Sheesh, what were you playing, Dark Sun?
Nope, but
let me paint you a picture.
It was an original setting, and the plot of the campaign was essentially that we needed to gather the eight
MacGuffins. We had already gathered six of them when the GM essentially told us where to find the last two.
We did as he said, and were transported through time and space (somehow. I wasn't paying much attention to the plot) and ended up in a hallway facing two guys. It was an encounter suitable for a party about 3 or 4 levels higher than us, and it left us all pretty drained.
We enter the door at the end of the hall, and we're in a giant room with one of the
MacGuffins on a pedestal in the center. We move towards it, and suddenly a
Bone Ooze
drops from the ceiling. Here I'd like to note that that thing's an encounter suitable for guys level 21 (which is
epic level) while we averaged about level 15.
Soon, the ooze starts gobbling us up, and with my party dying left and right, I look the thing up in the book and throw a spell at it that ends up transporting it to an alternate dimension.
Then a hostile
phoenix
appears, which is
three levels tougher than the ooze. Since it's listed as a good-aligned creature, I attempt to reason with it. For my trouble, I get burninated.
The last two guys left alive try to run to the
MacGuffin before the phoenix kills them. One of them doesn't make it, and the second manages to grab it. Then our DM says to him "Roll Fortitude".
We later found out just what number he had to get, and it was impossible for any of us to make without a natural 20. And that's the story of how that campaign ended.
