Path of Frost is a death knight ability learned at level 66. It allows the death knight and their party or raid to walk or ride on water for 10 minutes. This effect maintains while the player is mounted and can be cast while mounted.
It should be noted that enabling this ability and then dropping onto water will no longer result in death or damage. In the past when this was used, the water would act just as if you were dropping onto normal ground. (Note: This is not always the case.)

- There are a number of uses for this ability besides the obvious, such as fishing in open water and eating on the surface of the water after fighting beneath.
