Good lord, I come back from Thanksgiving dinner and suddenly I have a bajiliion things to reply to. Can't you just be satified in knowing that you destroyed the universe?

Canti3000 and Ae: To the North is the ice slope, to the East is the wall of debris, to the South is the icesmithy, and to the West is Scholar Sam's Academy. I think. Don't bother with the guy on the wave, because the only way to break the ice would be to chisel it, and you'd just end up shattering him into a bunch of tiny pieces if you tried that. People don't like being brought back to life once they've been shattered into a bunch of tiny pieces.

BoggyB: The boulder is being pushed down the slope by a currently unknown agent. Notice how they wait until you're just high enough for a fall to the ground to be fatal. Also, like Faw himself said, he can only teleport to cities you have been to, and only certain ones at that. You never gave him the chance to explain, but that's why he couldnt warp back tp Upper Placespot on his own. Also, the Enchantresphere can't talk, but you're somewhat close to a reasonable plan. Not that close, though.

Fawriel: The slope is too slippery to run up or down. You'd fall and start sliding, and then the snowball would nail you.

I would have just let you try all your theories and fail miserably, but I think it's safe to say we're all tried of this accursed Snowball of Death. Remember the limitations of this world; your previous attempts all failed because you acted without thinking. Remember the factors at work here: magic ice, non-magic snow, 70 degree/357 foot slope, 100 foot rope, magic chisels, and a boulder. Also remember that your party has to make it up the slope alive. Now gimme something good, you Uberbob fanatics.
