due to being dead you have become smarter but can no longer interact with the world as well as you used to

You are immune to poisons poisoned and diseases as you do not have a physical form you still take damage from physical attacks as they drain on your mind and willpower 

Thanks to your ethereal form, certain advantages and limitations have been granted to you. You may now move through any creature or object as if it were difficult terrain, taking 1d10 force damage if you end your turn inside a creature or object. In exchange, you can only carry ten specific items on your person, of which you must spend 8hrs trying to incorporate said items into your ethereal form with any kind of armor equipped taking up four of these limited item slots. It'll take another 8hrs to remove an item from your form, the item returning to its original physical form once done so and freeing up an item slot.
