Elemental Dash

You immediately move a distance equal to your walking speed. This movement does not trigger any attacks of opportunity and you may move through any creature as if it were normal terrain. If you do, the creature must make a constitution saving throw or take 2d6 cold damage and have its movement reduced by 10ft for 1 minute. On a successful save the creature takes half damage and its movement is not reduced. If you end your movement inside of a creature both you and the creature take 2d6 force damage and you are pushed out of its space in a random direction.
