I am playing in a campaign as a level 4 Artillerist artificer from the May 2019 UA. I am thinking of taking Magic Initiate (wizard) as my feat, and learning the find familiar spell with it. I am curious about one thing in particular.
The plan right now is to have the familiar take the form of a weasel/rat that will ride on my turret's back. Would the familiar be able to take the Help action to, for instance, grant my ballista turret advantage on its attacks?
