I would think that if you wanted to do both, you would need to split the power & control up enough to complete both effects and most likely this would be incredibly hard to do, but I can come up with a couple right off the top of my head.
In keeping with the ice methods already mentioned.
Name or Chant: Ghiaccio Coprire
Element: Water
Power: 8, 2 weapon, 3 for the Maneuver, 2 to effect the entire zone.
Control: 8, Needed for the attack roll.
Effect:
This spell creates ice over an entire area, making it grow up around everyones feet in the area, causing damage as it freezes the flesh it contacts. Targets exposed to the spell, need to make an athletics check at a difficulty of 3 or have the aspect of Bound in Place put on them.
