Eldritch Adept (Pact of the Chain)

You gain the following benefits.

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 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.

Pact of the Chain

You learn the Find Familiar spell and can cast it as a Magic action without expending a spell slot.

When you cast the spell, you choose one of the normal forms for your familiar or one of the following special forms: Imp, Pseudodragon, Quasit, Skeleton, Slaad Tadpole, Sphinx of Wonder, Sprite, or Venomous Snake.

Additionally, when you take the Attack action, you can forgo one of your own attacks to allow your familiar to make one attack of its own with its Reaction.
