Tentical grasp

Grasping tenticals  come out of the casters body. For the duration, these tenticals turn the 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 entangling tenticals until the spell ends. A creature restrained by the tenticals 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 tenticals will disapear.
