You are not held down by flesh restrictions unlike most other creatures, and due to your awakened state you are more intelligent than those would suspect. However, due to your unsettling visage it is harder for you to get along with others. Your dexterity gets a +2 and intelligence gets a +2, but your charisma takes a -1 penalty.

You do not age and given time the necrotic energies that sustain you, your wounds will heal at approximately the same rate as a mortals.

You have the speed of the race you were in life.

You can read and write in the languages your race in life knows. You also can understand the spoken language, but can only be understood when speaking common.

You are immune to poison damage and exhaustion, and you can't be poisoned. You don't require air, food, drink, or sleep.

When you are reduced to 0 hit points, but not killed outright, you can drop 1 hit point instead. If you do, you fall to a pile of bones, become prone, and are considered to be under a similar effect to the feign death, but can be detected by spells. While subject to this condition, you are unable to move or take actions other than using an action to end this effect. You can't use this feature again until you finish a long rest.

You  can detach your bones. If you do so you lose control over that portion of your body until it is put back in place. Instead of attaching your original bone to yourself you can attatch another corpse's bone in its place. If you do so you gain one of the following benefits if the original race has one of these traits and the flesh is intact.

• You gain a swim speed of 20 feet for 2 limbs, 30 for 4 limbs. (pre-requisite: corpse's race must have a swim speed of 30 feet. If lower or higher then your gained swim speed is reduced or increased by the difference.)
• You gain their natural attack if any
• or You gain 1 hit point per hit dice of original creature if you take all 4 limbs

You determine the benefit at first time of attaching, after which it is considered a magical item with that benefit that can only be used by the undead. 2 limbs that are not skeletal take up 1 attunement slot while attached, and cannot be attached if you have no free attunement slots.
