Gift of the Yugoloth

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

• Increase your Strength, Dexterity, Constitution, Intelligence, or Charisma by 1, to a maximum of 20.
• You gain resistance to acid and poison damage.
• When you are forced to make a saving throw against a spell or other magical effect, you can use your reaction to give yourself advantage on the saving throw. 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.
