This achievement seems impossible, I have seen so many others getting it but with serveral attempts I have not found the way to complete this.
Most of the time, I get spiked because it NEVER shows the white marks, So i'm moving back and fourth from 2 big plates, and I think its paused for a second or two and then BAM! Slapped in the face by spikes I didn't even see from the ground. I'm not standing anywhere close to walls, and i'm getting sick of running this dungeon just for one cheev that never works.
Any idea on how to get it? ._.
