You’ve manifested some of the power of a wraith, granting you the following benefits:

• Increase your Dexterity, Constitution, or Charisma by 1, to a maximum of 20.
• You gain resistance to necrotic or poison damage.
• As an action, you can make a melee attack roll against a creature within your reach, you make the attack roll with disadvantage while you or the target is in sunlight. You use your Dexterity modifier for its attack and damage rolls. On a hit, the target takes 2d8 necrotic damage, and must succeed on a Constitution saving throw (DC 8 + your proficiency bonus + your Constitution modifier) or its hit point maximum is reduced by an amount equal to the damage taken. This reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hit point maximum to 0. The damage increases by 1d8 when you reach 11th level (3d8), and 17th level (4d8). You can roll all of the attack’s damage dice twice and add them together, but your Strength score is decreased by 1d8, you die if this reduction reduces your Strength to 0. Otherwise the reduction lasts until you finish a long rest.
