Thorvald’s Ultimatum

You create a 100ft. cube field of powerful binding energy. For the duration, the area becomes difficult terrain.

Creatures of your choice that enter the spell's area for the first time or start their turn there must succeed on a Wisdom saving throw or be paralyzed for the duration. Creatures can repeat the saving throw at the end of each of their turns, ending the condition on a success.

On your turn, you may use your action to surge the binded creatures with rippling energy. All paralyzed creatures this way in the cube suffer 6d10 force damage.
