I haven't played pen and paper in years. I miss it.
I remember one DM we had let my friends an I cheat once in a while. We had character abilities a bit out of whack, and once in a long while we'd find items that were just silly at our level. I think our DM had the itch for us to level faster than was realistic and so slipped in crazy items out of his own lack of patience.
What is the most outrageous item you've ever put in a game? Maybe you created it. Maybe you let your players craft it. Maybe it was an item out of the books you plopped down in there for folks to fight for.
Let me know.
I'm feeling nostalgic today.
