Demon's Gimp

You’ve have signed into a submissive contract with a demonic entity. The demon has collared you, which provides the following protection:

• Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.
• Demonic Protection: You learn the Demonic Bondage spell. You can cast this spell without expending a spell slot. Once you cast this spell in this way, you can’t do so again until you finish a long rest. You can also cast this spell using spell slots you have. The spell’s spellcasting ability is Intelligence, Wisdom, or Charisma when you cast it with this feat (choose when you gain the feat).

• Demonic Gimp Suit: When you are hit by an attack roll, you can use your reaction to project a tight, spandex-like demonic gimp suit over your body. You gain temporary hit points equal to your current hit points. You can use this reaction a number of times equal to your proficiency bonus divided by 2, and you regain all expended uses when you finish a long rest. You can only have a single gimp suite activated at a time. When your gimp suite is still active outside of combat, add 2 to charisma checks.
