Some half-elves in Faerûn have a racial trait in place of the Skill Versatility trait. If your DM allows it, your half-elf character can forgo Skill Versatility and instead take a trait based on your elf parentage.
High Elf Descent
A half-elf of moon elf or sun elf descent can forego Skill Versatility and instead choose the high elf’s Elf Weapon Training or Cantrip.
