Tendrils

Grasping black ooze like tendrils sprout from the ground in a 20-foot square foot radius. For the duration, these tendrils turn the ground in the area into difficult terrain.

Up to 6 creatures in the area when you cast the spell must succeed on a Strength saving throw or be restrained by the entangling tendrils until the spell ends. A creature restrained by the tendrils 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 tendrils slither back into the ground.
