Raising your hand in a claw-like gesture, you create icy claws that erupt from the ground around a creature of your choice within range. The target must make a Dexterity saving throw. On a failed save, the target takes 12d8 cold damage and the icy claws close around it, forming a solid block of ice in which the target is encased. The block completely covers the space around the target and is transparent, but nothing can physically pass through it. While encased in the block, the target is restrained and it must make a Strength saving throw at the end of its turn. On a failed save, it takes 3d8 cold damage and is still encased and restrained, on a success the target takes half damage and is no longer encased or restrained.
