(Level-three Crúac Ritual)
Marena, Goddess of winter, sickness, and death is beckoned to aid the Koldun against his enemies. So invoked, she causes chill winds to kick up within Koldun's presence. These winds hinder the movement of others and can even cause frostbite.
For as much as 100 yards, chill winds whip out in one direction from Koldun's position. Each success of the Ritual is subracted from the speed of any who move towards the Koldun. In addition those within these unatural winds suffer one point of bashing damage per round from the wind chill and cold temperatures. There may be secondary effects that the storyteller may decide to include, such as frozen puddles of water, extreme frost on nearlby objects and such.
