Aspect of Envy

Your covetous malice has made you a living avatar of the sin of Envy. You gain the following benefits:

• Increase your Intelligence or Charisma score by 1, to a maximum of 20.
• You have advantage on Wisdom (Insight) and Charisma (Deception) checks.
• When a creature hits you with an attack, you can use a reaction to learn what ability scores the creature has that are better than your own ability scores. You can choose one of these scores and reduce the creature's score by 1d4, while increasing your own same score by the number rolled. This feature lasts for one minute. If you use this ability again before the minute is over, the new score change automatically replaces the previous change. 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.
