How to unlock the Darkslide achievement in Shovel Knight: Specter of Torment - Definitive Guide
You can do this anywhere there are rails to grind on. Some notable suggestions being: The room in the Tower above where Specter Knight sits on the rooftop, the Stranded Ship and near the end of the second last stage.
The three tricks are: , + and +. You need to perform all three without touching the ground. It is safe to run and jump off a wall, as long as you land back on a rail. Although I was able to unlock this trophy/Feat with a combination of rail grinding and using the Rail Mail to grind on the floor, I was unable to unlock it solely using the Rail Mail to floor grind. In the end, grinding on actual rails is much easier.
