+2 Dexterity and +1 of your choice to any other stat that isn't Dexterity.

You have advantage on death saving throws.

In your pre-dead life you acquired skills and abilities just like everyone else. You gain one skill proficiency and one tool proficiency of your choice.

You can see in darkness up to 60 feet, both magical and non-magical. You cannot discern color. 

If a bone or limb is detached from your body you can replace it with a relevant bone as an action. You may detach limbs and other bones as a bonus action. Detaching body parts does not cause you to take damage but causes you to lose maximum HP. Reattaching a bone or limb restores maximum HP.

As an action you may collapse into a non-moving skeleton. You are undistinguishable from another skeleton and whilst in this state you are prone and your movement is 0.

While living, a wealth of knowledge you carried but in death your memory serves to be unreliable. You may cast any one spell of any class using a spell slot once per short rest.

Postmortem existence grants the dead ancestral knowledge of a powerful dodging technique allowing them to flip backwards to avoid on coming attacks. This action moves you to an adjacent 5ft space.
