Bone Garden

You curl your finger and skeletal arrns begin to crawl their way from beneath the ground 20 foot radius centered on a point within range. For the duration, the area is considered difficult terrain. When a creature starts its turn or moves into, it must succeed on a Strength saving throw or be grappled. At the start of a grappled creature's turn, it can make a Strength (Athletics) check contested by your spell save DC to break the grapple. Any creature that can each a grappled target can use its action to attempt to break that target's grapple by succeeding on a Strength (Athletics) check against your spell save DC.
