of Evil bosses easy wins, save for Aguni and the Fake Trio.

It is challenging for sure. But don't try to complete it all at once. Just go a little at a time until you think you are ready for the harder floors.

i llusion fist DUH!!!!!!!!!!!!!!111 ur talking to an illusion fist fan here =D

OK HERE IS SOME MASTER ADVICE AGAINST CAVE TROOL DOPPLEGANGER & THE TREVOR FAKES .CAVE TROOL= use one thousand blades dopleganger turn into any caricter with the weakest weapon like --- enciclopedia and weakest stats enter the room the doplegager will morph into you and fight with these stats switch into the opisite caricter
