you now breathe underwater and gain a climbing speed and burrowing equal to your movement speed and take the pressure up to your level times 100 metres below the surface.

Below the Surface

Starting at 2nd level, you now gain an advantage in stealth and you gain tremorsense of 60f when in difficult terrain.

Monsters of the Deep

 

you can now use your wild shape to turn into monstrosities that are up to a quarter of your level.

Death's strut

Starting at 6th level, moving through nonmagical difficult terrain costs you no extra movement. You also can use your wisdom save instead of any other save against traps.

When you reach 10th level, you can’t be frightened by monstrosities or fiends, and you are immune to poison and disease.

Immunity to the Deep

When you reach 14th level, you become immune to all effects that the terrain does to you, also all allies within 30ft of you become immune to difficult terrain.
