The first worlds I think it’s good for a start is: Konosuba(for its magic and skills), Harry Potter(I know this is cliché, but it’s one of the best starter worlds, you can get with. Charms for versatility, magical items for utility, Occlumancy for mental protection and mental control, and if you can get the Animagus or Metamorphmagus traits. Also Arithmancy could help with spell creation. And I guess transfiguration would be cool to. sorry for the long winded Mouth vomit.), Fairy Tail (could be great to get: Archive magic, Requip magic, Dragon/God/Demon slayer magic, Soul takeover, maker magic, Arc of Embodiment, Ruin magic, Magic items.)… I can’t think of any other good starting locations. So I hope this helps you get some ideas.
