Your Constitution score increases by 2, and one ability score of your choice that isn't Constitution increases by 1.

You are a walking skeleton without flesh. Your creature type is undead instead of humanoid. As such, spells like cure wounds don't affect you, and you are immune to spells like crown of madness or dominate person because they specifically target humanoids. Necrotic damage inflicted upon you from leveled spells heal you instead of dealing damage.

You are immune to poison damage, being poisoned, and diseases. You do not need to eat or breathe, and any food you do attempt to eat falls through in your jaw and into your rib cage. Rather than sleeping, you enter an inactive state for 6 hours each day. You do not dream in this state; you are fully aware of your surroundings and notice approaching enemies and other events as normal.

Your sight has been restored by necromancy, giving you unnaturally sharp vision. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of grey.

You can restore any limb after it being detached or destroyed by simply finding a suitable replacement, then using your action to attach it.

You may, as an action, collapse your form into a pile of bones. While you remain motionless, you are indistinguishable from a normal pile of bones. In this state, you are prone and your speed is 0.

You can speak, read, and write Common, and Necril. Necril is the language of the undead.
