Ice Slick

Standard Action | V, S | 5 ft radius
Instantaneous | Reflex partial
Create a blast of intense cold, coating all solid surfaces in the area with a thin coating of ice (rough terrain). Creatures in the area take 1d6 cold damage + 1 point per caster level (max +10) and fall prone (reflex halves, no fall). Moving requires a DC 10 Acrobatics check. Failure by 4
or less means the creature can't move (reflex save or fall). failure by 5 or more means it falls.
