Ice Release, combination of Water and Wind natures was first shown by Haku Yuki, and an ability of the Yuki Clan. There have been variations shown such as snow release, which could be derivative of the ice release, much how water can be used to form syrup or mist.
Ice has a weakness to Lightning, as it can cut through while Earth can effectively shatter it physically. weak to sound as well, which can shatter the crystals by vibrating it hard enough.
Neutral to fire, as fire melts ice but then the water overpowers the fire. I guess you could almost consider this a weakness in a sense because the ice would still lose its physical form.
Strong to Wind and Water, both of which would just make the ice colder and grow more strength.
