Witch's apprentice

While not a full-fledged Warlock yourself, you've learned a thing or two from one. You might've been taken in as a disciple by one or just rummaged through their grimmoire a few times.

• You learn two cantrips and one 1st level spell from the warlock spell list. Charisma is your spellcasting ability for your warlock spells.
• You gain one arcane focus from any class that can be used to cast the spells you learn from this Feat.
• You gain two Eldritch Invocations from the Warlock's Class Features. You cannot choose an Eldritch Invocation that has a level requirement, even if you meet that requirement.
