Revenant

You have come back from the dead with a thirst for vengeance. After being slain unjustly and overwhelmingly, your hatred of your murderer (or murderers) has grown so great that it has made itself tangible, infusing your body with your angry spirit. Clawing your way out of the grave, you gain the following benefits:

• The DM chooses a creature or creatures for you to be bound for vengeance. You always know the distance and direction to your quarry, even if you and your enemy are on different planes of existence.
• If you die when your quarry lives, you return to life in 24 hours, either inhabiting your old body or forming a new one if your previous body was destroyed. If you form a new body, you don't keep any equipment that was on your previous body.
• You can't be Charmed or Frightened while you are tracking your quarry.
• Your type is undead, not humanoid and you are susceptible to all effects that apply to undead except an effect caused by your sworn enemy such as Turn Undead or Turn the Unholy.
• Your melee attacks deal an extra 2d6 damage to any creature against which you have sworn vengeance.
• You regain 1 hit point at the start of each of your turns while you are below half your hit point maximum.

When your quarry dies, you die and can't be restored to life by any means.
