***Prerequisite:** Spellcasting or [[Pact Magic]] feature* Studying occult lore, you learn one [[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 [[Eldritch Invocation|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.
