Iceglide (Su)

At 10th level, a winter witch can move effortlessly at her base land speed through ice or snow. This leaves behind no tunnel or hole, and doesn’t create any ripple or other sign of passage. While icegliding, a winter witch can breathe normally. A control water spell cast on an area containing an icegliding winter witch flings her back 30 feet in a random direction, stunning her for 1 round unless she succeeds at a DC 15 Fortitude save. A winter witch can use this ability for 10 minutes per day. This time need not be consecutive, but must be spent in 1-minute increments. Activating this ability is a swift action.
