Your choice of race affects many different aspects of your character. It establishes fundamental qualities that exist throughout your character’s adventuring career. When making this decision, keep in mind the kind of character you want to play. For example, a halfling could be a good choice for a sneaky rogue, a dwarf makes a tough warrior, and an elf can be a master of arcane magic.
Your character race not only affects your ability scores and traits but also provides the cues for building your character’s story. It’s worthwhile to consider why your character is different, as a helpful way to think about your character’s background and personality.
