Binding Ice

A cone of icy energy bursts forth in a 30ft. cone. Each creature caught within this cone must make a Constitution saving throw. On a failed save, the creature takes 3d8 cold damage and is hindered by clinging ice for 1 minute or until another creature uses its action to break the ice away. A creature that is caught up in the ice has its speed reduced to 0. On a successful save, a creature takes half damage and is not hindered by clinging ice. 

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, increase the cold damage by 1d8 for each slot level above 2nd.
