Ghast's Prowess

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

• Increase your Strength or Dexterity by 1, to a maximum of 20.
• You gain resistance to necrotic damage.
• You gain darkvision out to a range of 60 feet.
• You have claws that you can use to make unarmed strikes. When you hit with them, the strike deals 1d6 + your Strength modifier slashing damage, instead of the bludgeoning damage normal for an unarmed strike.
• Once per turn, when you hit a creature with an attack made with your claws, you can force the target to succeed on a Constitution saving throw (DC 8 + your proficiency bonus + your Constitution modifier) or be paralyzed for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
