There are a lot of different ways Feats (and magical items) refer to the requirement of having a Familiar:
- Levels in a class that grants a Familiar
- Familiar class feature
- Spellcaster with Familiar class feature
- Familiar
- Ability to acquire a Familiar
- ...you get the idea.
Are any of these meant
not to work on Familiars acquired in a specific way (Arcane Bond class ability, Witch's Familiar class ability, Arcane Bond bloodline power, Familiar class ability, Summon Familiar class ability, Tumor Familiar discovery, Tattoo Familiar class ability, et cetera), or is it all just sloppy terminology?
