You can breathe air and water.

You have resistance to non-magic bludgeoning damage. You also have advantage on ability checks you make to escape a grapple.

You have 4 tentacle limbs sprouting from your head. They give you the following benefits:

• You can use your tentacles to manipulate objects and hold tiny objects. They cannot be used to wield weapons.
• You have advantage on ability checks you make to initiate and maintain a grapple. You can choose to use all 4 of your extra limbs to grapple one target, freeing up both of your arms.
• You can use your tentacles to make an unarmed strike in place of your arms.
• These tentacle limbs have a range of 10 feet.

As a reaction out of combat, you can change the color and texture of your skin to blend in with your surroundings, giving you advantage on Dexterity (Stealth) while remaining stationary. In combat, you must use your bonus action.

You can use your action to spray a pitch black stream of ink, which spews in a 15 feet line stemming from you. All creatures in the area must make a Dexterity saving throw. (8 + your Dexterity modifier + your proficiency bonus)

If the creature fails it's saving throw, it is blinded for a number of turns equal to your proficiency bonus. A blinded creature may attempt to make another Dexterity saving throw at the end of each of it's turns. On a success, the blindness condition ends. After using your ink spray, you cannot use it again until you complete a short or long rest.

Your character knows at least three languages: Aquan plus two languages you roll or choose from the Standard Languages table. Knowledge of a language means your character can communicate in it, read it, and write it. Your class and other features might also give you languages.

The Standard Languages table lists languages that are widespread on D&D worlds. Every player character knows Common, which originated in the planar metropolis of Sigil, the hub of the multiverse. The other standard languages originated with the first members of the most prominent species in the worlds of D&D and have since spread widely.
