High Elf One Shot

Hi all! Player here. As stated, we're going to be doing a one shot this week, and I was looking to see if I could please get some ideas? I have never played a High Elf, and I know the typical classing seems to be Wizard or Rogue. Any thought or ideas on how to play a wacky class or just some guidance on how to build a decent High Elf would be much appreciated.

For this Oneshot, the only restrictions are:

Race: High Elf

Level: 15

Multiclassing is allowed, so are all source books and some homebrew options(depending).

Again, anything helps!😊
