Is it allowed to edit the save file to remove orb flags (spell unlocks)? If this is allowed, you can get some useful spells from orbs every time (Deercoy and Earthquake are useful on all bosses)

The Game Rules say "No save file manipulation to gain an advantage", but I'm not sure what it means.

What exactly does this prohibit? ・Operation or deletion of ghost wand? ・Manipulation of spell unlock status? ・Manipulation of boss defeat status? (full heal drop or not)
