Tentacle Grasp

A writhing mass of translucent tentacles erupts from a point on the ground you can see within range, filling a 10-foot square. Each creature in that area when the tentacles appear must succeed on a Strength saving throw or become restrained. A creature that starts its turn in the area must also make this saving throw.

A restrained creature can use its action to make a Strength (Athletics) check against your spell save DC. On a success, it frees itself.

Any creature restrained by the tentacles takes 2d6 psychic damage at the start of each of its turns as alien whispers pour into its mind from your patron.
