Eiame's Ice Mist

A rolling, cold mist emanates from you two feet above the ground. Each creature in a 700-square-foot area (see below) originating from you must make a Constitution saving throw. On a failed save, a creature takes 3d8 cold damage and falls prone. On a successful save, the creature takes half as much damage and remains standing.

The affected area becomes heavily iced and is treated as difficult terrain for 1 minute unless dispelled. The ice can also be melted by magical fire.

The area of effect can be configured in any way along a line of sight. Common configurations are: 5' X 140', 10' X 70', 15' X 45', 20' X 35', or 25' X 30'.

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.
