**Prerequisite:** Spellcasting or Pact Magic feature Studying occult lore, you learn one [[Eldritch Invocations|Eldritch Invocation]] option of your choice from the [[Warlock]] class. Your spellcasting ability for the invocation is Intelligence, Wisdom, or Charisma (choose when you select this feat). If the invocation has a prerequisite of any kind, you can choose that invocation only if you’re a warlock who meets the prerequisite. Whenever you gain a level, you can replace the invocation with another one from the warlock class.
