Lamia's Prowess

You have developed traits similar to that of a lamia, granting you the following benefits:

• Increase your Strength, Constitution, or Charisma by 1, to a maximum of 20.
• You gain proficiency in Deception. If you already had proficiency in Deception you gain expertise in it instead.
• As an action, you can make a melee spell attack against a creature within your reach, using your Charisma modifier for the attack roll. On a hit, the target is magically cursed for 1 minute. Until the curse ends, the target has disadvantage on Wisdom saving throws and all ability checks. 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.
