Path of Frost

Path of Frost is a death knight ability that allows the death knight and their party or raid members within 50 yards to walk 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.)
