Ensnaring Strike

As you hit the target, grasping vines appear on it, and it makes a STR saving throw. A Large or larger creature has advantage on this save. On a failed save, the target has the Restrained condition until the spell ends. On a successful save, the vines shrivel away, and the spell ends.

While Restrained, the target takes 1D6 Piercing damage at the start of each of its turns. The target or a creature within reach of it can take an action to make an Athletics check against your spell save DC. On a success, the spell ends.

Using a Higher-Level Spell Slot: The damage increases by 1D6 for each spell slot level above 1.
