Minor Pact

You can trade a piece of your soul or life energy to gain greater powers from a powerful Patron. Choose one warlock invocation that you meet the prerequisites for. You gain the following benefits:

• Your Charisma score increases by 1, to a maximum of 20.
• After each long rest you can take a -4 penalty on your Strength, Constitution, Intelligence or Wisdom score. When you do, you can use the chosen invocation until the end of your next long rest. You lose this penalty after your next long rest.

If you already have an invocation from a class, you instead take a -2 penalty.
