I only played it on a rom a long time ago...

Whatever the gil is, random or not....
Let me rethink what I'm going to say.
I think that you can wander into nasty territory easily and get killed immediately by monsters like Wizards and Soldiers. (I'm sort of guessing on the names). Ogres too. But, the Ogres are fairly killable, even for a group of weaker characters. Ogres seem to give lots of Gil and they drop mithril, which is awesome if you're risking your wak warrior neck to kill ogres for it.

And you shouldn't bother raising soul for a killer who will just lose it eventually. Generally. Like somebody said, there are methods of doing this, but it's always got the Red Mage syndrome.

Edit: You may be past the point where you'd be in awe of ogres by now.
