Water Net

Overlapping tendrils of ice sprout from the ground in a 20-foot square starting from a point within range. For the duration, this ice turns the ground in the area into difficult terrain.

A creature in the area when you cast the spell must succeed on a Strength saving throw or be restrained by the net of ice until the spell ends. A creature restrained by the ice can use its action to make a Strength check against your spell save DC. On a success, it frees itself.

When the spell ends, the conjured ice melts away.
