> **Casting Time:** Action > **Range:** 90 feet > **Components:** V, S, M (a tentacle) > **Duration:** [[Concentration]], up to 1 minute Squirming, ebony tentacles fill a 20-foot square on ground that you can see within range. For the duration, these tentacles turn the ground in that area into [[Difficult Terrain]]. Each creature in that area makes a STR saving throw. On a failed save, it takes 3d6 Bludgeoning damage, and it has the [[Restrained]] condition until the spell ends. A creature also makes that save if it enters the area or ends it turn there. A creature makes that save only once per turn. A Restrained creature can take an action to make a STR (Athletics) check against your spell save DC, ending the condition on itself on a success. **Classes:** #Wizard
