Wight's Power

You have developed traits similar to those possessed by a wight, granting you the following benefits:

• Increase your Strength, Constitution, or Charisma by 1, to a maximum of 20.
• As a bonus action, choose one creature you can see within 30 feet of you. The next time you hit that creature on this turn with a weapon attack, all damage dealt by the attack becomes necrotic damage, and the creature takes an extra 1d6 necrotic damage from the attack. The target 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.
• When you finish a long rest, you can choose to give yourself disadvantage on attack rolls and Wisdom (Perception) checks that rely on sight, while in sunlight. In exchange you gain resistance to either necrotic or poison damage (your choice), for 24 hours.
