Re: Stuck at Chapter 4 [Taking Flight]
No problem. Always happy to help someone enjoy this fine game.
Okay, so neither of those quests are requirements for Chapter 5.
For future reference, Electric Bones are in Dijenel Borderland and Phema Mountains. (Not saying you should have access to them, just saying that once you do, that's where you'll find 'em)
What are you missing for the Gnome Stone? (All 3 ingredients should be available in the Yuidora Mine)
Aside from that, all I can think of is maybe get stronger? (level up your ppl) Or try to get 100% complete in every area you have access to. (you can do one while working on the other, too).
If that doesn't work, I don't know what else to suggest...
EDIT: I don't know what level your characters actually are, but apparently, you'd need Wil at level 14, Yuela lvl 15, Emilita lvl 17 and (if you have her) Suina lvl 11.
If that doesn't help, I'l like you to tell me what the last events you saw were (as much as you can, and preferably in order if possible.)
EDIT2: Just so you know, I was able to make the Gnome Stone in Chapter 1 (did it just now). The Materials are all available in the Yuidora Mines - Training Grounds.
