The only entrance to the tower was a 200' long corridor, 20x20 in dimensions. The floor is a permanent prismatic wall. The rest of the corridor is filled with an antimagik shell (permanent) which extends to just 1" above the floor. The walls are perfectly smooth and greased, as is the ceiling. Half way down the corridor is a break in the antimagik shell 1' in width, in it it an INVISIBLE adamantite gate with an exceptional lock (DC35)
I saw that, laughed, and skipepd the rest of the module.
Not so bad. The other proposed solutions work, but here's what I'd expect:
Okay, you have your Rogue with maxed-out balance and a set of immovable rods, right? Of course you do. He just makes himself a walkway as he goes, checking for traps as he goes, runs into that gate, takes 20 on that, and continues onward to be eaten by the Half-Dragon Tarrasque the module's writer stuck in after that to vent his frustration over a failing marriage.
After the Rogue has gone through, the Wizard just casts reverse gravity, and gently comes to rest at his point of bouyancy (so his center of gravity is right at the lower edge of the antimagic field)... Unless the wizard is exceptionally fat, he should be okay. (Of course, the wizard does some other little tests first to make sure that this will work.) The door's been taken care of, so it just takes a hearty push to send the wizard sliding on across to the other side and into the left-most mouth of the Super-Empowered Deluxe Enlarged Axiomatic Demogorgon which has since eaten the tarrasque (and, vicariously, the Rogue)
The Cleric just happens to have a simple flying carpet, embroidered with his favorite holy symbol, which will also do just fine with a foot of space to operate in. He is then eaten by Mecha-Hitler.
The Fighter, on the other hand, has no worries: The Mecha-Hitler is too big to fit through the hallway, and if he stands on a box or something the antimagic field will give him full coverage from its spells. He just pulls out the longbow he got at first level and fires away (he has infinite arrows somehow and probably infinite rations, too) waiting for natural 20s. Mecha-Hitler is slain and the fighter gains 2000 Billion XP and 32 sp, which he will spend on ALE AND WHORES!
I love this game.
