I just had a great idea for a quest..
You put a rock on top of the Keldrin fountain.. and make it in the code so that when you "look" at it by pressing P (or your pack button) you get LCK, SP, EXP, RP, or coins! But also, theres a risk, because you can LOSE all that stuff, too! And also, your storage can get cleared!
I think it came to me in a dream.
