Your Dexterity score increases by 2, and your Constitution score increases by 1.

You are Medium.

Your base walking speed is 30 feet.

You can see in dim light within 60 feet of you as if it were bright light and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.

You have a climbing speed and swimming speed equal to your walking speed. In addition, at 3rd level, you can move up, down, and across vertical surfaces and upside down along ceilings, while leaving your hands free.

Your tentacles are special appendages. As an action, you can use one of them to try to grapple a creature. Each one is also a natural weapon, which you can use to make an unarmed strike. If you hit with it, the target takes bludgeoning damage equal to 1d6 + your Strength modifier, instead of the bludgeoning damage normal for an unarmed strike. Immediately after hitting, you can try to grapple the target as a bonus action. These appendages can’t precisely manipulate anything and can’t wield weapons, magic items, or other specialized equipment.
