So this may seem like a weird question, but here goes.
Can someone with a familiar take the School Familiar archetype without having the school class feature?
Can someone without a patron take a patron familiar?
I am looking at Arcanist with both of these. The Unlettered Arcanist, swap sorcerer/wizard list for witch and gain familiar spell storage. However, I was not taking the school savant or school exploit but do still plan to focus on a particular school (Shadow Illusions).
