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

Your claws are natural weapons, of which you have proficiency with. If you hit with them, you deal cold damage equal to 1d6 + your Strength or Dexterity modifier (your choice).

Your body is semi-physical, much more corporeal than other ghosts but not quite solid. This semi-corporeal form doesn't reduce damage taken to your 'body', unlike other ghosts,  but the appearance is almost identical to those other ghosts. You can spend 15 feet of movement to pass through 5 feet of solid material, or simply 10 if it's through a thin body of material, as long as the material is not made of lead. If you end your turn in a space of solid matter, you are shunted out to your last location outside of the structure, taking 2d4 force damage. In addition, because of your undead nature, you have resistance to Necrotic and Cold damage.

You have telepathy, although you can only communicate feelings and images through your telepathic bonds. To establish a bond, you must choose a creature within 30 feet of you that you can see and spend a bonus action. For the next 24 hours you can freely communicate with this creature your feelings, and any images you think of, as long as both of you remain on the same plane of existence.

Your creature type is undead, and you don't need to eat, drink, or sleep. 

Your creature type is Undead and your size is tiny.
