You get one spell from any school when you select EK as your subclass at level 3. Given the verticality and map design of BG3, either jump or feather fall are both prime choices. At level 4 you get a feat, and among the options is Magic Initiate. This will get you 2 extra cantrips and another 1st level spell. On table top this first level spell would be restricted to one use a day, but as it currently is implemented in BG3 you can use spell slots. Who knows if that will remain in the final release build.
