Moving Terrain?

[Scribble]

Have any of you successfully used moving terrain in your games?

Things like:

Bridges that are collapsing or shriking, so the jump DC gets harder as you go...

Carts that people can jump into, maybe giving them a faster move...

Elevators people can jump onto to get to different places... (maybe to gain some sort of advantage...)

Maybe some sort of moving platforms that will "link up" at certain initiative counts making the jump DC harder or easier depending on when you go in the round?

In the War of the Burning Sky campain, there is an encounter where the PCs are trapped between some nasty critters and a slowly moving wall of fire. At the low levels, the wall was a credible threat. By moving the wall 5' on every characters turn, it moved up at a rate of 30' per combat round and pressed the players to act swiftly.

The encounter was quite memorable...

A couple times over the several years I've played/GM'd... One of the best uses of moving terrain was actually in last years D&D tourney module, you had to keep from getting killed by monsters on moving platforms while navigating said platforms to reach the shut off buttons.

Yep! One of my favorites was an inward pointing force field. The players crossed the outer rim, and accidentally triggered it. Then they saw the giant statue of a strange bird with violet eyes. Violet eyes projecting two beams of force - one that blocked their way forward, and the other that blocked their way back. Then the Rune Golem (courtesy of Mike Mearls) attacked!

Every round the outer wall moved in five feet out of the initial 25 feet. Let me tell you, they were shouting at each other as it got closer and closer.
