Area	4 yard radius x Rank
Duration	Rank x 1 Rounds
Casting	Verbal, Somatic
Action	Standard
Cost	2 Mana
Effect	Twists the elemental water in the atmosphere and drops the temperature to summon an instant sleet squall. The sleet will limit visibility to 5 yards, snuff natural fire, and counter magical fire of a lower rank. Flying creatures will suffer impaired fly speed, with a penalty equal to rank, and flying creatures sized small or less will struggle to remain airborne. All horizontal surfaces under the storm will become coated in ice, rendering the surfaces extremely slippery. If there is any present wind ( natural or magical ) then vertical surfaces facing upwind will also become coated with ice. Movement on the ice covered surfaces costs double movement points to avoid risk of falling down. Faster movement and any significant melee combat will require an Dexterity based Acrobatics check to avoid falling down. The sleet is permanent until melted and then drained or evaporated, and will accumulate as it would naturally.
