Spell Description
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 🔨 Bludgeoning damage and be by the tentacles until the spell ends. A creature that starts its turn in the area and is already by the tentacles takes 🔨 Bludgeoning damage.
A creature 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.
