Chains of Cania

A mass of barbed, freezing chains burst forth from the ground in a 20 ft radius emanating from a spot you can see within 60 ft. All creatures of any size except tiny sized creatures must succeed a Strength Saving Throw against your spell DC.

On a failed save, the creature(s) take 4d4 piercing damage plus 2d10 cold damage and are restrained until the spell ends. A creature can use its action to attempt to make the saving throw again to end the effect on themselves.

On a successful saving throw, the creature(s) take half the piercing and cold damage and are not restrained.

At higher levels: If you cast this spell using a spell slot of 6th of higher, increase the cold damage by an additional 2d10 for each spell slot above 5th.
