The Arcanist - Harry Potter Wizard Variant

Hi, I'm looking for testers and feedback on this Wizard Variant. It's my first Homebrew and want to check balance levels

Its a Harry Potter inspired variant designed for my wife's first D&D; character. A rework of the core Wizard mechanics and three subclasses from the Harry Potter world, namely the Animagus (reworked single wildshape), Magizoologist (reworked revised Beast Conclave) and Potion Master.

I realise there were some RAW examples that could have fit but wanted to have something easily recognisably 'Harry Potter'
