Platform Hero

At the moment, the easiest way to do this achievement is just to leap onto ANY platform, and stay just barely on the ledge of it where the pulsating lightning won't hurt you and just hang out for a few minutes. Once you've done that just jump to a new platform and BAM you should get your achievement. This method worked on three of my characters as of Thursday, March 7, 2013.

I can't help but feel these comments are WAY over-complicating things.

All I did to get this was wait for the gap to reach the starting area where I was, jump onto the platform when the gap was there, then just follow it. It's like a snake, it won't ever pick a square way away from you. It's literally a snake, where there will be either 2 or 3 open platforms. Just wait for the next one to open, jump to it, repeat. Free achievement.

If you just jump on to the platform when its clear and scoot as far as possible to the left bottom corner, you can just sit there and the chieve will pop for you, no need to jump to another platform. But you must be in the lowest left corner (from the direction of walking into the vault, directly up to the platforms.)
