# Black Tentacles *(Evard's Black Tentacles)* > [!info] Spell Details > | | | > |---|---| > | **Level** | 4th | > | **School** | [[Conjuration]] | > | **Casting Time** | 1 Action | > | **Range** | 90 feet | > | **Components** | V, S, M *(a piece of tentacle from a giant octopus or squid)* | > | **Duration** | Concentration, up to 1 minute | > | **Classes** | Wizard | --- ## Description 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 the area into **difficult terrain**. When a creature enters the affected area for the first time on a turn or starts its turn there, the creature must succeed on a Dexterity saving throw or take **3d6 bludgeoning damage** and be **restrained** by the tentacles until the spell ends. A creature that starts its turn in the area and is already restrained by the tentacles takes 3d6 bludgeoning damage. A creature restrained by the tentacles can use its action to make a Strength or Dexterity check (its choice) against your spell save DC. On a success, it frees itself. --- ## At Higher Levels This spell does not have an upcast effect.
