Your Constitution score increases by two, and your Strength score increases by 1

Thanks to your powers from beyond the grave. You have superior vision in dark and dim light. You can see 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 not be turned. As well you become immune to being Charmed, Frightened.

You are resistant to Poison damage and the Poisoned condition.

Your body no longer desires food or water. You do not have to eat or sleep as your bodily functions have ceased, though you still need to take a long rest to recover from exhaustion. During a long rest, you can engage in light activity like reading a book or being on watch and still get the benefit of a long rest.

Unfortunately, you cannot be healed by a spell, potion, or magical effects, other than your Relentless Nature trait unless it specifically states that Undead creatures can be healed from its effects. You cannot be revived from death short of a Wish spell.

• Starting at level 3, if you are below half your hit point maximum, but not at 0 hit points, at the start of your turn, you regain 1 hit point plus Constitution Modifier. You can do this twice per long rest
• When you are reduced to 0 hit points but not killed outright, you can drop to 1 hit point instead. You can’t use this feature again until you finish a long rest.
• You know the general distance between you and any creature involved in you goal, such as a person you seek vengeance against, or someone you pledged to defend. At times this awareness will be stronger than others, it can be affected by proximity, magical effects, your emotional state. This awareness fails if the creature is on another plane of existence.
