A frost drake can, as a standard action, spit a ball of liquid that bursts into a cloud of freezing mist. This attack has a range of 60 feet and deals 7d6 points of cold damage (DC 18 Reflex half) to all creatures in a 20-foot-radius spread. The mist cakes all surfaces in the area with a sheet of slippery ice that turns the area into difficult terrain for 2d4 rounds, after which the ice cracks or melts enough to revert to the normal terrain features in the area. Once a frost drake has used its freezing mist breath, it cannot do so again for 1d6 rounds. The Reflex save is Constitution-based.
This ability works like spider climb, but the surfaces the drake climbs must be icy. It can move across icy surfaces without penalty and does not need to make Acrobatics checks to run or charge on ice.
