So they were in your inventory? Maybe you're playing an older version not affected by the bug. You should be fine then. The blue orb is on the fourth floor if I can recall correctly.
I hate to keep bothering you, but I got the blue orb and opened the hidden room, was I supposed to eat the rotten fruit or not? I ate it and it said I had a strange power welling up and then it took me back to town with a skull in the corner, did I die or something else happen? thank you again for putting up with me.
Yeah, that's what it's supposed to happen. You pass out from it, but awake with a newly found power (which is the ability to learn up to 12 spells). There's no death in the game (aside from game over screens, which are rare). The power you unlock carries over in the sequel as well, so it's a good thing to have whether you are currently doing a magic-oriented playthrough or not.
