Stained Half-Elf (5e Race Variant)
From D&D Wiki
The strained half-elf is similar to the standard half elf, but they can only increase one skill by one, instead of two, and they gains the following traits:
Inborn Magecraft. Stained Half-Elves may cast magic missile, once, as a 1st level spell. At 3rd level, magic missile may be cast as a 2nd level spell, and as a 3rd level spell by 5th level. Charisma is the spellcasting ability for this spell. You regain the ability to cast magic missile in this way after a long rest.
Keen mind. You always know which way is north. You always know the number of hours left before the next sunrise or sunset. You can accurately recall anything you have seen or heard within the past month.
