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.
Wood Elf Descent
A half-elf of wood elf descent can forgo Skill Versatility and instead choose the wood elf’s Elf Weapon Training, Fleet of Foot, or Mask of the Wild.
