Noted, thanks. Went to the merchant and the list says I need three pieces of ruby for a Potential up, but I have four and he doesn't accept them - does the merchant actually require five pieces of ruby? Either way I'll be on the lookout for materials and such - not sure if they're just in the desert, though, but I'll keep looking.

Hi SwordyNate!
The problem you described regarding ruby pieces was due to incorrect variable entry in the game data. I have updated the game to version 1.1.2, and with it, fixed several minor bugs, including, precisely, the problem you described.
I apologize for the wait in responding! I wish you a good adventure in Jento Chronicles: Reawakening! :)
