While you have a humanlike shape, you can wear clothing and armor made for a Humanoid of your size. As a bonus action, you can extrude a pseudopod that is up to 6 inches wide and 10 feet long or reabsorb it into your body. As part of the same bonus action, you can use this pseudopod to manipulate an object, open or close a door or container, or pick up or set down a Tiny object. The pseudopod contains no sensory organs and can’t attack, activate magic items, or lift more than 10 pounds.

The magic that runs in your veins heightens your natural defenses. When you take damage, you can use your reaction to roll a d6.

If the Mending spell is cast on you, you can spend a Hit Die, roll it, and regain a number of hit points equal to the roll plus your Constitution modifier (minimum of 1 hit point).

You can add a d4 to one attack roll, ability check, or saving throw you make, and you can do so after seeing the d20 roll but before the effects of the roll are resolved.
