Aspiro Frigis

The caster creates a gust of frigid wind that encases whatever it touches in ice, freezing it in place. Any creature caught in the radius must make a dexterity saving throw. An encased creature that failed the saving throw becomes restrained, they have their movement speed reduced to zero and are unable to make actions. They can roll a strength check at the end of every turn in an attempt to break free of the ice. The initial spell also causes 2d6 of cold damage.
