I had a great idea! edit: That will never make it into the game!
What if, after we beat, say, the fifth crypt, if we find a secret passage and avoid invisible spike traps, we find some hall where we get to battle CraigStern, give or take a few other forum members? If we won, maybe we could win a special orb that combined the effects of non-resistance orbs or even teach us a dual-element attack.
Granted, programming CraigStern, KZ, and Ertxiem as bosses would probably take a while, but I even planned out the stats!

Yes, I know it would take long and delay the final release of TSoG... but it would be funny.
