Re: Dragon Monster Girl Quest?
I was stuck on that same part until I just coincidentally happened to figure it out.
First off, the creator uploaded maps on their blog. I can't post URLs yet, so you'll have to find it yourself. They're really helpful, though, since all the fake walls are noted, as well as many of the objects (treasure chests, bosses, etc.) I only found the maps after I got stuck, though!
To get further, hopefully you have the Old Jar from the ice area. It's at one of the fake bottoms, in a chest. Anyway, use it with either of the little jellyfish (?) girls in your party, and choose not to drink afterward. Then check it out in your inventory and drink it, and the Old Jar becomes the Jar of Thirst. With that, you can suck up the patch of water in your way on floor 47 just by examining the water.
The only times you have to have specific teammates seem to be:
1) Pit in first area (Dracky)
2) Shadow room in ice area (Shadow knight) -> Jail Key (unlocks those gray doors)
3) Scorpion Land (off the left side of the fire islands area, walk through the lava) (All three scorpions are required to enter)
Hope I'm not forgetting any.
I beat the game just earlier, but I still have a completionist's urge to go back, since I never found the fourth secret dungeon until I consulted the maps (it's on the overworld- I looked all over in the ice area for that kind of wall formation for nothing

), and I don't get what to do there. There are just gray slimes I can't seem to catch and an unopening door. Hmm. If anyone can help me out there, let me know.
