Spectral tentacles of crushing seawater rise from the ground in a 20-foot square you can see within range.

• When a creature enters the area for the first time on a turn or starts its turn there, it must succeed on a Strength saving throw or be restrained until the spell ends.

• Restrained creatures take 4d8 bludgeoning damage at the start of each of their turns.

• A restrained creature can use its action to make a Strength check against your spell save DC, ending the effect on a success.
