> [Spells (SRD p)](srd_spells.md) --- # Black Tentacles - Alias: [Tentacules noirs](hd_spells_tentacules_noirs.md) - Source: (SRD p121) -  4th-level conjuration - **Casting Time :** 1 action - **Range :** 90 feet - **Components :** V, S, M (a piece of tentacle from a giant octopus or a giant 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.
