I’m thinking for my Jedi wizard, her ability to cast magic will be based on a number of different mediums. For spell 1 she uses a magic stick, for spell 2 she writes a rune down, for spell 3 she does some somatic Naruto hand sign bullshit, etc. the reason for that is because she’s self taught/homeschooled. She just learned whatever worked for her. 

Bit of a mixed bag when it comes to what she used as a focus, but her fancy wizard stick is generally what she’s accustomed to the most since she’s trained with it for years.
