I disagree. That's part of the fun of the game, discovering little tricks and in-game bonanzas. And it's nice to find a bug that actually helps. There are certainly enough to frustrate the crap out of you. And I wonder if that orb bug was intentional, A little too easy to discover.
Discovering little tricks like that, yes, that's neat to do. But once you know it works, you might as well just cheat yourself up. Unless you want to sit there for an hour gaining the 1000 XP over and over.
True. I went back to an earlier save point and am going thru the end again trying things out a little differently, and you're right, I probably won't bother with that orb. It's an old toy now. My new toy is enchanting mephit guano with armor class bonus. Fun!
