CryoPulse

You continually create and focus cold energy into an orb between your hands. As you do so, a cold wave pulses out each round damaging and potentially slowing then freezing any creatures other than yourself each turn. The range grows to 10 feet on second and subsequent turns. Bodies of water/liquid within range becomes frozen (6" deep if pool is deeper). Creatures trapped beneath can STR (12) save to break through.
