Here's a working adjustment to add an arcane familiar, although it isn't finished and hasn't been tested much.

Herolab's built-in arcane familiar stuff is implemented as level dependent abilities, and which expect to be bootstrapped from a configurable or class helper to work properly.

Remember that you need to check the boxes for "arms reach" and/or "within a mile" in the in-play tab in order for any benefits from a familiar to show up on the hero.
