Chains of Oblivion

You extend your arms towards a creature within range, and tendrils of freezing water reach for, and attempt to halt your targets movement. The target must succeed on a Strength Saving Throw or take 2d6 cold damage and have its movement reduced to 5 feet. It it is flying, it descends at a rate of 60 feet per round. On a success, they take half as much damage only.

The target can repeat the saving throw at the start of each of its turns.

At higher levels; You can target one additional creature per spell slot level.
